WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury. Disconnect all electric
power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the
power can not be inadvertently energized. Verify that
no power is present with a voltmeter.
Note: All wiring must be provided in accordance with
National Electrical Code and local code
requirements. Use copper conductors only. Wiring
terminations may become loose during transit of

Use
the equipment; verify all wiring terminations are
secure.
A manual fused disconnect switch must be provided per
the National Electrical Code and local codes for servicing
the equipment. Do not mount a shipped-loose, non-fused
service switch or customer supplied disconnect switch to
the surface of the unit. If a factory installed, non-fused
service switch option was purchased, the main power and
ground connection is located at the switch; otherwise, the
main power connection is located as stated below.
The unit is provided with pilot hole(s) in the main power
and control panel for routing field-wiring. These pilot
holes are located near the electric box and a label stating
"MAIN POWER INPUT" is in close proximity. Terminate the
main power wires at the line side of the main power
distribution block located within the electric box. A
separate equipment ground lug is provided inside the
electric box for terminating an earth ground wire.
Note: Prior to operation, an adequate unit-to-Earth
ground must be connected to the unit.
Single-Phase Units 208/230V
The supply voltage for units designed to operate at 208V
must be within -5% and +10% tolerance. If the measured
supply voltage is 230V, the unit can operate with a
tolerance of ±5% if the following change is performed: The
control transformers within the system must have the
primary wire connected to its respective 240V tap instead
of the 208V tap.
Single-Phase Units 277V
Single-phase units require that the hot leg of power be
connected to terminal L1 and the neutral wire to terminal
L2 of the main power distribution block.
Three-Phase Units
Three-phase units are designed to have the L1, L2 and L3
supply wires connected to corresponding L1, L2 and L3
line terminals of the main power distribution block. The
unit will operate correctly if the supply wires are connected
in this manner. A ground lug is provided in each unit near
the distribution block.
CAUTION
Compressor Damage!
Improper wire connections will result in reverse
rotation of the blower motors and compressor (if
applicable) and may eventually result in damage to the
compressor. To correct this problem, exchange any two
of the incoming main power wires at the main power
distribution block. Do not rewire the unit's individual
components.
