Relay Output - Danfoss VLT 380-500 V Design Manual

Control Wiring
•
Connect a large surface of the shield to ground,
for example with a cable clamp or a conductive
cable gland.
•
Maintain the same ground potential throughout
the network by applying potential-equalizing
cables.
•
Prevent impedance mismatch by using the same
type of cable throughout the entire network.

12.3 Relay Output

The relay terminal is on the top plate of the drive module.
Connect the relay terminal of drive module 1 (the drive
module on the far left) to the terminal blocks on the
control shelf using an extended wiring harness.
NOTICE
For reference, drive modules are numbered from left to
right.
