7.1. Overcurrent protection
•
The unit may only be operated with the correct overcurrent protection.
•
This must be established by a qualified electrician.
•
The recommended protection is shown in the enclosed wiring diagram.
The extra-low voltage control cables must be laid separately from the mains cables.

Connection compartment / Connections on the unit
The connection compartment is located in a separate connection box outside the device. The cover
of the connection box can be opened by loosening the 4 screws (see Fig. 7). Cables that carry mains
voltage must be fastened with the tension relief devices available. Connection is as described in
Section 7.2.
Unit supply cable
Connect the mains supply cable as shown in the wiring diagram.
Suitable fuse protection should be provided.
External extraction fan
A multi-stage extract air fan can be connected to the terminal block. Terminals for the corresponding
fan stage are shown in the wiring diagram. Terminals for neutral conductor and earth conductor are
also shown in the wiring diagram. (230 VAC, max, 2A)
Valve actuator
An actuator can be connected for an air damper. Terminal assignment for opening and closing the
air dampers and connecting the neutral conductor and earth conductor (see wiring diagram). To save
energy and for electrical safety, the close signal is only active for 4 minutes after the fan has been
switched off (230 VAC, max. 1 A).
Unit malfunction
If there is a malfunction on the unit, an error message appears on the display and at the same time
switches a relay. A closing and opening signal is available (see wiring diagram). Electrical connection
of the changeover contact with U - 230 VAC and Imax = 2A.
Unit enabling
The unit can be switched on and off with an external potential-free contact (see wiring diagram). An
external voltage must never be applied to this connection. The control system would be destroyed.
Any devices that provide a potential-free contact (e.g. a time switch) can be used to control the unit.
This contact must be securely isolated from interference voltages because otherwise dangerous
conditions might occur in the event of a fault.
Control unit
The control unit is connected to the supply air unit‘s control system with a control cable. A connector
on the control cable is plugged directly into the socket on the control unit from beneath (see Fig. 10).
On the unit, the control cable is first fed through a cable gland (see Fig. 7), placed in the cable duct
and then connected to the RJ10 socket provided in the controller board. The control cable must not
be shortened. Any excess length must be stowed outside of the housing. If the cable is too short,
extensions can be ordered from the manufacturer or supplier. Alternatively, a 4-wire data cable with
120 Ohm resistance can also be connected. This is fed through the back wall of the control unit and
connected to the spring-loaded terminals. In the unit, instead of being connected to the controller
board in the RJ10 socket, the cable is connected in the spring-loaded terminals next to it (see wiring
diagram).
