Install Cables
Follow these steps when installing a cable.
1. Provide the recommended installation areas, and the correct offset from features, before
beginning any cable bend.
Features include these areas on the cable:
•
Connectors
•
Transitions from exposed wire to insulation (for example, flying leads)
•
Exposed cable ground shields
The offset from these areas should be greater than or equal to (>1x) the cable diameter.
2. Keep cable bends within the bend radius listed in the
.
General guidelines for the bend radius of a cable are listed below, however, individual
cables may have additional restrictions:
•
Standard cables have a static or one-time bend radius of 10 times (<10x) the cable
diameter.
•
Continuous-flex cables have an operational bend radius of 12 times (<12x) the cable
diameter.
ATTENTION: Do not tightly gather or coil the excess length of a power cable. Heat
is generated within a cable whenever power is applied. Always position a power
cable so it may freely dissipate any heat.
A power cable should not be coiled, except for temporary use when building or
testing a machine. If you temporarily coil a power cable, you must also derate the
cable to meet local code or follow an authoritative directive, such as Engineering
Section 310.15(C) of the NEC Handbook.
Failure to observe these safety procedures could result in personal injury or
equipment damage.
ATTENTION: The examples in this publication show the available connections,
some of which may not be appropriate for your specific installation. Refer to your
drive installation instructions or user manual for recommended wire trim lengths,
and wiring examples appropriate to your drive and motor application.
Do not connect unused wires. Unused wires may be trimmed and finished as
necessary to prevent accidental contact with other wires or wire shields, or with a
ground connection.
Failure to observe these safety procedures could result in personal injury or
damage to the motor and equipment.
