Power Wiring Connections
Incoming Power Supply
Before connecting power to drive, test incoming voltages as follows:
•
230V Models:
The line to line and line to ground voltage must be 190-253V (208-230V ±10%). The line
to ground voltage must be less than or equal to 253 V.
•
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.
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.
IMPORTANT:
If line to ground voltage exceeds these ratings, remove Power Board EMC jumpers from J10
and J11 (four total). This is common in applications supplied by a Corner-Grounded Delta transformer. Refer
to the NOTICE above.
1.
Incoming Power terminal block.
2. Power Out to Motor terminal block. If the drive is equipped with a dV/dt
(EMI) filter, this terminal block is pre-wired to the dV/dt filter. The motor
is wired to the terminal block on the dV/dt filter.

4. J11 Jumper location (two jumpers here).
Ground Connections
1.
Make sure a service entrance ground rod is properly installed and connected.
2. An input power ground wire from the supply panel must be connected to the drive.
3. A dedicated output ground wire from the drive must be connected to the motor. Motor and ground
wires must be bundled together.
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.
•
Close any open conduit holes before finishing installation.
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” below.
•
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.
