CAUTION
Operation without a main contactor/circuit breaker is not permissible.
The control voltage for the main contactor (or the circuit breaker) must always be routed via
terminal XR (connections 109 and 110) of the SIMOREG unit and via terminal X_SCHÜTZ
(connections 4 and 5) of the SIMOREG CCP.
For a parallel connection (see Chapter 6.3.1) all SIMOREG units must be incorporated in this
interlock circuit.
In applications with SIMOREG CCP, in the case of a fault, the basic converter unit or the
SIMOREG CCP must be able to safely and reliably disconnect the arrangement from the line
supply.
In addition, it must be carefully observed that the total of the delay times of all of the switching
elements in the control circuit must not exceed the time set at parameter P089.
