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).
Separate supply of the control
Without further cooling measure a separate supply of the control is not permissible
during a longer period, because the interior fan is not controlled here. The occuring
heat accumulation causes an accelerated aging of the capacitors and thus for a
reduction of the economic life time.
