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 voltage imbalance.
max voltage deviation from average voltage
= 100 x
average voltage
EXAMPLE: Supply voltage is 460-3-60.
AB =452 v
BC =464 v
AC =455 v
452 + 464 + 455
Average Voltage =
3
1371
=
3
= 457
(AB) 457 - 452 =5 v
(BC) 464 - 457 =7 v
(AC) 457 - 455 =2 v
Maximum deviation is 7 v.
Determine percent 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.
