• Do not install on wooden walls or near flammable surfaces.
• Install on a wall or strong structure suitable to bear the weight.
• Do not install in rooms where the people live or where the prolonged
presence of people or animals is expected.
• Installation of these models can be carried out vertically or horizontally
with a maximum inclination as indicated in the FIG. 05 and 06.
• Hardware and software maintenance on device entails opening the front
door. Check that the correct installation safety distances are observed in
order to allow routine check and maintenance operations.
• Provide sufficient working space in front of the inverter that allows to
make connections on the wiring box.
• If possible, install at eye-level so that the status LEDS can be seen easily.
• Install at a height which takes into consideration the weight of the
appliance and in a position which is suitable for servicing, unless suitable
means are provided to carry out the operation.
• Final installation of the device must not compromise access to any
disconnection devices that may be located externally.
• Respect the minimum distances from objects around the inverter that could
prevent the inverter installation and restrict or block the air flow (FIG. 03).
• In case of multiple installation position the inverters side by side keeping
the minimum distances (measured from the outer edge of the inverter) for
each inverter (FIG. 01 and 03). If the space available does not allow this
arrangement, position the inverters in a staggered arrangement as shown
in the FIG. 02 so that heat dissipation is not affected by other inverters
below.
• The vertical installation in also permitted on a structure which must be
composed of a support for the attachment of the bracket and one for the

4. Lifting and transporting
4.1 Transport and Handling
Transport of the equipment especially by road, must be carried out
with means for protecting the components ( in particular, the electronic
components) from violent shock, humidity, vibration etc. During handling,
do not make any sudden or fast movements that can create dangerous
swinging.
4.2 Lifting
FIMER usually stores and protects individual components by suitable
means to make their transport and subsequent handling easier, but as a
rule, it is necessary to utilize the experience of specialized staff in change
of loading and unloading the components.
In order to lift the inverter easly are present two handle (14) and two lifting
rings (09).
ATTENTION –ADo not lift several units or parts of the equipment at
the same time unless otherwise indicated.The ropes and equiment
used for lifting must be suitable for bearing the weight of the
equipment.
4.3 Unpacking and Checking
The packaging components must be removed and disposed of according
to all applicable laws and regulations of the country where the equipment
is being installed. When you open the package, check that the equipment
is not damaged and make sure all components are present. If you notice
any defects or damage, stop unpacking and contact the carrier, and also
promptly inform the FIMER Service department.

6. Installation planning
6.1 Sizing the ground cable(s)
ATTENTION –ASize the cable(s) in accordance with NEC and any
local codes.
ATTENTION –AThe wire must be large enough to handle the
maximum ground fault current (92 A) that the PV system might
experience.
ATTENTION –AThe warranty is void if the inverter isn’t connected to
ground through the appropriate terminals.
Follow site wiring diagrams and grounding plans. At a minimum expect this
to include:
• A PV array equipment ground conductor (EGC), to be landed on the EGC
connection point (16) located on the left external side of the inverter.
• A protective earth (PE) conductor, to be landed on the protective earth
connection point (37). The terminal accept a ring cable lug, suitable for a
M6 size threaded insert (Torque to 11Nm / 8 ft-lb).
6.2 AC overcurrent protection
To reduce the risk of fire, connect only to a circuit provided with an
overcurrent protection in accordance with the NEC (ANSI/NFPA 70). The
inverter must be connected only to a dedicated branch circuit provided with
the maximum branch overcurrent protection device (OCPD):
PVS-60-TL-US
Type
Typical installations use a 3-pole/600V
rated bi-directional thermalmagnetic
circuit breaker, UL489 or equivalent.
Maximum Current/Voltage 100 A / 600 V
• Verify that the PV module is listed for use in 1000Vdc systems in
accordance with local electrical codes.
• It is installer's responsibility to provide external disconnect switches and
OCPD as required by NEC and other prevailing regulations.
• The inverter is designed without an isolation transformer and must be
installed per NFPA 70, 690.35 with an ungrounded PV array.
6.3 String Fuse sizing (-S and -SC models only)
The correct sizing of the positive side (+) and negative side (-) string fuses
to be used to protect from “return currents” is very important because it
reduces the risk of fire and damage to the PV array. Fuses must be sized
for each single string in the PV array.
The fuse rating (Irated) must be based on the string current and on the
sizing guidelines provided by the fuse manufacturer to avoid untimely
tripping. As a general guideline, the photovoltaic modules’ short circuit
current (Isc) and the following formula give an estimate of the fuse rating:
Irated > (1.4 ≈ 1.5)*Isc
Fuses must be chosen from among the standard commercially available
ratings, selecting the size that is closest to the calculated value.
The maximum string fuse size is 20A.
6.4 Choice of grid output connection type (AC side)
The medium voltage trasformer, i.e. the grid (distribution system), must
face the inverter as a grounded WYE, whose Neutral may or may not be
brought to the inverter. Set the switch (S1) based on the configuration of
the output connections:
• 3WIRES position (lines 1, 2, 3 + GND).
In this case, the inverter creates its own “virtual” neutral).
The DIP switch S1 on the AC Filter board must be set for “3 WIRES”
before the inverter is commissioned.
• 4WIRES position (lines 1, 2, 3, Neutral + GND).
The DIP switch S1 on the AC Filter board must be set for “4 WIRES” before
the inverter is commissioned.

