Cable Recommendations - Power
Unshielded Cable
THHN, THWN or similar wire is acceptable for drive installation in dry environments provided adequate free air space
and/or conduit fill rates limits are provided. Do not use THHN or similarly coated wire in wet areas. Any wire chosen
must have a minimum insulation thickness of 15 Mils and should not have large variations in insulation concentricity.
Shielded Cable
Shielded cable contains all of the general benefits of multi-conductor cable with the added benefit of a copper braided
shield that can contain much of the noise generated by a typical AC Drive. Strong consideration for shielded cable should
be given in installations with sensitive equipment such as weigh scales, capacitive proximity switches and other devices
that may be affected by electrical noise in the distribution system. Applications with large numbers of drives in a similar
location, imposed EMC regulations or a high degree of communications/ networking are also good candidates for shielded
cable.
Shielded cable may also help reduce shaft voltage and induced bearing currents for some applications. In addition, the
increased impedance of shielded cable may help extend the distance that the motor can be located from the drive without
the addition of motor protective devices such as terminator networks. Refer to “Reflected Wave” in publication DRIVES-
IN001…, Wiring and Grounding Guidelines for Pulse Width Modulated (PWM) AC Drives.
Consideration should be given to all of the general specifications dictated by the environment of the installation, including
temperature, flexibility, moisture characteristics and chemical resistance. In addition, a braided shield should be included
and be specified by the cable manufacturer as having coverage of at least 75%. An additional foil shield can greatly
improve noise containment.

Note: The 115 VAC Digital Inputs can withstand 2 milliamps of
leakage current without turning on. If an output device has a leakage
current greater than 2 milliamps a burden resistor is required. A 68.1K
ohm resistor with a 0.5 watt rating should be used to keep the 115
VAC output below 2 milliamps.
