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 inuences:
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 sufcient 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 inuences during commissioning
Avoid condensation in the controller and functional faults attributable to condensation by storing the controller at room temperature!
5 Electrical installation
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 disconnection, 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 – 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.
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 tted 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 sufcient 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 Mains connection
5.3.1 Line voltage
Power from the mains is connected to terminals: PE, L1 and N. Here, it must be strictly observed that the mains voltage lies within the allowable tolerance specications (
Technical data and nameplate afxed to the side). A connection between two phase conductors is possible for 3 ~ 230 V supply networks.

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.
5.5.3 U/f-characteristic curve
A control signal for setting the output frequency is switched to the analog input of the device by the 5­step switch (0 - 10 V
0 - 50 Hz).

Potentiometer for step adaptation
The device operates with the respective possible maximum frequency (
diagram) in every step in the as-delivered state. The setting signal (0 - 10 V) for every step and thus the output frequency can be reduced with the internal potentiometer. The reduction acts on all steps (1 – 5) in percentage relation. It might therefore be possible to prevents interference noises caused by resonances at certain frequencies.
Potemtiometer adjustable with a screwdriver
Left stop: No reduction, i.e. output frequency e.g. in step 5 = 50 Hz (factory setting
diagram)
Right stop: Maximum reduction 25 %, i.e. output frequency, e.g. in step 5 =
37.5 Hz)
The value of the output frequency can be checked with a suitable measuring instrument!

Danger due to electric current
It is generally forbidden to carry out work on electrical live parts. Protection class of the device when open is IP00! It is possible to touch hazardous voltages directly.
The device must have been disconnected from the line voltage for at least 3 minutes before opening!
Observe the safety information!
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.

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.

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!
5.8 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.
5.9 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!
5.10 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 xed limits, the modulation is reduced lin­early. To prevent the complete system being switched off externally (in this oper­ation 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 modula­tion rises again llinear.
Check cooling of the controller
