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  
AC = 396 v  
NOTES:  
1. Minimum circuit amps (MCA) and MOCP values are calcu-  
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.

% Voltage Imbalance  
= 100 x  
= 1.5%  
397  
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.
