Figure 15, Figure 16, and Figure 17 illustrate 3 methods for assembling multiple lead wires
within the compressor terminal box. For the purposes of illustration, the terminal insulation has
been omitted.
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.
Important: Do not insulate terminals until wiring arrangement has been checked and
approved by Carrier start-up personnel. Also, make sure correct phasing is followed
for proper motor rotation.
