Fan supply
All devices are equipped with two additional terminals at the connection plate of the
feedback unit for the supply of the fan. The fuse inside the fuse terminal is installed for
internal wire protection and of the following type
2A medium 500V 5x30mm
.

Control wires
•
Connect the control wires to the terminal row X2 at the connection plate of the
power feedback unit.
•
Don’t parallel control wires to interfering power wires.
•
Connect the screening of the control wires with an as big as possible surface to the
metal cable glands of the flange.
4.4.4
Control functions
The control terminal strip is placed on the connection plate and is indicated with X2. It
is fitted with a plug-in device for easy handling (see figure 4.4.4.2).
The control board must always be designed for the respective main circuit voltage.
Therefore the main circuit voltage (230 V, 380 V - 415 V, 440 V - 480 V, 500 V or 690
V) must be declared with every order. This is also necessary for a possible exchange of
the device.
From the control terminal strip the operating condition or rather the collective error can
be connected to extern. There is also the possibility to execute the external reset or the
switch- functions and to connect them with the controller or the PLC.
