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
To comply with the EMC levels, use a grommet when installing the motor cable at the two ends. For the EMC levels C1 and C2, it is
necessary to have a 360º grounding of the shield with grommets in the motor end.

Cable
Category C1 and C2
type
Motor ca- A symmetrical power cable with a compact low-im-
ble pedance shield.
A cable for the specified mains voltage.
We recommend an NKCABLES /MCCMK, SAB/
ÖZCUY-J or equivalent cable. See
Mains ca- A power cable for a fixed installation.
ble
A cable for the specified mains voltage.
A shielded cable is not necessary.
We recommend an NKCABLES/MCMK cable.
