ELECTRICAL SHOCK AND FIRE HAZARD
Failure to follow this warning could result in serious inju U,
death, or property damage.
The cabinet MUST have an uninterrupted or unbroken ground
according to NEC ANSI NFPA 70-2002 and Canadian Elec=
tdcal (7ode CSA (22.1 or local codes to minimize personal
injury if an electrical _Sult should occur. This may consist of
electrical wire, conduit approved for electrical ground or a
listed, grounded power cord (where permitted by local code)
when installed in accordance with existing electrical codes.
Refer to the power cord manufacturer's ratings for proper
wire gauge. Do not use gas piping as an electrical ground.

Verif}_" tl_at the voltage, frequency, and phase correspond to that
specified on unit rating plate. Also, check to be sure that service
provided by udlity is sufficient to handle toad imposed by this
equipment. Refer to rating plate or Table 7 _br equipment electrical
specifications.
[.S. installations: Make all electrical connections in accordance
with National Electrical (?ode (NEC) ANSI NFPA 70-2002 and
any local codes or ordinances that might apply.
Canadian installations: Make all electrical connections in accor-
dance with Canadian Electrical (?ode CSA C22.1 or authorities
having jurisdiction.
---> FIRE HAZARD
Failure to %llow this warning could result in serious inju V,
death, or property damage.
Do not connect aluminum wire between disconnect switch
and Nmace. Use only copper wire.
Use a separate, Nsed branch electrical circuit with a properly sized
Nse or circuit breaker for this Nmace. See Table 7 tbr wire size
and Nse specifications. A readily accessible means of electrical
disconnect must be located within sight of the furnace.
NOTE: Proper polarity must be maintained for 115-v wiring. If
polarity is incorrect, contIol LED status indicator light will flash
rapidly and Nmace will NOT operate.
J=BOX RELOCATION
NOTE: If factory location of J-Box is acceptable, go to next
section (Electrical Connection to J=Box).
NOTE: On 14" wide casing models, the J=Box shall not be
relocated to other side of £umace casing when tiae vent pipe is
routed within the casing.
1. Remove and save two screws holding J-box. (See Fig. 22.)
---> NOTI=: The J=Box cover need not be removed L'rom the J=Box in
order to move the J=Box. Do NOT remove green ground screw
inside J=Box. The ground screw is not threaded into the casing
flange and can be lifted out of the clearance hole in casing while
swinging the t?ont edge of the J-Box outboard of the casing.
