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 dis-
connected 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.

Ground Connections
