* P ermissible 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 co mpliance wi th NEC (USA Standard) requirements for multimo-
tor and combination load equipment (refer to NEC Articles 430 and
440), the over current protective device for the unit shall be f use.
4. Motor RLA valu es 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. Unbalance d 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 voltage deviation f rom average
voltage

EXAMPLE: S uppl y vol tage is 460 ---3 ---60
AB = 452v
BC = 464v
AC = 455v
Average V oltage = 452 + 464 + 455

Determine maximum deviation from average voltage:
(AB) 457---452 = 5v
(BC) 464---457 = 7v
(AC) 457---455 = 2v
Maximum deviation is 7v.

= 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
suppl y voltage ph ase imbalance is more than 2%.
