When connecting several PWEAAC/AP units to a single 24 VDC source:
ensure the same polarity for the terminals KL4.5 and KL4.6.
There is no galvanic isolation between the terminals KL4.1 … 6 and the condens
ate area.
•
At 24 VDC operation: do not c (plus) 24 VDC to ground as, inside the
device, the potential of the housing is negative.