7. Mounting instructions
The mounting bracket (01) can be used to install the inverter on a vertical
or horizontal support
• Position the bracket (01) perfectly level on the support and use it as a
drilling template. (FIG. 07)
ATTENTION –AIt is the installer’s responsibility to choose an
appropriate number and distribution of attachment points. The choice
must be based on the type of support (wall, frame or other support),
the type of anchors to be used and their ability to support 4 times the
inverter’s weight (4 x 71 kg (156.5lb)=284 kg (626lb) for all models).
Attach the bracket to the wall with at least 10 attachment screws.
• Depending on the type of anchor chosen, drill the required 10 holes (A) to
mount the bracket. Put at least four screws in the upper side and at least
four in the lower side.
• Fix the bracket to the support.
• Lift the inverter using the handles (14), or another appropriate lifting
device. The inverter is pre-equipped with lower support (24) which allow
it to be temporarily put vertically on the floor to make it easier the lifting.
• Insert the heads of six anchor point (03), present on the bracket into the
slots on the rear of the inverter. (FIG. 08 and 09)
• Install the 4 fixing braket (02) on the 4 corner of the inverter (using 8
screws). (FIG. 10)
• Remove the protective cover from the connector of the wireless antenna
located on the left side of the inverter. Install the wireless antenna by
screwing it into the specific connector (10). (FIG. 11)
• Open the wiring box front door (04) turning the 3 key-lock (08) in “OPEN”
position and proceed with the wiring and connections depending on the
model.
• Install a cable conduit on the AC opening (18):
1. remove the plug and preserve the adapter ring (40)
2. install the adapter ring (40) on the conduit (FIG. 12)
3. install the conduit on the AC opening (18)
• Remove the plugs on the DC openings (17) and install the conduits on it
(PVS-60-TL-US-S model).

WARNING –BTo avoid risks of electrical shock, all wiring operations
must be carried out with the disconnect switch downstream of the
inverter (grid side) opened and applying LOTO procedure on it. Be
careful not to change round one of the phases with neutral!
ATTENTION –ACaution! Connect the ground before starting the grid
connections.
ATTENTION –AKeep the resistance of the wires to a minimum
between the OCPD and the AC terminals, to ensure the correct work
of the protective devices.
ATTENTION –ASize conductors per NEC Article 310 -- use
90°C wire only; conductors must be sized according to operating
temperature range and continuous current ratings.
ATTENTION –AAC output wire must be UL listed wire rated minimum
600V.
8.1 Installing the ground cable(s):
• Attach the DC side ground cable(s) to the equipment grounding conductor
connection point (16).
• Attach the AC side ground cable to the protective earth (PE) connection
point (37).
Both above connection point accept a ring cable lug, suitable for a M6 size
threaded insert (Torque to 11Nm / 8ft-lb)

8.2 Grid output connection (AC side)
The medium voltage trasformer, i.e. the grid (distribution system), must
face the inverter as a grounded WYE, whose Neutral may or may not be
brought to the inverter:
Lines 1,2,3, Neutral + GND (“four-wire”) OR Lines 1, 2 3 + GND (“three-
wire,” and in this case, the inverter creates its own “virtual” neutral).
• Confirm the size of grid conductors 4AWG to 4/0AWG (copper or
aluminum).
• Confirm the right setting of the switch on the AC filter
board (in the ACWB) for the neutral connection to the grid:
- 3WIRES → WYE connections with no neutral (R+S+T+GND)
- 4WIRES → WYE configurations with neutral (R+S+T+N+GND).
• Run the AC cable through the conduit openings (18).
• Connect the grid conductors (R, S, T, Neutral) to the respective terminals
on the AC output terminal block (38) (FIG. 15 and 16).
• Torque to 14Nm /10.3ft-lb.
• Give each wire a pull test to confirm the connection is secure.

