Main Electrical Power
Lock and tag out unit main electric power and remove
power supply wiring from installed disconnect/terminal
block of unit. See for locations.
N No otte e:: Inspect wiring to ensure that all field-installed
wiring complies with NEC and applicable local
codes.
SEHF Units with 200V or 230V Electric
Heat
(Requires separate power supply to heater)
Lock and tag out unit main electric power and remove
power supply wiring for the electric heat from a
dedicated, field- supplied/installed disconnect to
terminal block, or to an optional unit-mounted
disconnect switch. See for locations.
Field-installed Control Wiring
N No otte e:: Inspect wiring to ensure that all field-installed
wiring complies with NEC and applicable local
codes.
Remove the field wiring connections for the variable air
volume controls as applicable.
N No otte e:: Label wiring to save time when reconnecting
wiring is necessary.
Remove ground wire from the unit.
N No otte e:: The electrical connection for 40, 60, 70 and 75 ton
is 32 inches further down the unit than older
(pre-2010) style units. On full perimeter curbs,
this also means the incoming electrical will be
outside the curb area. The electrician should be
informed of both points.
See for typical field wiring for 20-75 ton units. See
Figure 32, p. 52 for typical field power wiring for 90-130
ton units.
