About Standard Power Cables
Standard motor power cables, with or without brake connections, have a 58 mm (2.3 in.) circular
DIN connector at the motor end, and flying leads at the drive end. These cables can be bent or
reformed during installation or maintenance, but should not be used in a continuous flex
operation.

Before You Begin
Remove all packing material from within and around the item. After unpacking, verify the
catalog number against the purchase order, and visually inspect the cable and each connector for
damage. If necessary, notify the carrier of any shipping damage immediately.
Cables are stored and shipped in a coil, and will retain this shape unless you allow the cable to
straighten itself. To straighten a cable, hang a short cable from its mid-point or lay a long cable on
the floor in a straight line. Any coiling that persists in the cable should relax within the next
twenty-four hours. Doing this results in a cable that is easier to install.
Observe the following precautions when installing the cables in a servo system. Failure to observe
these safety notices could result in personal injury or damage to the motor and equipment.
ATTENTION: Arcing or unexpected motion can occur if the power, brake, or
feedback cables are connected or disconnected while power is applied to the
drive.
Always remove power to the servo drive before connecting or disconnecting
cables at the drive or at the motor.
ATTENTION: To avoid the hazard of electrical shock, make sure shielded power
cables are grounded at a minimum of one point. To prevent the build-up of
electrical energy, factory supplied power cables use one of these grounding
techniques:
• The overall shield is bonded to the connector housing.
• A section of the overall shield is exposed for connection to ground.
• The overall shield is connected to a ground wire.
If the exposed cable braid or a ground wire is present, connect it to the power
cable clamp, housing, or another suitable chassis ground on the drive.
ATTENTION: The maximum length of cabling between the drive and the motor
must not exceed 90 m (295.5 ft), and a maximum of two (2) extension cables
may be connected between a drive and a motor. Refer to Kinetix Motion Control
Selection Guide, publication GMC-SG001
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 a authoritative directive, such as
Engineering Section 310.15(C) of the NEC Handbook.