ATTENTION –ADo not place objects of any kind on the inverter
during operation!
ATTENTION –ADo not touch the heatsink while the inverter is
operating!Some parts may be very hot and cause burns.
WARNING –BTo avoid risks of electrical shock, all wiring operations
must be carried out with the DC disconnect switch internal and
external (applying LOTO procedures on it) to OFF position and with
the external AC disconnect switch to OFF position (applying LOTO
procedures on it).
WARNING –BThe DC disconnect switch disconnects the DC current
from the PV panels in the “OFF” position. The inverter will stop
producing power, but DOES NOT disconnect the AC from the grid.
WARNING –BIn case of presence of internal DC disconnect switch
only, there will be live parts internal to the inverter with a consequent
risk of electrical shock.
WARNING –BConfirm the PV array’s input polarity is correct.
WARNING –BConfirm the PV array has no ground leakage current.
WARNING –BThe transformerless design of the inverter requires
that the PV array to be floating with respect to ground per NEC
690.35.
WARNING –BPer NEC 690.35, wires from the PV array must be
UL-listed, 1000V minimum rating, 90°C minimum temperature rating.
DC-side connections may vary depending on the inverter model:
9.1 PVS-60-TL-US-S and PVS-60-TL-US-SC Models
9.1.1 Preliminary operation
These inverter versions have three input channels which work
independently of one another, which can be paralleled by leveraging a
single MPPT.
The independent configuration of the input channels (MPPT) is set at the
factory. This means that the parallel bar (supplied) is not be installed on
the parallel MPPT connection points (41), and that the software setting
“Independent channel mode” is
performed on the inverter.
If is necessary to put the 3 input
channels in parallel, the parallel bar
(supplied) must be installed on the
parallel MPPT connection points
(41) (FIG. 17), and that the software
setting “parallel channel mode”
should be performed on the inverter;
this setting can be done by different
way:
• During the commissioning wizard
phase (STEP 4).
• In the dedicated section of the
internal webserver “Setup section >
Setup DC side > Input mode”
To install the parallel bar follow the procedure below:
• Place the parallel bar (supplied) on the connection points (FIG. 18).
• Install the 3 screws with washers supplied (torque 4Nm / 3.0 ft-lb).
These inverter versions have 15 string inputs (5 for each channel). Each
input string is protected by fuses (+ and -).
WARNING –BFuses are sized for single-string currents only. Strings
may be not paralleled in the PV array.
9.1.2 PVS-60-TL-US-S Model

closed! Make sure irradiation is stable and adequate for the inverter
commissioning procedure to be completed.
Commissioning could be carried out in two different ways:
• Via “Installer for Solar Inverters” mobile APP - Recommended
mobile APP for commissioning single inverter as well as multi
inverter solar plant.
• Via Web UI (access point wireless network) - Integrated Web User
Interface enabling setting parameters and performing commissioning of a
single inverter (multi inverter support is not provided). Recommended as
alternative method for performing single inverter commissioning.
11.1 Commisioning via “Installer for solar
inverters” mobile app
“Installer for Solar Inverters” is the advanced FIMER mobile APP allows to
simplify commissioning, parameter settings and troubleshooting of FIMER
string multi-inverters in large scale solar plants.
Even in case of single inverter installation it can be consider the most
suitable professional tool to be used. “Installer for Solar Inverters” mobile
APP is available for mobile devices with an Android version of 6.0.1
or greather (iOS mobile devices support will come soon) and could be
downloaded and installed from Play Store.
Commissioning procedure:
• It’s highly recommended to connect the inverters in ethernet daisy chain
(with or without ring) before executing the commissioning procedure.
Make sure that all the inverter being commissioned features the last
firmware version (updating can be executed via Installer for Solar
Inverters mobile APP).
• Supply the input voltage from the photovoltaic generator to the inverter.
ATTENTION –AMake sure irradiation is stable and adequate for the
inverter commissioning procedure to be completed.
The main steps to complete the commissioning procedures are listed below:
• Installer for Solar Inverters mobile APP installed on mobile device.
• Enabled Aurora Vision installer account allowed to use the mobile APP.
The account can be created in the mobile APP directly following the
dedicated wizard procedure.
• Manual claiming of the inverters to be commissioned.
The claiming process consists of indicating which inverters are to
be commissioned.
Claiming process can be executed by scanning the QR codes of all
the inverters being worked and putting the selected inverters into the
working list. Please insert in the list inverters belonging to the same
inverters family; no more than 40 inverters by time can be configured
together. As an alternative of QR code scanning, claiming process
can be executed by selecting manually the SSIDs associated to the
Wi-Fi networks generated by each inverter to commission and inserting
Product key when requested. Both QR code and Product key are provided
on the Communication identification label stuck onto each inverter. The
Communication Identification label is divided in two separate parts by a
dashed line; take the bottom part and apply it on the plant documentation.
(it’s recommend to create a plant map and apply the Communication
Identification label of each inverters in the right position of that map).
NOTE –DAbove steps are valid for executing any available
funtionalities of the Installer for Solar Inverters mobile APP.
• In order to launch the installation wizard and so complete the
commissioning procedure please click “Commissioning” button.
If needed click prevently on “Firmware update” button for aligning
the firmware of all the inverters in the list to the last version
(internet connection is needed).

