When any compressor bearing unit is connected to a weak power supply, starng current will generate a signicant “sag” in the
voltage which reduces the starng torque of the compressor motor and increases the start me. This will inuence the rest of
the electrical system in the building by lowering the voltage to the lights. This momentary low voltage causes “light dimming”.
The total electrical system should be evaluated with an electrician and HVAC technician. The evaluaon should include all
connecons, sizes of wires, and size of the distribuon panel between the unit and the ulity’s connecon. The transformer
connecon and sizing should be evaluated by the electric ulity provider.

Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and local codes, whichever is the most
stringent.
2. In determining the correct supply wire size and maximum length, reference NFPA 70, Section 310. If the calculation is
close to the maximum allowable ampacity of a particular wire size, use the next size up. This will ensure that no adverse
effects occur, such as light dimming and/or shortened compressor life.
3. All fuses class RK-5.
4. Min/Max Voltage: 208/230/60 = 187-252
5. CMCC (Compressor Maximum Output Current Limit): This value is the maximum output of the dirve (inverter) to the
compressor. Although not significant to the installation (continue to use MCA for wire/breaker sizing), this value is a required
listing for the unit electrical data.
