Insulate Motor Terminals and Lead Wire Ends
Insulate compressor motor terminals, lead wire ends, and electrical wires to prevent moisture
condensation and electrical arcing. For low-voltage units (up to 600 v), obtain insulation
material from machine shipping package consisting of 3 rolls of insulation putty and one roll of
vinyl tape.
1. Insulate each terminal by wrapping with one layer of insulation putty.
2. Overwrap putty with 4 layers of vinyl tape.
High Voltage Units
High-voltage units require special terminal preparation. Follow local electrical codes for high-
voltage installation. The vinyl tape is not acceptable, a high voltage terminal methods must be
used.
