PERMANENT CONNECTION/HARD WIRING) --
Units may be hard wired to the power supply. The installer
must provide approved flexible aluminum conduit, 3/4"
(19mm) trade size, maximum 6ft (1.8m)long. Locate the
terminal block on the rear of the unit and remove cover
(refer to Figure 11). The conduit must be installed to the
terminal block using an approved conduit connector. The
free end of the conduit must be connected to a terminal
block provided in the electrical supply zone, as shown in
Figure 3a on page 7.
Mount a strain relief (not provided) into the 1" (25.4mm)
diameter hole located below the terminal block (see
Figure 12). Wiring for the unit is to be brought into the
terminal block through the conduit and through the strain
relief. The ends of the wiring must have 1/4" (6mm) faston
closed-loop lugs attached, preferably soldered in place.
Make the connections to the terminal block provided.
If aluminum supply wiring exists in the installation, splice
the aluminum house wiring with appropriate-thickness
gauge copper wire for adapting to the range, using special
connectors designed and certified for joining copper and
aluminum wire. Follow the connector manufacturer's
recommended installation procedure.
, WARNING:
Improper connection of aluminum house wiring can
result in a fire or shock hazard. Use only connectors
designed and certified for connecting to aluminum wire.
Installer -- show the owner the location of the circuit
