Power Wiring Connections

WARNING
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
NOTICE
Risk of damage to VFD, or malfunction can occur.
• Power source line to line, and line to ground voltages must be measured before connect-
ing 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 interfer-
ence 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 I I n n p p u u t t P P h h a a s s e e L L o o s s s s ( ( F F 3 3 1 1 ) ) .
• 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.
