* Permissible limits of the voltage range at which the unit will operate
satisfactorily
NOTES:
1. Control circuit is 24-V on all units and requires external power
source. Copper wire must be used from service disconnect to unit.
2. All motors/compressors contain internal overload protection.
3. In compliance with NEC (USA Standard) requirements for multimo-
tot and combination load equipment (refer to NEC Articles 430 and
440), the over current protective device for the unit shall be fuse.
4. Motor RLA values are established in accordance with UL (Under-
writers' Laboratories) Standard 465 (USA Standard).
5. 38QRF018-030 units are only available in single-phase voltage.
6. Unbalanced 3-Phase Supply Voltage
Never operate a motor where a phase imbalance in supply voltage is
greater than 2%. Use the following formula to determine the percent-
age of voltage imbalance:
= 100 X max voltaqe deviation from averaqe voltaqe
average
EXAMPLE: Supply voltage is 460-3-60
A 8 C AB = 452v
M_OTO_j_R BC = 464v
AC = 455v
Average Voltage = 452 + 464 + 455
3
= 1371
3
= 457
Determine maximum deviation from average voltage:
(AB) 457-452 = 5v
(BC) 464-457 = 7v
(AC) 457-455 = 2v
Maximum deviation is 7v.
Determine percentage of voltage imbalance
7
% of voltage imbalance = 100 x 5-7-
= 1.53%
This amount of phase imbalance is satisfactory as it is below the maximum
allowable of 2%.
IMPORTANT: Contact your local electric utility company immediately if the
supply voltage phase imbalance is more than 2%.
