Possible damage of the device

Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the

mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g.

disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230 V).

For insulation testing, disconnect the PE supply line at the Bus Coupler or the Power Feed Terminal! In or-

der to decouple further feed points for testing, these Power Feed Terminals can be released and pulled at

least 10 mm from the group of terminals.

Risk of electric shock!

The PE power contact must not be used for other potentials!
