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 opend 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 damage to the drive.
• Ensure that the system is properly grounded all the way to the service entrance panel. Im-
proper grounding may result in loss of voltage surge protection and interference filtering.
• Use only copper wiring rated for 600 V with 75 °C insulation.
Before connecting power to drive, test incoming supply voltages to meet nameplate ratings as follows:
• 2 2 3 3 0 0 V V A A C C M M o o d d e e l l s s : : Each supply voltage line to line combination must measure between 190-253
VAC (208-230 VAC ±10%). Each line to ground voltage must be less than or equal to 253 VAC.
• 4 4 6 6 0 0 V V A A C C M M o o d d e e l l s s : : Each supply voltage line to line combination must measure between 414-506
VAC (460 VAC ±10%). Each line to ground voltage must be less than or equal to 506 VAC.
IMPORTANT: If any line to line voltage measures outside these ratings, the drive cannot be used on the
incoming power supply without an additional suitably sized transformer to bring the voltages within
these limits.
Jumper Locations:
1. J10 Jumper (two jumpers here).
2. J11 Jumper (two jumpers here).
IMPORTANT: Open Delta Power Supply – 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. If this is confirmed, the drive must be de-rated by 50% to prevent fault tripping on 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 ) ) and to prevent drive damage.
IMPORTANT: Corner-Grounded Delta Power Supply – 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 Delta power supply with corner grounding. If this is confirmed, re-
move Power Board EMC jumpers from J10 and J11 (four total). Ensure that supply earth grounding is provided per the NEC.
