INSTALLATION ENVIRONMENT
The CPS and the Battery Cabinet must be installed in ventilated, clean environments which are sheltered from bad weather.
The ambient temperature and relative humidity must not exceed the maximum values shown in the "TECHNICAL DATA” table.
Avoid installation in locations exposed to direct sunlight or hot air.
The recommended operating temperature for the product with the batteries is between 20 and 25°C.
Warning: an ambient temperature increase of 10 degrees will half the batteries expected life.
The CPS of category C2 if installed in a residential environment may cause radio interference, in which case
the user may be required to take additional measures.
For three-phase installation, this equipment complies with IEC 61000-3-12 provided that the short-circuit power
Ssc is greater than or equal to 2.94MW (7.4kA) at the interface point between the user's supply and the public
system. It is responsibility of the installer or the user to ensure that the equipment is connected to a supply with
the adequate short-circuit power Ssc (if required, consult the distribution network operator).
If the supply doesn’t meet the above requirements or if the requirements listed above are difficult to obtain, a
single-phase installation is suggested.
PLACEMENT
When installing the equipment, the following points should be considered:
 the wheels are to be used exclusively for fine positioning, and thus for small distances only.
 the plastic parts and the front panel are not to be used for gripping or pushing.
 enough space should be left in front of the equipment for it to be turned on/off and maintenance operations to be
performed on it (1.5 m)
 the rear part should be set at least 30 cm from the wall, to enable the air blown by the ventilation fans to flow away
correctly and to allow access to the disconnector switches
 no objects should be left on its top surface
 check that the room containing the batteries is ventilated in compliance with EN 50272-2 paragraph 8.2

POWER CONNECTION
ATTENTION: BEFORE PROCEDING WITH THE FOLLOWING OPERATIONS, MAKE SURE THAT THE CPS
IS COMPLETELY OFF AND DISCONNECTED FROM THE MAINS AND ANY LOAD.
ALL OPERATIONS DESCRIBED IN THIS SECTION MUST BE PERFORMED BY QUALIFIED PERSONNEL
ONLY. Our Company assumes no liability for damages caused by incorrect connections or operations
not contained in this manual.
The CPS and the Battery Cabinet contains HAZARDOUS electrical voltages inside them, even when the
input and/or battery switches are off. The internal parts are protected by safety panels which can be
removed by trained personnel only. All installation and maintenance or operations involving access
inside the CPS or Battery Cabinet require the use of tools and may ONLY be performed by trained
personnel.
To carry out the following operations, the CPS must be disconnected from the mains power supply,
switched off, and with all the equipment switches and fuse holders open. Check that there are no Battery
Cabinets connected to the CPS, if this is the case open all their fuse holders.
INSTRUCTIONS FOR CONNECTION
Follow the instruction below to access the terminals of the CPS and made the electrical connections:
1. Remove the terminals cover in the back of the CPS,
placed below the disconnector switches (see "CPS
VIEWS")
2. Pierce the rubber grommets to allow the wires to
pass through, otherwise remove the pre-cut slots
(located in the bottom part of the terminal cover)
using cutters.
3. We recommend using double-insulated multi-core
cables to be connected, respectively, to the “INPUT”
and “OUTPUT”.
4. For the cross section and the cable stripping, refer
to the paragraph "CONNECTION CABLES CROSS
SECTION DETAILS
5. The wires should be stripped and inserted into the
terminals (for the length of the stripping, refer to the
paragraph “CONNECTION CABLES CROSS SECTION
DETAILS”).
NOTE: To remove the wire, insert a flat blade
screwdriver into the clamp slot above the wire inlet.
6. Fix the cables to the ties block in the back of the
CPS.
7. When the installation is complete, close the
terminals cover and secure with the screws
Option with cable glands (not supplied):
Cable glands (not supplied) can be used to secure the cables, using the pre-cut holes in the terminal cover; refer to the example
images below. To remove the pre-cut disks use a suitable pair of cutters.

INTERNAL PROTECTION
Within the cabinet there are fuses (not accessible) in order to protect the rectifier input stage, the output stage of the inverter
and the batteries. The table below shows the values of the internal protection fuses.
NOTE: the CPS internal bypass line is not protected by fuses. We recommend installing an external protection device as
defined in the chapter “EXTERNAL PROTECTION DEVICES”.
Internal protective devices
Model Input fuses Battery fuses Output fuses
3 kVA 2 x 25A GF (6.3x32) 80A aR 2 x 25A GF (6.3x32)
5 kVA 2 x 25A GF (6.3x32) 80A aR 2 x 25A GF (6.3x32)
WARNING: To insulate the CPS from the D.C. supply, disconnect all of the Battery Cabinets (if present).
SHORT CIRCUIT
If a fault occurs on the load, the CPS protects itself by limiting the value and the duration of the current supplied (short circuit
current). The short circuit current value is related to the CPS operating status at the time of the fault, these can either be (in
the "TECHNICAL DATA” table the protection characteristics and timings are described):
 CPS in NORMAL OPERATION with the Bypass Line available: the load is switched instantaneously to the bypass
line: the input line is connected to the output without any internal protection.
 CPS in BATTERY OPERATION or in NORMAL OPERATION but with no Bypass Line available: the CPS protects
itself by providing a higher current than the nominal one (see paragraph “TECHNICAL DATA”) and turns itself off after
this time has elapsed.
NOTE FOR SELECTIVITY: if the load is made up of more than one device, to avoid the opening of the protective devices
upstream of the CPS due to a failure of a single piece of equipment, it is recommended to protect each output line with a
suitably rated thermal or magnetothermal protection device. The maximum value for the protective device of each single line
must be lower than the current threshold of the protection upstream of the CPS and lower than the current supplied by the CPS
with the inverter on.
BACKFEED
The CPS has internal protection against backfeed, however the label supplied with the CPS must be affixed to all disconnectors
installed within the electrical system upstream of the CPS.

