Connection of power circuit
3.3.1 Wiring instructions
Absolutely observe the connecting voltage of the KEB COMBIVERT. A 230V-
unit will be immediately destructed on a 400V-power supply.
Never exchange the mains and motor cables.
Some countries demand that the PE-terminal is directly connected to the
terminal box (not over the mounting plate).
