Fig. 2 — Line Power Connections
Install a Branch Circuit Fused Disconnect
of adequate size
to handle unit starting current Locate disconnect within
sight of and readily accessible to the unit, per section
440-14 of National Electrical Code (NEC).
Bring Line Power Leads Into Unit
— Extend leads from
fused disconnect thru hole provided in base pan (Fig. 1)
and into unit junction box.
CONNECT GROUND LEAD TO GROUND LUG OR
SCREW IN JUNCTION BOX for safety. Connect power
wiring. See Fig. 2. Splice line power leads to brown and
orange pigtails on 1-phase units or brown, orange and black
pigtails on 3-phase units. Use wire nuts supplied with unit.
Tape each connection. When aluminum field wire is used,
lubricate splices with splice compound (also supplied)
before using wire nuts.
Control Power
(24 v) wiring is brought thru hole provided
in unit base pan (Fig. 1) and into low-voltage section of
unit junction box. Splice control leads to yellow pigtails on
control relay. See Fig. 3. For aluminum wire splices use
factory supplied and lubricated wire nuts. Furnace or fan
coil transformer must be used as 24-v supply for system as
shown in Fig. 3. All 38SE units are equipped with
transformer used to power contactor thru unit control
circuit only, and must not be used to power thermostat
circuit.
