ELECTRICAL CONNECTION
WARNING!
An incorrect system voltage can damage the unit. When estab-
lishing electrical connection, ensure that the system voltage cor-
responds to the voltage specified on the rating plate!
NOTE!
For the erection of power installations with rated voltages up to
1000 V, the requirements of VDE 0100 and relevant standards and
specifications must be observed! The supply circuit of the unit
must be provided with a fuse of 16AT (overcurrent protection); the
electrical values are shown in the technical data.
Electrical connection can take place after removal of the front cover as shown in the diagram below on
the internal terminal strip. The cover can be removed by loosening the four screws visible on the front
cover. Provided on the underside of the housing are four PG 13.5 glands through which the cables can
be inserted as shown in Figure 3. Figure 3 shows the electrical wiring diagram for the controller type
70304G