any other functionalities of the Installer for Solar Inverters mobile
APP please contact FIMER customer support. For any other specific
settings of parameters of single inverters please refer to “Description
of the Web User Interface” chapter.
11.2 Commisioning via web UI (Access point
wireless network)
The inverter can be commissioned and configured from a wireless device,
such as a Smartphone, a tablet or a laptop. The commissioning procedure
is as follows:
• Supply the input voltage from the photovoltaic generator to the inverter.
• Enable the wireless functionality on the device you are using
for the commissioning of the inverter the network named
FIMER-XX-XX-XX-XX-XX-XX, where “X” is an hexadecimal number
of the MAC Address (the MAC Address is indicated on the “wireless
identification label” on the side of the inverter).
• When prompted, type the “product key” (including the dashes. Example:
1234-1234-1234-1234) as the network password.
• Open your Internet browser (recommended browsers: Chrome from v.55,
Firefox from v.50, Safari from V.10.2.1) and enter the default IP Address
to access the Configuration Wizard page: 192.168.117.1.
This will start the Configuration Wizard:
- STEP 1 - Set the Admin/User access credentials (at least 8 characters
for the password). Username and password are CASE SENSITIVE.
- STEP 2 (optional) - Enter the required information (IP Address selection
mode, SSID, and password) to connect the inverter to the wire less network.
A new message will be displayed showing the IP Address assigned by router
to access to the internal Web server. TAKE NOTE OF THE LINKS.
- STEP 3 - Set the Date, Time and Time Zone.
- STEP 4 - Set the inverter grid standard and configure the input channels.
By clicking “FINISH” the wizard completes the configuration procedure
(after the settings are confirmed, the inverter restarts).
ATTENTION –AFrom the moment the grid standard is selected,
there will be 24 hours available to make any changes to the grid
standard; after this, the “Country Select” feature is blocked and you
can make further changes only by resetting the remaining-time timer.
• Supply the grid voltage to the inverter. Once the AC and DC disconnect
switches are closed and the Configuration Wizard has completed the
configuration procedure, the inverter starts the grid connection sequence.
If the outcome of the preliminary checks is positive, the inverter will
connect to the grid and start exporting power. The “Power” LED remains
solid on, while the “Alarm” and “GFI” LEDs are off.
READ THE MANUAL –EFor more information about the configuration
and use of the internal Web server, refer to the product manual.
12. Arc fault detection
For PVS-60-TL-US-S and PVS-60-TL-US-SC models only, the AFD
performs a self-test when the system is started.
If the self-test results are OK, the inverter will continue to AC grid
connection.
If a potential problem on the AFD board is detected, the self test will
result in error E053.
Refer to the product manual (downloadable as described on the cover
page) for troubleshooting suggestions.
During normal operation the input current is continually measured and
analyzed.
If a DC arc fault is detected during operation, the inverter is disconnects
from AC grid and generates an E050 error code (readable through
internal Webserver).
Press and hold the AFD reset button on the left side of the DC wiring
box for 3 seconds. This will clear the E050 error and restart the self
test.

