Attention
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 order 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.
WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!

WARNING
Risk of injury through electric shock and damage to the device!
Bring the Bus Terminal system into a safe, de-energized state before starting mounting,
disassembly or wiring of the Bus Terminals!
