The user is responsible for ensuring that a switching load of 8A /
150 VA (W) is not exceeded in the event of a fault. Internal spark
suppression by means of two zinc oxide varistors (275 V). The output
relays of the instrument (1 relay or several) may only be disengaged
in
total 5 x per minute at the most. Admissible clicks
according
to interference suppression standard EN 61000-6-4 for the industrial
sector. In case of a higher switching rate, the operator must take
care of interference suppression on the spot and under his own
responsibility by observing the load to be switched.

The electronic outputs (terminals 5, 8 and 11) are programmed by
the factory as NPN or PNP switching transistors (open collectors)
in accordance with purchase order specification. The outputs are
programmed as pulse or continuous signals in the programming
mode (lines 31, 32 and 33).

3.4 Assignment signal input
Terminals 12 to 17 are AC optocoupler inputs that may be triggered
by any PNP or NPN encoder. The required input logic can be assi-
gned at the connecting terminal by wire jumper (refer also to assi-
gning the input logic).
