3 Product overview
3.1 Operational area
Fcontrol model series FKDM..-C are designed for a steplesss control of 3 ~ compressor motors
Constant pressure and temperature trend, caused by the continiously compressor power control,
makes energy saving at the most energy-intensive part of the refrigeration circuit possible.
With the selection program of the compressor manufacturer, it is possible to get the rated current of
the compressor in the desired operation point. These current is the deciding current for the selection
of the frequency inverter.
By operation of the compressor directly at mains, the starting current is very high. If the compressor is
driven with a frequency inverter, this current is limited by “soft-start”. A maximum starting current of
times 2 of the rated frequency inverter current is possible.
If the compressor is allowed to be driven with 60 or 87 hz, the performance can be improved clearly,
compared with 50 Hz operation. Please note the information of the compressor manufacturer.
3.2 Functional description
The frequency inverters from the FXDM..-C series generate their 3 ~ output with variable voltage and
frequency from the three-phase mains on the input. These are structured corresponding to the general
requirements in DIN EN 61800-2 for adjustable speed electrical power systems and are designed for
Single-quadrant operation.
•Reliable operation of the motor by integrated all-pole effective Sine filter (phase to phase and
phase to ground).
•No danger for the compressor motor through voltage peaks generated from the frequency inverer.
•Installation without shielded cables between frequency inverter and compressor.
•No limitation of cable length between frequency inverter and compressor.
3.3 Maintenance
The device must be checked for soiling and, if necessary, cleaned in periodic intervals.
The ventilation grilles on the bottom and on the top of the device must be free to ensure adequate
cooling of the device. They can be cleaned with a vacuum cleaner, broom or brush.
3.4 Transport
•The device is packed ex factory to suit the transport method previously agreed.
•Always use the original packaging materials when transporting the device.
•Avoid shocks and impacts to the device during the transport.
•During manual handling the human lifting and carrying restrictions must be observed and adhered
to.
3.5 Storage
•The device must be stored in its original packaging in a dry and weather-proof room.
•Avoid exposure to extreme heat and cold.
•Avoid prolonged storage; we recommend a maximum of one year (consult the manufacturer before
starting if stored for longer).

4 Mounting
4.1 General notes
Attention!
The following points must be complied with during the mechanical installation to avoid causing a defect
in the device due to assembly errors or environmental influences:
•Before installation remove the device from the packing and check for any possible shipping
damage!
•Assemble the device on a clean and stable base. Do not distort during assembly! Use the
appropriate mounting devices for proper installation of the unit!
•A mounting on vibrating base is not permissible, if no data to the vibration strength is made (
Technical data)!
•When mounted onto lightweight walls, there must be no impermissibly high vibrations or shock
loads. Any banging shut of doors that are integrated into these lightweight walls, can result in
extremely high shock loads. Therefore, we advise you to decouple the devices from the wall.
•Do not allow drilling chips, screws and other foreign bodies to reach the device interior!
•Maintain the stated minimum clearances to ensure unobstructed cooling- air feed as well as
unobstructed outgoing air discharge (
minimum space requirement)!
•The device should be installed in a location where it will not be disturbed, but at the same time can
be easily accessed!
•Care must be taken to avoid direct radiation from the sun!
•The device is designed for vertical installation (cable inlet down). A horizontal or reclined installation
is only permissible after technical release of the manufacturer!
•Be sure to observe proper heat dissipation (
Technical data, heat dissipation).
4.2 Minimum space requirement
In order to ensure sufficient ventilation of the device, clearance on all sides of at least 50 mm has to
be maintained to the housing walls, switch cabinet doors, wiring ducts, etc. The same clearance
applies to the installation of several devices next to each other.
When installing several devices on top of each other, the danger of reciprocal heating exists. This
layout is only then permissible when the air suctioned from the upper unit does not become warmer
than the permissible ambient temperature (
Technical data). I.e., a correspondingly larger clearance
or thermal shielding is required.

