General Installation Information 1-3
RFI Filter Grounding
Using an optional RFI filter may result in relatively high ground leakage
currents. Therefore, the filter must only be used in installations with
grounded AC supply systems and be permanently installed and solidly
grounded (bonded) to the building power distribution ground. Ensure that
the incoming supply neutral is solidly connected (bonded) to the same
building power distribution ground. Grounding must not rely on flexible
cables and should not include any form of plug or socket that would permit
inadvertent disconnection. Some local codes may require redundant ground
connections. The integrity of all connections should be periodically
checked. Refer to the instructions supplied with the filter.
Fuses and Circuit Breakers
High Power drives should be installed with input fuses. 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.
Power Wiring
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.

ATTENTION: PowerFlex High Power drives do not provide
branch short circuit protection. Specifications for recommended
fuses to provide protection against short circuits are provided in
Appendix A
.
!
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.
