Wiring Requirements for the Drive 4-1
CHAPTER 4
Wiring Requirements for the Drive
Wire size should be determined based on the size of conduit openings, and applicable
local, national, and international codes, such as NEC/CEC. Evaluate wire sizes,
branch circuit protection, and E-stop wiring before continuing with the drive
installation.
4.1 Power Wiring
Input power wiring should be sized according to applicable codes to handle the drive’s
continuous rated input current. Output wiring should be sized according to applicable
codes to handle the drive’s continuous rated output current.
Cable Types Acceptable for 200-600 Volt Installations
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 (0.4 mm/0.015 in). Use
copper wire only. Wire gauge requirements and recommendations are based on 75
degree C. Do not reduce wire gauge when using higher temperature wire. See table
4.1.
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.
!
ATTENTION: The user is responsible for conforming with all applicable
local, national, and international codes. Failure to observe this precaution
could result in damage to, or destruction of, the equipment.
!
ATTENTION: National codes and standards (NEC, VDE, BSI, etc.) and
local codes outline provisions for safely installing electrical equipment.
Installation must comply with specifications regarding wire types,
conductor sizes, branch circuit protection and disconnect devices. Failure
to do so may result in personal injury and/or equipment damage.
