Applying the 24V operating voltage

CAUTION
Please observe the polarity when the opera-
ting voltage is applied. Connect the earthing to
pin 4, PE.
The following diagram shows the pin assignment
of the operating voltage connection. A suitable
24V DC supply should be connected via the
mains connection socket (see Chapter 3, Techni-
cal specifications). Please see also the example
of connection in Fig. 4/21.
