Fuses And Circuit Breakers - Allen-Bradley PowerFlex 70 User Manual

RFI Filter Grounding
Using an optional external 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

The PowerFlex 70 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
breakers.
ATTENTION: The PowerFlex 70 does not provide branch short
circuit protection. Specifications for the recommended fuse or circuit
