Connecting and mounting the RMD cutoff relay
Mount the cutoff relay only in distribution boxes or in control cabinets on a 35 mm DIN top
hat rail.
Figure 4
Connect cutoff relay according to connection diagram (Figure 4).
The cutoff relay is connected and ready for operation.
Installing master control with more than 2drives
In order to activate more than two drives at the same time, several cutoff relays have to be
connected in parallel.
The max. number of drives to be controlled in an electric circuit depends on the load limit of
the upstream circuit breaker.
Observe current consumption of the individual drives.
When more than 8 drives are connected, distribute load to several circuit breakers. Ensure
that connections are in phase.
Connect cutoff relay according to connection diagram (Figure 3 (10) and Figure 4 (13)).
