Warning
Disconnect servomotor from mains before
removing the cover.
Observe the local safety regulations.
Protect unused screwings, cable connections and
plugs against corrosion and moisture with suitable
caps.
Caution
To ensure electromagnetic compatibility (EMC) signal
lines must be shielded, and guided in different cable
channels than mains cables.
The shield must be connected to PE or ground on the
side of the counterpart.
Caution
Before connecting the mains cable check, if the
mains voltage indicated on the type plate
corresponds to the local mains voltage. Wrong
voltage can lead to damages of the servomotor.
Note
Depending on the optional components selected,
connect mains plug to mains directly or via the
terminal box.
