Switching examples
Direct connection 230 V/400 V to 5 A
The monitoring logic checks internal relay contacts (not shown)
to see whether both relays have been released prior to switching
on. This ensures that no contacts are welded. The voltage level
at terminal A1 is also monitored. The parallel NC contacts K1
and K2 (terminals 41 and 42) can be connected as required.
Connection of external contactors
External contactors may be used when they are equipped with
positively driven contacts according to safety regulations
ZH1/457 of the German Trade Association. Contactors with
3 NO contacts and 1 NC contact must be used, whereby the
NC contacts must be integrated in the monitoring loop –
terminals Y1/Y2. The parallel NC contacts K1 and K2
( terminals 41 and 42) can be connected as required.
