ential current re-
lease
Do as follows to test that the differential current release is responding correctly:
The generator is running.
1. Move the main switch into POS I.
2. Press the differential current release test switch.
The circuit breaker position shows the test result.
The device has been tested in compliance with DIN VDE 0100-551.

from the generator again.
In “building supply” mode, the white feed socket (Fig. 7-3 Connecting consum-
ers) is secured against overload and short circuit by the main switch. The inte-
grated differential current release is only for protecting the system. Due to its
electrical design, it offers NO PERSONAL PROTECTION! For this, be sure to
follow the instructions in Chapter 8.2 .
