Power Wiring Connections
Contact with hazardous voltage could result in death or serious injury.
• Disconnect and lock out all power before installing or servicing equipment.
• Make sure that all DC bus capacitor voltage has dissipated for several minutes after VFD power is disconnected
before working on wiring.
• 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.
• All wiring must comply with the National Electrical Code and local codes.
Incoming Power Supply
Risk of damage to drive
• Power source line to line, and line to ground voltages must be measured before connecting the drive.
• If a Corner-Grounded Delta Power Supply is used, all EMC jumpers at J10 and J11 must be removed to prevent
drive damage.
• If an Open Delta Power Supply is used, the drive must be derated by 50% to prevent drive damage and fault
tripping.
• Ensure that the system is properly grounded all the way to the service entrance panel, per the NEC. Improper
grounding may result in loss of voltage surge protection and interference filtering.
Use only copper wiring rated for 600 V with 75 C insulation.

Power Board EMC Jumper Locations:
1. J10 Jumper (two jumpers here)
2. J11 Jumper (two jumpers here)
Before connecting power to drive, test incoming supply voltages to meet nameplate ratings as follows:
Model
230 VAC
460 VAC
• If any line to line voltage measures outside these ratings, do not use the drive on the incoming power
supply. Add a suitably-sized transformer to bring the voltages within these limits.
• If line to line voltage is imbalanced, or line to ground voltage is low on one phase, this may be an Open
Delta Power Supply. This could cause Input Phase Loss (F31).
• If one or more line to ground voltage measures 0 V or less than noted above, check system fuses. If
fuses are good, this may be a Corner-Grounded Delta Supply.
Ground Connections
Follow these grounding requirements to ensure safety and performance
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.
