Motors are designed for satisfactory operation within 10% of
normal voltage shown. Voltages should not exceed the limits
shown in the Voltage Limits column.
AB = 393 v
BC = 403 v

lated in accordance with The NEC. Article 440.

3. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply
voltage is greater than 2%. Use the formula in the example
(see column to the right) to determine the percentage of volt-
age imbalance.
Determine maximum deviation from average voltage.
(AB) 397 – 393 = 4 v
(BC) 403 – 397 = 6 v
(AC) 397 – 396 = 1 v
4. Installation with Accessory Electric Heaters
Size the Field Power Wiring between the heater TB1 and the
40RU indoor fan motor per NEC Article 430---28 (1) or (2)
(depends on length of conduit between heater enclosure and
40RU power entry location). Install wires in field---installed
conduit.
Maximum deviation is 4 v.
Determine percent of voltage imbalance.

This amount of phase imbalance is satisfactory as it is below the
maximum allowable 2%.
IMPORTANT: If the supply voltage phase imbalance is more than
2%, contact your local electric utility company immediately.