If self-test results are OK, the inverter will reconnect to the AC grid; if
the DC arc fault is still present, the self-test will result in error E053.
Refer to the product manual online for solutions. The AFD self-test can
be manually started anytime using the following procedure:
1. Turn off the inverter (switching off both DC and AC switches),
2. Turn on both the DC and AC switches and wait for self-test result.
WARNING –BIf the AFD trips frequently, it means arcs are occurring.
Turn the inverter OFF and request service to do complete check of
the system wiring, including all connections and junction boxes, to
locate the problem.
13. Grid support functions
The inverter is equipped with advanced grid support functionality that
is useful to support reactive loads and also assist in reliable operation
of the utility grid in the presence of a large number of distributed energy
generation sources. The grid support functions that are equipped on this
inverter are described in the following sections.
The internal Webserver can be used to adjust grid parameters. A Wi-Fi
connection to the inverter is required to modify settings using the internal
Webserver.
READ THE MANUAL –EThis QIG provides an overview of the
available grid support functions. For complete details, refer to the
product manual at www.fimer.com.
• Voltage ride-through
This inverter provides parameters to respond to undervoltage and
overvoltage events. The inverter is designed to operate normally within
the specified operating range. If voltage excursions occur, the inverter is
designed to continue operating normally or cease to export power for a
specified delay. Beyond this programmed delay, the inverter disconnects
from the grid in the event of an abnormal voltage condition.
• Frequency ride-through
This inverter provides parameters to respond to underfrequency and
overfrequency events. If frequency excursions occur, the inverter is
designed to continue operating normally for a specified delay. Beyond this
programmed delay, the inverter disconnects from the grid in the event of
an abnormal voltage condition.
• Reactive power control
The inverter provides several modes of operation for reactive power
control and are described below:
- Disable: This is the default setting. Under this setting, the inverter
exports with a power factor of 1.0.
- Fixed power factor control (Cosφ set): In this mode, the operator can set
the output power factor to a fixed value. When enabled, a new value will
be set in the inverter.
- Q Fixed (Q Set): Sets the reactive power to a fixed value. When enabled,
a new value will be set in the inverter.
- Power factor as function of output power ( Watt /Cosφ Settings: Cosφ(P)):
In this mode, the inverter reduces the power factor (cos-phi) as a function
of the output power at a given operating point. The 4 points of the default
curve, where you can set the % of Pmax values and related cos-phi, can
be modified using the internal Webserver. When enabled, the curve will
be set in the inverter.
- Dynamic Volt/VAR control (Volt/VAr Settings: Q(V)): Under this mode,
the level of reactive power exported by the inverter is a function of the
operating grid voltage, also known as a Volt/VAR curve. The 4 points of
the default curve, where you can set the % of Vnom values and related %
of Smax, can be modified using the internal Webserver. When enabled,
the curve will be set in the inverter.
• Active Power Control
This inverter offers several modes for active power reduction.
- Active Power Curtailment: Sets a new value of active power as % of
Pmax. When enabled, a new value will be set in the inverter.
- CEI Average VGrid Derating (only italian grid standard): Sets, after a
specific threshold, an active power derating based on the average of Vac
on 10 minutes as per CEI-021 italian grid standard.
- Volt/Watt settings: P(V). Under this mode, the level of active power
exported by the inverter is a function of the operating grid voltage, also
known as a Volt/Watt curve. The 4 points of the default curve, where you
can set the % of Vnom values and related % of Pmax, can be modified
using the internal Webserver. When enabled, the curve will be set in the
inverter.
- Frequency/Watt function (Frequency Control: P(f)): In this mode, the
inverter limits the active power as a function of the grid frequency.
• Ramp control
The inverter is designed to control the rate at which output power is
increased, either at startup, or after a temporary low power condition
on the PV array (such as fast shading). The following ramp controls are
provided on this inverter.
- Normal ramp: The normal ramp defines the maximum rate at which
the inverter can increase the output power under normal operation. The
normal ramp control limits the fluctuations in the output power in order to
prevent instabilities on the utility grid.
- Soft start: The soft-start ramp defines the maximum rate at which the
inverter can increase the output power when the inverter is first starting
up. This startup may occur on a daily basis or when the inverter restarts
after an abnormal grid event has ended.
14. Voltage & Frequency trip limits
This inverter has been factory programmed to automatically disconnect
from the utility distribution system in compliance with UL 1741 and IEEE
1547-2003 specifications. Default voltage and frequency trip limit and trip
time settings to comply with these standards are shown in table below. The
internal Webserver can be used to adjust Voltage and Frequency Trip Limit
and Trip Time Parameters according to Grid requirements of installation
countr y.
