CAUTION
Run input power, motor wiring and control wiring in three
separate metallic conduits or raceways for high frequency
noise isolation. Failure to isolate power, motor and control
wiring could result in less than optimum drive and
associated equipment performance.
•
Connect 3-phase AC input power wire to
terminals L1, L2, and L3. See the connection
drawing inside the cover of the unit.
•
Depending on the configuration of the
equipment, input power may be connected to a
circuit breaker or disconnect switch.
•
Torque terminals in accordance with the
information provided inTable 3.11 and Table 3.12
on the label inside the panel cover.
•
Use with Isolated Input Source. Many utility
power systems are referenced to earth ground.
Although not as common, the input power may
be an isolated source. All drives may be used
with an isolated input source as well as with
ground reference power lines.

WARNING
ELECTROCUTION AND FIRE HAZARDS WITH
IMPROPERLY INSTALLED AND GROUNDED FIELD
WIRING!
Improperly installed and grounded field wiring poses FIRE
& ELECTROCUTION hazards. To avoid these hazards, you
MUST follow requirements for field wiring installation and
grounding as described in the National Electrical Codes
(NEC) and your local/state electrical codes. All field wiring
MUST be performed by qualified personnel. Failure to
follow these requirements could result in death or serious
injury.

INDUCED VOLTAGE!
Run output motor cables from multiple 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.
NOTE!
Run input power, motor wiring and control wiring in three
separate metallic conduits or raceways for high frequency
noise isolation. Failure to isolate power, motor and control
wiring could result in less than optimum drive and
associated equipment performance.

WARNING
•
Connect the 3-phase motor wiring to bypass
terminals T1 (U), T2 (V), and T3 (W). See the
connection drawing inside the cover of the unit.
•
Depending on the configuration of the
equipment, motor wiring may be connected to
overload or terminal block.
•
Torque terminals in accordance with the
information provided on the connection diagram
inside the cover of the unit.
•
Motor wiring should never exceed the following
maximum distances: 300m (1000 ft) for
unshielded, 150m (500 ft) for shielded.
•
Motor wiring should always be as short as
practical.