5.1 Safety precautions
Danger due to electric current
•Work on electric components may only be carried out by trained electricians or by persons
instructed in electricity under the supervision of an electrician in accordance with electrical
engineering regulations.
•It is forbidden to carry out work on electrically live parts. Even after disconnection, the dc-
link is still live. Always wait at least 3 minutes.
•A second person must always be present when working on energized parts or lines who
disconnects in case of emergency.
•Inspect electrical equipment periodically: retighten loose connections – immediately replace
damaged lines and cables.
•Always keep switch cabinets and all electrical supply facilities locked. Access is only
allowed for authorized persons using a key or special tool.
•Operating the device with the housing cover removed is prohibited because energized,
exposed parts are present inside the device. Disregarding this regulation can lead to severe
personal injury.
•The required protective earth connection is established using screws between the housing
parts in metal terminal space covers and housing casings. Commissioning is only permis-
sible after these screws have been properly attached!
•Metal screwed-connections are not permitted in plastic housing parts because there is no
potential equalization.
•Never clean electrical equipment with water or similar liquids.

5.3 EMC-compatible installation
5.3.1 Motor cable
The applicable standard for interference emissions is EN 61000-6-3. Compliance with this standard is
achieved through the use of an unscreened motor feed cable.
5.3.2 Control cables
Pay attention to sufficient distance from powerlines and motor wires to prevent interferences. The
control cable may not be longer than 30 m. Screened control cables must be used when the cable
length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.
only to the control unit with the protective ground (keep cable short and with as little inductance as
possible!).
5.3.3 Harmonics current and line impedance for devices > 16 A and ≤ 75 A

5.5 Residual-current-operated protective device
Danger due to electric current
For an installation of r.c.d. protection, it shall be observed that this must be of “universal-
current sensitivity” (Type B). In accordance with EN 50 178, Section. 5.2. other types of current-
operated protective devices may not be used. To ensure as high a degree of reliability as
possible , we recommend a tripping current of 300 mA.
5.6 Inverter output
5.6.1 Motor connection
The motor leads are connected to the terminals: PE, U, V, W. Comply with the motor data (rating
plate) regarding the type of connection (Y or D).
Adjustments in line with the motor in question can be carried out in “Motor Setup”.
Information
A maximum starting current of times 2 of the rated frequency inverter current is possible!
5.6.2 Disconnection between controller and motor (repair switch)
Ideally, a repair switch should be installed before the controller (supply line disconnect).
In the case of complete disconnection (entire load) after the controller, the enable (controller OFF /
ON) must be disconnected simultaneously. I.e., an additional control contact is needed. Switching on
the motor while simultaneously issuing the enable (ON) achieves secure energizing with low satura-
tion of the controller. For this a programming is necessary (
IO Setup Enable ON / OFF).
Attention!
When switching on the motor plus existing release: under certain circumstances, this can occur under
full modulation of the controller.
5.7 Motor protection
Motor protection is possible by connecting thermostats “TB” or thermistors (PTC thermistor) “TP”.
•When connecting several motors, always make sure that thremostats “TB” or thermistors “TP” are
connected in series. A maximum of six individual thermistors (DIN 44081 or DIN 44082) may be
connected in series to a single device. At least two or three single thermistors are installed depend-
ing on the motor type.
•Monitoring of motors in Ex zones is not permissible. For systems of this type, an additional posistor
tripping unit is required, with disconnection via a separate motor protection circuit.
The unit switches off when a connected thermostat or thermistor has tripped the circuit (interruption
between both terminals “TB/TP”. The unit then remains switched off. A programmed fault-indicating
relay is triggering.
Display during motor fault
Possibilities for re-starting after the drive has cooled down terminals “TB/TP” bridged by:
•By switching the mains voltage off and then on again.
•Function “Reset” Menu group “Start”
•By digital input for remote (enable ON/OFF) or by Reset-input (
IO Setup - Digital Inputs).
Attention!
•An outside voltage may never be connected to the terminals “TB/TP” and/or!
•If a bypass circuit is installed, or in the “100 %” position on devices with a main switch, the motor
protection inside the controller has no function. In this case, additional motor monitoring may be
required.

