ELECTRICAL DATA

ELECTRICAL SHOCK HAZARD

DO NOT alter cord or plug, and DO NOT use an

extension cord. Personal injury or damage to the

unit may result.

Be sure that your outlet matches the appropriate

blade configuration of the supplied plug and that it is

within reach of the service cord. A hardwire kit is

available as an accessory to change cord-connected

units to hardwired units. (See Accessories table on

page 15.)

IMPORTANT: All standard cord-cormected 265-v

units will require a field-installed electrical sub-

base accessory.

ALL UNITS

m 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 single branch cir-

curs only.

NOTE: Use copper conductors only.

I GROUNDING -- For safety and protection, the

unit is grounded through the service cord plug or

through separate ground wire provided on hardwired

units. Be sure that the branch circuit or general pur-

pose 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

(shown in Figure 1).

l CORD-CONNECTED UNITS -- The 250-v field-

supplied outlet must match the plug for the standard

208/230-v units and be within reach of the service

cord. The standard cord-connected 265-v units require

an accessory electrical subbase for operation. See

Accessories table, page 15, for subbase selection. Refer

to Table 2 for proper receptacle and fuse type.

• POWER CORD PROTECTION -- The power cord

for the 230/208-v unit provides both personal shock

protection and power cord F_re prevention. Unit power

automatically disconnects when unsafe conditions are

detected. Power to the unit can be restored by pressing

the RESET button on plug head.

Upon completion of unit installation for 230/208-v

models, an operational check should be performed

using the TEST/RESET buttons on the plug head. See

Figure 5.

NOTE: The 265-v models do not incorporate this

feature as they require use of the electrical subbase

accessory.
