Power Wiring
Since most start-up difficulties are the result of incorrect wiring, take every
precaution to assure the wiring is correct. Read and understand all items in
this section before beginning installation.
Cable Types Acceptable for 400-690 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
!
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 Table 1.A
