NOTES:

1.In compliance with NEC requirements for multimotor and combi- nation load equipment (refer to NEC Articles 430 and 440), the overcurrent protective device for the unit shall be fuse or HACR breaker.

2.Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt- age is greater than 2%. Use the following formula to determine the percent of voltage imbalance.

= 100 x

max voltage deviation from average voltage

average voltage

 

Example: Supply voltage is 460-3-60.

AB = 452 v BC = 464 v AC = 455 v

Average Voltage = 452 + 464 + 455 3

1371

=

3

= 457

Determine maximum deviation from average voltage.

(AB) 457 – 452 = 5 v (BC) 464 – 457 = 7 v (AC) 457 – 455 = 2 v

Maximum deviation is 7 v.

Determine percent of voltage imbalance.

7

% Voltage Imbalance = 100 x 457

= 1.53%

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.

3.The 575-v units are CSA only.

4.the 380 v, 60 Hz units and all 50 Hz units are not UL or CSA listed.
