SHOCK HAZARD FROM MULTI-CONDUCTOR CABLES
With a multi-conductor cable, the conductors that are not connected can cause an accidental contact with a conducting
component.
If a multi-conductor cable is used, cut off all conductors that are not connected.
-
The enclosure sizes FR8 and larger have the DC connection as optional.
If it is necessary to connect an external brake resistor, see VACON
Resistor
Connection.
6.2 EMC-compliant Installation
For cable selections in different EMC levels, see
For the EMC levels C1 and C2, it is necessary to have a 360º grounding of the shield on both ends of the motor cable.
