Installation/Wiring 1-5
The PowerFlex 700 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 Appendix
A for recommended fuses/circuit
breakers.
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 (0.4mm/0.015 in.). Use Copper
wire only. Wire gauge requirements and recommendations are based on
75 degrees C. Do not reduce wire gauge when using higher temperature
wire.
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.
Fuses and Circuit Breakers
!
ATTENTION: The PowerFlex 700 does not provide branch short
circuit protection. Specifications for the recommended fuse or circuit
breaker to provide protection against short circuits are provided in
Appendix
A.
Power Wiring
!
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.
