Power Wiring

Because most start-up difficulties are the result of incorrect wiring, take
every precaution to verify that the wiring is correct. Read and understand all
items in this section before beginning installation.

Cable Types Acceptable for 400-690 Volt Installations

!

ATTENTION: Most codes require that upstream branch circuit
protection be provided to protect input power wiring.

The PowerFlex 700L Frame 2 drive does not provide input power
short circuit protection. Specifications for the recommended fuse
or circuit breaker to provide Frame 2 drive input power protection
against short circuits are provided in

Table A.F

and

Table A.G

.

Frame 3A and 3B complete drives include an input power circuit
breaker. The value of the circuit breaker provided with the drive is
listed in
