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!
•Depending on the housing model cut off necessary cable inlets respectively to the cable diameter.
Or alternative use cable inlet for cable glands. Metal sheet housings are supplied with stoppers.
Any cable ducts openings not used must be sealed!
•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.
4.3 Outdoor installation
Outdoor installation is possible up to -20 °C when the controller supply is not switched off. Installation
must be protected from the effects of weather as much as possible, including protection from direct
sunlight!
4.4 Installation location for agriculture
In order to avoid damage caused by ammoniac vapours, the controller shall not be installed in the
stable, but rather in an outhouse wherever possible.
4.5 Temperature influences during commissioning
Avoid condensation in the controller and functional faults attributable to condensation by storing the
controller at room temperature!

Exception: All-current-sensitive fault current circuit breaker on the 3 ~ 230 V line
When connecting the device between two outer conductors, “all-current-sensitive” fault current circuit
breakers must be used (
EN 50 178, Art. 5.2).
5.5 Inverter output
5.5.1 Motor connection
The motor leads are connected to the terminals: U1, U2. Several fans can be connected to the
controller-the maximum total current of all motors must not exceed the current rating for the controller.
Change direction of rotation
wiring diagram fan!
Information
•It is recommended that a separate motor protection unit be foreseen for each fan.
•For motors with thermistors “TB” e.g. type S-ET10.
5.5.2 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
saturation of the controller.
Attention!
When switching on the motor plus existing release: under certain circumstances, this can occur under
full modulation of the controller.

5.6 Motor protection
The motor can be protected by connecting thermostats “TB”.
When multiple motors are connected, it is essential to ensure that thermostats “TB” are always
connected in series.
If a connected thermostat is tripped (break between the two terminals “TB”), the device is switched off
and is not switched back on.
Relais “K2” is de-energized, terminals “21” - “22” bridged. The signal lamp flashes in code
| 2 | (
Diagnostics / faults).
Possibilities for re-starting after the drive has cooled down (terminals “TB” bridged) by:
•By switching the mains voltage off and then on again.
•Via a digital input for remote control (ON / OFF enable).
Danger due to electric current
An outside voltage may never be connected to the terminals “TB”!
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.
5.7 Analog input “E1” for setting fan speed
The device has an analog input for setting the fan speed. Connection “E1” / “GND” (Analog In 1).
Danger due to electric current
•Make sure the signal has the correct polarity!
•Never apply line voltage to analog inputs!

Electronic disconnection and Reset after motor fault via floating contact at terminals “D1” - “D1”
•Device “ON” for closed contact.
•Controller “OFF” with opened contact.
Activation via floating contacts, a low voltage of approx. 24 V DC is connected.
Danger due to electric current
•No disconnection (isolation) when turned off by remote, in accordance with VBG4 §6)!
•Never apply line voltage to the digital input!
5.10 Relay outputs (K2)
An operating message or activation of a damper control motor is possible via the potential-free
contacts of the relay “K2” (max. contact load
technical data and connection diagram).
At a modulation above 5 Hz the relay energizes, i.e. the terminals “21” and “24” are bridged.
At low modulation (below 3 Hz), switch off by the enable, switch off of line voltage or in case of a fault,
the relay de-energizes.
5.11 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.
•When the contactor is switched off at the inverter output, the “enable” (ON / OFF) must also be
opened and closed again when it is switched back on. When switching off, wait at least 90 seconds
before switching back on!
•Never apply line voltage to the inverter output!
5.12 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).

Temperature management active
The device has an active temperature
management to protect it from damage
due to too high inside temperatures. In
case of a temperature rise above the
fixed limits, the modulation is reduced lin-
early. To prevent the complete system
being switched off externally (in this oper-
ation permissible for the controller) in
case of reduced operation due to too high
an internal temperature, no fault message
is sent via the relay.
With a drop in temperature the modula-
tion rises again llinear.
Check cooling of the controller
