Routing the Power and Signal Cables

Be aware that when you route power and signal wiring on a machine or system,
radiated noise from nearby relays, transformers, and other electronic devices can
be induced into I/O communication, or other sensitive low voltage signals. This
can cause system faults and communication anomalies.

The hybrid cables and network cables are UL listed with 1000V and 105

°

C

(221

°

F) insulation ratings, and can be routed in a common wireway.

Refer to

Electrical Noise Reduction

on

page 27

for examples of routing high and

low voltage cables in wireways. Refer to the System Design for Control of
Electrical Noise Reference Manual, publication

GMC-RM001

, for more

information.

Grounding the IDM System

All equipment and components of a machine or process system should have a
common earth ground point connected to chassis. A grounded system provides a
ground path for short circuit protection. Grounding your modules and panels
minimize shock hazard to personnel and damage to equipment caused by short
circuits, transient overvoltages, and accidental connection of energized
conductors to the equipment chassis.

IMPORTANT

IDM system wiring differs from common PWM servo system wiring
configurations in the following ways:

Hybrid and network cables can be tie-wrapped together and occupy the

same cable run

Hybrid and network cables do not require physical segregation as a result

of more effective wire shielding and improved grounding techniques.

This exception applies only to the hybrid and network cables that connect to an
IPIM module or between IDM units, and does not apply to cabling elsewhere in
a Kinetix drive system. Refer to the System Design for Control of Electrical Noise
Reference Manual, publication

GMC-RM001

, for more information.

National Electrical Code, local electrical codes, special operating temperature,
duty cycles, or system configurations take precedence over the information
presented above and the values and methods provided in the document
referenced above.

ATTENTION: The National Electrical Code contains grounding requirements,
conventions, and definitions. Follow all applicable local codes and regulations
to safely ground your system.

For CE grounding requirements, refer to

Agency Compliance

on

page 19

.

ATTENTION: High voltage can buildup on the shields of a hybrid cable, if the
shield is not grounded. Verify that there is a connection to ground for all shields
in the hybrid cable. Failure to observe these safety procedures could result in
personal injury or damage to equipment.
