WARNING
!
POwEr COnnECTIOn OPTIOns
Appropriate power cord accessory kit is determined by the voltage, and amperage of the branch circuit.
The unit does not come
with a power cord (or hard wire kit)
. An accessory power cord kit must be ordered to connect the unit to the outlet. If the unit is
to be hard wired, an accessory hard wire kit must be ordered.
IMPOrTanT : For 265V units, if a power cord is selected, it must plug into the 265V subbase accessory.
Be sure that your outlet matches the appropriate blade configuration of the plug and that it is within reach of the service cord.All
wiring, including installation of the receptacle, must be in accordance with the NEC and local codes, ordinances and regulations.
National codes require the use of an arc fault or leakage current detection device on all 208/230V power cords. Be sure to select
the correct cord for your installation.

wire size
Use recommended wire size given in Table 1 and install a single branch circuit.All wiring must comply with local and national
codes. All units are designed to operate off ONE single branch circuit only.

Grounding
For safety and protection, the unit is grounded through the service cord plug or through separate ground wire provided on
hard wired units. Be sure that the branch circuit or general purpose outlet is grounded.
VOlTaGE suPPlY
Check voltage supply at outlet. For satisfactory results, the voltage range must always be within the ranges found on the
data information plate.
Cord-connected units
The 250V field supplied outlet must match the plug for the standard 208/230V units and be within reach of the service
cord. The standard cord-connected 265V units require an accessory electrical subbase for operation. Refer to Table 2 for
proper receptacle and fuse type.
Power Cord Protection
The power cord for 230/208v units provide power cord fire protection.Unit power automatically disconnects when unsafe condi-
tions are detected. Power to the unit can be restored by pressing the reset button on plug head. Upon completion of unit instal-
lation for 230/208V models, an operational check should be performed using the TEST/RESET buttons on the plug head.
nOTE : The 265V models do not incorporate this feature as they require use of the electrical subbase accessory.
