& WARNING
To prevent electrical shock, the grounding prong on
the range cord should not be cut or removed under
any circumstances. It must be plugged into a
matching grounding type receptacle and connected
to a correctly polarized 240-Volt circuit. If there is
any doubt as to whether the wall receptacle is
properly grounded, have it checked by a qualified
electrician.
Four-wire Range Cord Connection
(Recommended Method)
1. Disconnect electrical power at breaker box. Remove
the terminal block cover to expose the terminal block.
2. Remove the top nut (has an attached locking washer)
from each post.
Note: DO NOT remove the second nut/washer on each
post; these must stay in place to anchor the internal
wiring attached to the terminal block.
3. Remove screw from the bottom end of the ground
strap.
4. Remove the green grounding screw from the lower end
of the grounding strap. Remove the upper end of the
grounding strap from the center post of the junction
9000989333 Rev D
bar. Rotate the grounding strip (A) so that the wide end
is up and align the hole with the grounding hole below
the terminal block. Use the green grounding screw (B)
to attach the green wire (G) on top of grounding strap.
Tighten the grounding screw firmly, but do not
overtighten.
5. Attach the red wire to the left junction block terminal
using one of the nut/washers removed in step 2.
6. Attach the white wire to the center junction block
terminal using one of the nut/washer parts.
7. Attach the black wire to the right junction block terminal
using one of the nut/washer parts.
8. Tighten all connections securely and replace terminal
block cover.
9. Properly secure strain relief (see previous section).
Note: DO NOT plug in the range at this time.
Three-wire Range Cord Connection (Alternate Method)
The four-wire connection (above) is preferred, but where
local codes and ordinances permit grounding through the
neutral and where conversion to four-wire is impractical,
the unit may be connected to the power supply via a three-
wire connection.
