*Per missible limits of the voltage ran ge at which the unit will oper ate
satisfactorily
NOTES:
1. Control circuit is24 ---V on all units and requires external power
source. Copper wire mustbe used from service disconnectto unit.
2. All motors/compressorscontain internal overloadprotection.
3. In compliance with NEC (USA Standard) requiremen tsf ormu ltimo-
tor and combination load e quipment (refer to NEC Article s 430 and
440),the over curren tprotective device for the unit shall be fuse.
4. Motor RLA values are establishedin accordance with UL (Under-
writers’Laboratories) Standard 465 (USA Standard).
5. 38QRF018---030 unitsar e only available in single---phasevoltage.
6. Unbalanced3---PhaseSupply Voltage
Neveroperate a motor where a phase imbalance in supply voltage i s
greaterthan 2%. Usethe following formula to determine the percent-
ageof voltage imbalance:
=100 X maxvoltage deviation from average vo ltage
average
EXAMPLE: Su p p l y vo l t a g e is 46 0 ---3 ---60
AB= 452v
BC= 464v
AC= 455v
Average Voltage = 452 + 464 + 455
3
=1371

=457
Determine maximum deviatio n from average volta ge:
(AB)457 ---452= 5v
(BC)464 ---457= 7v
(AC)457 ---455= 2v
Maximum deviation is 7v.
Determinepercentageofvoltageimbalance
%of voltag e imbalance = 100 x 7

= 1.53%
Thisamount of phase imbalance is satisfactory as it is below the maximum
allowableof 2%.
IMPORTANT: Contact your local electric utility com pany immediately if the
supplyvoltage phase imbalance is more than 2%.
