When checking the order number of the relay plug-in unit, be careful
not to lift the handle more than 25º (approx. 40 mm). Lifting the handle
any further detaches the plug-in unit from the case.

Detaching and installing the plug-in unit
Before detaching the plug-in unit from the case, the auxiliary voltage
must be disconnected.
To detach the plug-in unit:
1. Lift the lower handle until the spring-loaded locks on both sides of the handle are
released and the unit is pushed about 6 mm out of the case. This separates the
connectors.
2. Pull the unit out of the case.
Signal connectors are left open when the plug-in unit is detached.
