Live parts
Touching live parts leads to a life-endangering electric shock. Observe the Five Safety Rules:
⇨ Isolate.
⇨ Secure against reclosing.
⇨ Verify safe isolation from supply.
⇨ Earth and short-circuit.
⇨ Cover or barrier adjacent live parts
To remove the cable compartment cover, the associated feeder must be earthed.
Unbolted cable compartment cover
In certain panels, the cable compartment cover is bolted on additionally. If the cable
compartment cover is not bolted on, the panels lose their resistance to internal faults. This
can cause death or serious injury due to an internal arc.
⇨ Always screw on the corresponding cable compartment covers additionally after
mounting the cable compartment cover.
