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!

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.
•The 5 electrical safety rules must be observed!
•It is forbidden to carry out work on electrically live parts. Even after disconnec-
tion, the dc-link is still live. Always wait at least 3 minutes.
•Other measures may be necessary to achieve safe electrical isolation.
•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 – imme-
diately 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 regu-
lation can lead to severe personal injury.
•For metal cable inlets the necessary protective earth connection to the bottom
of the housing is made by screws. The device may only be started up when
these screws are fitted properly.
•The device owner is responsible for the EMC of the entire plant according to the
locally applicable standards.
•Never clean electrical equipment with water or similar liquids.
Information
The respective connections are represented in the enclosure of this manual (
Connection diagram)!
5.2 EMC-compatible installation
5.2.1 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.
5.2.2 Control cables
Pay attention to sufficient distance from powerlines and motor wires to prevent interfer-
ences. 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!).

5.2.3 Harmonics current for devices ≤ 16 A
According to EN 61000-3-2 these devices are to be classified as “professional” devices.
The application is therefore limited to use by trade, certain vocations or industries.
Connection to a low voltage supply (public networks) is allowed insofar as this has been
clarified with the respective energy supply company responsible.
5.3 Mains connection
5.3.1 Line voltage
Power from the mains is connected to terminals: PE, L1, L2, L3. Here, it must be strictly
observed that the mains voltage lies within the allowable tolerance specifications (
Technical data and nameplate affixed to the side).
Danger due to electric current
Not suitable for IT system!
5.3.2 Required quality attributes for the mains voltage
Danger due to electric current
The mains voltage must comply with the EN 50160 quality characteristics and the
defined standard voltages in IEC 60038!
5.3.3 Leakage current, securely attached, protective earth conductor
Danger due to electric current
The maximum leakage current depends on the type of device and the connected
mains voltage (
Technical Data). With regard to fixed connection and the type of
PE conductor connection, the specification for the leakage current must be ob-
served under consideration of the locally valid standards (for Europe
EN 50178
Section 5.2.11 or 5.3.2.1 etc.).
Minimum cross-section for PE conductor for fixed connection 1.5 mm

!
5.4 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.

5.5 Inverter output
5.5.1 Motor connection
The motor leads are connected to the terminals: PE, U, V, W. Several fans can be
connected to the controller-the maximum total current of all motors must not exceed the
current rating for the controller.
Information
•It is recommended that a separate motor protection unit be foreseen for each fan.
•For motors with thermistors “TP” (PTC thermistor) e.g. type U-EK230E
•For motors with thermostats “TB” (thermal contacts) e.g. type STDT16 or AWE-SK (
Enclosure: Circuit suggestion for several motors with motor protection unit type
STDT.)
5.5.2 Disconnection between controller and motor (repair switch)
Ideally, a repair switch should be installed before the controller (supply line discon-
nect).
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.

5.9 Voltage supply for external devices (+24V, GND)
A voltage supply is integrated for external devices e. g. a sensor (max. current load
technical data).
In case of overload or short circuit (24 V – GND), the external power supply is shut down
(multi-fuse). The device performs a “Reset” and continues operation.
It is not permissible to connect outputs of several devices to each other!
5.10 Enable, Device ON / OFF (Digital In 1 D1)
Electronic disconnection and Reset after motor fault via floating contact at terminals
“D1”- “24V” (input resistance and voltage range
Technical data).
•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!
5.11 Relay outputs (K1)
An operating message or activation of a damper control motor is possible via the
potential-free contacts of the relay “K1” (max. contact load
technical data and
connection diagram).
At a modulation above 5 Hz the relay energizes, i.e. the terminals “13” and “14” 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.
5.12 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!
5.13 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).

Active temperature manage-
ment
The device has an active temper-
ature management to protect it
from damage due to too high in-
side temperatures. In case of a
temperature rise above the fixed
limits, the modulation is reduced
linearly. To prevent the complete
system being switched off exter-
nally (in this operation permissible
for the controller) in case of re-
duced operation due to too high an
internal temperature, no fault mes-
sage is sent via the relay.
With a drop in temperature the
modulation rises again llinear.
Check cooling of the controller
