All Units — Voltage to compressor terminals during operation must be within voltage range indicated on unit nameplate. See Tables 10 and 11. On 3-phase units, voltages between phases must be balanced within 2% and the current within 10%. Use the formula shown in the legend for Tables 10 and 11, Note 4 (see page 23) to determine the percent of voltage imbalance. Operation on improper line voltage or (Note 2) excessive phase imbalance constitutes abuse and may cause damage to electrical components