EXTERNAL PROTECTIVE DEVICES
LINE PROTECTION: MAGNETOTHERMAL OR FUSE
Within the CPS there are protection devices for output and internal faults.
You must protect the input line (and the separate bypass line if present) with the appropriate protection devices. These devices
must comply with the regulations of the country where the CPS is installed.
In order to set up the power line, install a magnetothermal switch upstream from the CPS with intervention curve C or D
(breaking capacity ≥6kA) or gR type fuse. Please follow the indications in the table below:
Automatic external protective devices
Model Mains single-phase input (1P+N)
3 kVA 20A (Max 40A)
5 kVA 32A (Max 40A)
SAFETY DEVICES: DIFFERENTIAL
The CPS can cause a D.C. current in the PE conductor.
An RCD located upstream is suggested: its trip current should be the sum of CPS + Load leakage current, with a
suitable margin to prevent unwanted interventions.
Only a RCD Type B is allowed.
CONNECTION CABLES CROSS SECTION DETAILS
To determine the minimum cross section of the input and output cables, see the table below:
Cross section of cables (sqmm) *
Model
INPUT OUTPUT
N L N L
3 kVA 10 4 (10 max) 4 (10 max)
5 kVA 10 6 (10 max) 6 (10 max)
* The cross sections indicated in the table refer to a maximum length of 10 meters.
The cross sections refer to bare cables (without terminals).
Note: the length of the cable stripping must be equal to 15mm

- 17 -
CONNECTIONS
The first wire to be connected is the protective earth wire, which is to be inserted in the terminal marked
PE. During operation the CPS must be connected to the earthing system
Connect the cables to the terminals following the information provided on the label placed upon the CPS. In the images below
there are some notes in relation to the installation:
Models 3-5 kVA
NOTE
1. If an "external manual bypass" is not provided, make sure that there is a jumper between terminals 1 - 2 (Switch bypass).
2. The maximum cross section of the cables that may be inserted in the terminal board 1, 2, 3 & 4 are:
- 2.5 sqmm for bare cables
- 1.5 sqmm for cables with lugs.
The stripping length is 8 mm
WARNING! Pay attention to connect the input neutral (NIN) and output neutral (NOUT); incorrect connection could
cause a failure of the load when the Maintenance Bypass switch is closed.
OTHER INSTALLATION MODES

BATTERY CABINET INSTALLATION
ATTENTION:
REFER TO THE CPS SPECIFICATION LABEL TO CONFIRM THAT THE VOLTAGE FROM THE BATTERY
CABINET IS THE SAME AS THAT ALLOWED BY THE CPS.
CONFIRM THAT THE BATTERY CABINET IS EQUIPPED WITH A 50A gR FUSE TO PROTECT THE
BATTERY EXPANSION PORT OF THE CPS.
THE CONNECTION BETWEEN THE CPS AND THE BATTERY CABINET MUST BE MADE WITH THE
BATTERY CABINET FUSE HOLDER ISOLATOR OPEN.
CONNECT THE CABLE BETWEEN THE CPS AND THE BATTERY CABINET. CLOSE THE FUSE HOLDER
ISOLATORS ONLY IF THE CPS IS POWERRED ON OR IN STAND-BY CONDITION.
Battery Cabinets can be installed in series for extended runtimes. Connect the Battery Cabinets in series as shown in the figure
below:
CPS –BATTERY CABINET CONNECTION
ATTENTION:
The CPS is not equipped with devices for the disconnection of the external batteries. Verify that the Battery
Cabinets are fitted with a suitable fuse and/or fuse disconnector.
To prevent damage occurring to the batteries, the fuse holders must only be closed if the battery voltages between
the CPS and the Battery Cabinet are similar. Otherwise, recharge each battery unit following the procedure below:
CONFIGURING THE RATED BATTERY CAPACITY
Before installing one or more Battery Cabinets, the CPS must be configured in order to update the rated capacity value (total
Ah CPS's internal batteries + external batteries) using the dedicated configuration software.
The Battery Cabinet must only be installed while the CPS is switched off and disconnected from the mains power supply.
CAUTION:
The connection cables cannot be extended by the user.
The maximum length of the connecting cables between the CPS (without internal batteries) and the Battery
Cabinet is 3 meters.
After connecting the CPS to its Battery Cabinets, insert the fuses and close the Battery Cabinet battery fuse
holders (SWBATT). Do not open the SWBATT fuses whilst the CPS is on.
It is recommended that you do not connect more than 5 Battery Cabinets in cascade to a single CPS. To increase
capacity, we recommend installing a Battery Cabinet with higher battery capacity.
