Operating Guide
RISK OF DAMAGE TO THE DRIVE
Connecting the brake resistor between the terminals B- and B+ damages the drive.
-
Connect the brake resistor to the brake resistor terminals R- and R+.

6.2 EMC-compliant Installation

For cable selections in different EMC levels, see
The output cables to the motor must be 360º EMC grounded. The EMC grounding clamps can, for instance, be installed on the
mounting plate in front of the AC choke. The EMC grounding clamps must be suited to the output cable diameter to give a 360º
contact with the cables.

Cable
type
Motor A symmetrical power cable
cable with a compact low-impe-
dance shield.
A cable for the specified
mains voltage.
We recommend DRAKA NK
CABLES - MCCMK or similar.
Mains A power cable for a fixed installation.
cable
A cable for the specified mains voltage.
A shielded cable is not necessary.
We recommend DRAKA NK CABLES - MCMK or similar.
Control A shielded cable with a compact low-impedance shield, for example, DRAKA NK CABLES - JAMAK, SAB/ÖZCuY-O, or
cable similar.

For the definitions of EMC protection levels, see IEC/EN 61800-3 + A1.
In all the enclosure sizes, to comply with the EMC standards, use the default values of the switching frequencies.
When using a safety switch, make sure that the EMC protection continues from the start of the cables until their ends.
The drive must obey the standard IEC 61000-3-12. To obey it, the short circuit power S
interface point between mains and the public mains. Make sure to connect the drive and the motor to mains with a short circuit
power S that is a minimum of 120 R

6.3 Grounding

Ground the AC drive in accordance with applicable standards and directives.
DAMAGE TO THE AC DRIVE FROM INSUFFICIENT GROUNDING
Not using a grounding conductor can damage the drive.
-
Make sure that the AC drive is always grounded with a grounding conductor that is connected to the grounding terminal
that is identified with the PE symbol.
