Fan supply
Some power feedback units are equipped with two terminals (blue terminal =
neutral [N] , grey fuse terminal = phase [L]) for the supply of the internal
fan(s). 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 control board 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 sur-
face to the metal cable glands of the flange.
4.4.4
Control functions
The control terminal strip is placed on the control board 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 volt-
age. 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 ex-
ternal reset or the switch-functions and to connect them with the controller or
the PLC.