Addressing Addressing
The connections for MODBUS “A (D+)”, “B (D-)” are available double and are connected with each other internally.
Information
•You must ensure correct connection; i.e. “A (D+)” must also be connected on the following devices
to “A (D+)”. The same applies to “B (D-)”.
•In addition, a "GND" connection must be established, as dissimilar potential (over 10 V!) will lead to
the destruction of the RS-485 interface (e.g. lightning).
•Except the data link “A (D+)”, “B (D-)” and “GND” (for automatic addressing additional “ID1” - “ID2”
following chapter) no further cable cores of the data line may be used.
•Do not use wire shield.
•Pay attention to sufficient distance from powerlines and motor wires (min. 20 cm).
•A maximum of 64 members can be directly connected to one another, and another 63 members via

a repeater (only for manual addressing i.e. no connection of the terminals “ID1”,“ID2”).
Example for MODBUS connection
MODBUS
26.02.2007
v_modbus_verbindung.vsd
The data line must be conducted from one device to the
next. No other type of wiring is allowed!
Always use only two wires of one lead (twisted pair) for
the connection.
Recommended wire types
1. CAT5 / CAT7 cables
2. J-Y (St) 2x2x0.6 (telephone wire)
3. AWG22 (2x2 twisted pair)
Max allowed wire length 1000 m (CAT5/7 500 m).
When using telephone flex with four cable cores, we recommend the following allocation:
•A (D+) red
•B (D-) black
•ID1 - ID2 yellow (for automatic addressing)
•GND white
Default interface parameter
•Baudrate 19200
•Bits 8
•Parity Even
•Stop bits 1
•Handshake none
Information
•Addressing is performed by an external terminal or a PC with the appropriate software (automatic
addressing
following chapter).
•The MODBUS register description and the information sheet “Network structure of MODBUS” can
be requested from our Support Department V-STE for control systems - ventilation.

5.14.2 Automatic addressing
Automatic addressing can be performed by a PC with ZAset software. The connections “ID1” and
“ID2” for “addressing” are connected with each other additionally next to the bus connection for this.
This means that it is no longer necessary to address every single member manually in the network.
On the first client that is connected directly to the terminal or the PC, “GND” and “ID1” or “ID2” must be
bridged. This is recognised as a result and occupied by address 1.
For the following clients the connection “ID1” or “ID2” of a client respectively is connected with
connection “ID1” or “ID2” of the next client.
The automatic addressing of other clients is initiated by the previous client via this connection.

Information
•Except the data link “A (D+)”, “B (D-)” the “ID1 - ID2” and the “GND” connection may no further cable
cores of the data line be used.
•The connections for the automatic addressing “ID1” and “ID2” are not directly connected with each
other internally. These may not be bridged; any order of connection is possible.
•When using the automatic addressing, no repeaters can be used because these do not pass the
signal through to the addressing.
5.15 USB-interface
Over the USB interface if necessary a software update can be made. For this a consultation with our
V-STE support department for control systems-ventilation technology is necessary.
For communication with a PC (Virtual COMM Port) we make the necessary programs available on
request.
Danger due to electric current
Plug the jumper J1 to both PINs only for a software update via USB interface. The device will not
switch on if this jumper is plugged to both PINs!
Do not replug the jumper under voltage, observe the safety instructions!

5.16 Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
protective earth. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50 V (between “GND” terminals and “PE” protective earth). If necessary, a
connection to the protective earth potential can be established, install bridge between “GND” terminal
and the “PE” connection (terminal for screening).
5.17 Bypass circuit
Please observe the following during bypass switching (controller shunt with mains voltage):
•Mutual locking of mains contactor and bypass protection
•Time delay of at least 1 second during switching
•The controller “enable” (ON / OFF) must be simultaneously opened together with cut-off of the
protection on the controller output; during connection it must be simultaneously closed again. For
this a programming is necessary (
IO Setup Enable ON / OFF).
•By switching OFF necessary waiting period before renewed switching on amounts minimum
90 seconds! (
connection suggestion for bypass with the required time-delay)
•Never apply line voltage to the inverter output!
5.18 Manual Bypass-Switch type S-D-25 and S-D-50
As accessories are manual main switches with bypass function available.
By switching OFF Frequency inverters necessary waiting period before renewed switching on
amounts minimum 90 seconds!
