Building and Installing Cables

Knowledgeable cable routing and careful cable construction improves
system ElectroMagnetic Compatibility (EMC).

To build and install cables, perform the following steps:

1. Keep wire lengths as short as physically possible.

2. Route signal cables (encoder, serial, analog) away from motor and

power wiring.

3. Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel

run.

4. Ground both ends of the encoder cable shield and twist the signal wire

pairs to prevent electromagnetic interference (EMI) from other
equipment.

ATTENTION

High voltage can be present on the shield of a
power cable, if the shield is not grounded.

Ensure there is a connection to ground for any
power cable shield.

Failure to observe these safety procedures could
result in personal injury or damage to equipment.
