Example: injection exclusion with two incoming feeders and one coupling

The coupling is closed

The same applies as in the example for injection exclusion with two incoming feeders. See Example: injection exclusion with two incoming feeders for example of injection exclusion with two incoming feeders.

The coupling is open:

• D1 is closed AND

• D2 is closed

Both devices are active:

• Device no.1 monitors the insulation of system 1,

• Device no.2 monitors the insulation of system 2.
