Conduit Locations and Sizing
Use appropriate strain relief or conduit connectors.
Tighten seal nut to 25-30 in-lbs (2.8-3.4 Nm) and locking
nut to 15-20 in-lbs (1.7-2.2 Nm)
1.
Incoming power supply—Two available knockouts =
1.13 in. (28.7 mm), or 1.38 in. (35 mm).
2. Power output to motor—Hole = 1.69 in (43 mm),
knockout = 1.98in. (50.3 mm).
3. Control wiring (transducer/sensor) input—Hole =
0.5 in. (12.7 mm), plus two available knockouts = 0.5
in. (12.7 mm).
4. Optional cabling for auxiliary controls—Two avail

able knockouts = 0.91 in. (23 mm).
High Voltage Wiring Connections
Incoming Power Supply
Before connecting power to drive, test incoming voltages as follows:
•
460V Models:
The line to line and line to ground voltage must be 414-506V (460V +/-10%). The line to
ground voltage must be less than or equal to 506 V.
•
230V Models:
The line to line and line to ground voltage must be 207-253V (230V +/-10%). The line to
ground voltage must be less than or equal to 253 V.
If line to line voltage exceeds these ratings, the drive cannot be used on the incoming power supply. An
additional suitably sized transformer will be required to bring the voltages within limits.
If line to ground voltage exceeds these ratings, remove both pins of EMC jumper J10.

Contact with hazardous voltage could result in death or serious injury.
•
Disconnect and lock out all power before installing or servicing equipment.
•
Connect the motor, the drive, metal plumbing, and all other metal near the motor or cable to the
power supply ground terminal using wire no smaller than motor cable wires.
Risk of damage to drive
,
or malfunction can occur.
•
Power source line to line, and line to ground voltages must be measured before connecting the
drive. If line to ground voltage exceeds specification, both pins of EMC jumper J10 must be removed
to prevent damage to the drive. Refer to
“Incoming Power Supply” on page 4
.
•
Ensure that the system is properly grounded all the way to the service entrance panel. Improper
grounding may result in loss of voltage surge protection and interference filtering.
