General Installation Information
Fuses and Circuit Breakers
Frame 9 - 14 drives can be installed with either input fuses or an input
circuit breaker. National and local industrial safety regulations and/or
electrical codes may determine additional requirements for these
installations. Refer to
for recommended fuses/circuit breakers.
Power Wiring
Cable Types Acceptable for 200-690 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 (0.4mm/0.015 in.). Use Copper wire only. Wire
gauge requirements and recommendations are based on 75
°
C. Do not
reduce wire gauge when using higher temperature wire.
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.
!
ATTENTION: Frame 9 - 14 PowerFlex drives do not provide
branch short circuit protection. Specifications for recommended
fuses to provide protection against short circuits are provided in
!
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.
