If codes permit and a separate ground wire
is used, it is recommended that a qualified
electrician determine that the ground path
is adequate.
Do not ground to a gas pipe.
Check with a qualified electrician if you are
not sure whether the cooktop is properly
grounded.
Do not have a fuse in the neutral or ground
circuit.
1. A three-wire or four-wire, single phase,
240-volt, 60-Hz, AC-only electrical supply
is re uired on a separate, 40-ampere cir-
cuit, fused on both sides of the line. A time-
delay fuse or circuit breaker is recom-
mended. The fuse size must not exceed
the circuit rating of the appliance specified
on the model/serial rating plate located on
the bottom of the cooktop.
THE COOKTOP MUST BE CONNECTED
WITH COPPER WIRE ONLY.

ELECTRICAL REQUIREME TS
2. Wire sizes and connections must conform
to the re uirements of the National Electri-
cal Code ANSI/NFPA 70 — latest edi-
tion**, or CSA Standards C22.1-94, Cana-
dian Electrical Code, Part 1 and C22.2 No.
0-M91 — latest edition*** and all local
codes and ordinances.
3. The cooktop should be connected directly
to the fused disconnect or circuit breaker
box through flexible, armored or non-me-
tallic sheathed, copper cable. The flexible,
armored cable extending from the fuse
box or circuit breaker box should be con-
nected directly to the junction box.
4. Locate the junction box to allow as much
slack as possible between the junction
box and the cooktop so that the cooktop
can be moved if servicing is ever neces-
sary. Do ot cut the conduit.
5. A U.L. - or C.S.A.-listed conduit connector
must be provided at each end of the power
supply cable (at the cooktop and at the
junction box).

2. Connect the flexible, armored cable from
the cooktop to the junction box using a
U.L.- or C.S.A.-listed conduit connector,
and tighten the screws on the conduit
connector.
3. Connect the two black wires together;
then connect the two red wires together
using a twist-on connector.
4. Connect the green or bare ground wire
from the appliance cable to the grounded
wire in the junction box, or other grounded
connector using a twist-on connector.
5. Install a twist-on connector on the end of
the white wire.
1. Disconnect the power supply.
2. Connect the flexible, armored cable from
the cooktop to the junction box using a
U.L.- or C.S.A. -listed conduit connector
and tighten the screws on the conduit
connector.
3. Connect the green (or bare) appliance
cable wire with the neutral (white) wire in
the junction box using a twist-on connec-
tor.
Grounded eutral
Ungrounded eutral
Where local codes permit connecting the
frame-ground conductor to the neutral
(white) junction box wire (not used for Ca-
nadian installations):
This cooktop must be connected to a
grounded, metallic permanent wiring sys-
tem or a ground connector should be
connected to the ground terminal or wire
lead on the cooktop.
This cooktop is manufactured with a frame
connected, green or bare ground wire. Con-
nect the cooktop cable to the junction box
through the U.L. - or C.S.A.-listed conduit con-
nector. Complete electrical connection accord-
ing to local codes and ordinances.
WARNING
Electrical Shock Hazard
Turn power supply off before connect-
ing wires.
Use 8-gauge solid copper wire.
