DANGER: INDUCED VOLTAGE! Run out-
put motor cables from multiple adjustable
frequency drives separately. Induced voltage
from output motor cables run together can
charge equipment capacitors even with the
equipment turned off and locked out. Failure
to run output motor cables separately could
result in death or serious injury.
• For maximum wire sizes, see “17.1 Power-depen-
dent Specifications” on page 75.
• Comply with local and national electrical codes for
cable sizes.
• Motor wiring knockouts or access panels are pro-
vided at the base of IP21 and higher (NEMA1/12)
units
• Do not install power factor correction capacitors
between the adjustable frequency drive and the
motor
• Do not wire a starting or pole-changing device
between the adjustable frequency drive and the
motor.
• Connect the 3-phase motor wiring to terminals 96
(U), 97 (V), and 98 (W).
