PowerFlex 700 Adjustable Frequency AC Drive Quick Start 9
A variety of cable types are acceptable for drive installations. For many
installations, unshielded cable is adequate, provided it can be separated
from sensitive circuits. As an approximate guide, allow a spacing of 0.3
meters (1 foot) for every 10 meters (32.8 feet) of length. In all cases,
long parallel runs must be avoided. Do not use cable with an insulation
thickness less than or equal to 15 mils (0.4mm/0.015 in.). See
Table D.
Unshielded
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/Armored Cable
Shielded cable is recommended if sensitive circuits or devices are
connected or mounted to the machinery driven by the motor. See
Table
D. For further information on acceptable and unacceptable cable types,
refer to “Power Wiring” in the PowerFlex 700 User Manual.
