Shaded values are LRA drawn by first winding of
-> part-winding start units (not standard on 38AB054,064,
but may be field modified) See Note 1 Larger value is
total LRA.
FLA - Full Load Amps
ICF — Maximum Instantaneous Current Flow (sum of LRA of
last compressor to start and FLA of all other motors in
unit, and control circuit current)
LRA — Locked Rotor Amps
MWA — Minimum Wire Amps per NEC, Section 430-24 Values
based on maximum of 1% voltage drop in line.
*Units are suitable for use on electrical systems where voltage
supplied to the unit terminals is never below or above the listed
limits
tUnits 38AB084 (208 , 230-volt only) have two power connections
Maximum wire size is 350 MCM each
NOTES
1 Dual compressor units have a 4- to 12-second delay between
first- and second-compressor start-up Units are supplied with
either across-the-line or part-winding start, depending on unit
size and voltage Refer to Electrical Data table Where two LRA
values are shown, units are part-winding start, (all others are
across-the-line)
2 Units have factory-installed circuit breakers and/or pullout fuses
that meet NEC requirements for branch circuit over-current
protection and in-sight disconnect Consult local codes
3 Maximum Incremental Current Inrush during start-up is LRA
drawn by first winding of part-winding start unit (shaded area)
or across-thedine LRA of largest compressor when part-winding
start is not available
4 Fans no 1 and 4 have single-phase speed control motors on 208-
and 230-volt units
5 Units 38AB054 and 064 which have two contactors, can be
converted to part-winding start by addition of two time-delay
relays (Carrier part no HN67SK001 for 208- and 230-volt units,
or no HN67SK002 for 460- and 575-volt units) Two additional
contactors are also required with 460- and 575-volt units to be
wired same as other part-wind compressors
On 38AD024 thru 034 units, power terminal
block is in the control box. Remove the outer
panel and remove the no. 10 screw on the door.
Swing open door, remove screws on barrier panel
and remove barrier panel. On 38AB054,064 and
084 units, remove two screws holding hinged sheet
metal barrier and swing open barrier.
Condenser fans must rotate clockwise when
viewed from above. If necessary, correct direction
of fan rotation by interchanging any two power
input wires at disconnect switch.
Affix crankcase heater decal to unit disconnect
switch.
Control Circuit Wiring — Internal control voltage
on 38AD units is 115 volts. Internal control
voltage on 208- and 230-volt 38AB units is the
same as unit voltage. On 460- and 575-volt 38AB
units, it is 115 volts. All control circuit wiring must
comply with applicable local and national codes.
Remote control wiring must enter unit control box
thru control opening (G on Fig. 1) and connect to
terminal block inside the control box.
