3-WIRE CONNECTION INSTRUCTIONS
For existing installations ONLY, refer to Figure 9.
1 Follow the power supply kit manufacturerʼs Installation
Instructions supplied with the strain relief clamp and install.
See Figure 7.
2 Insert the end connectors for line 1, line 2 and neutral and
tighten securely to the terminal block. See Figure 7.
IMPORTANT
DO NOT LOOSEN the factory installed nut
connections which secure the range wiring to the terminal
block. Electrical failure or loss of electrical connection may
occur if these 3 nuts are loosened or removed.
3 Make sure all connections are tightened securely and replace
the rear access cover. See Figure 7.
GROUNDING INSTRUCTIONS- ONLY 3-WIRE CONNECTIONS:
A ground strap is installed on this range which connects the center
terminal of the neutral terminal block to the range chassis. The
ground strap is connected to the range by the center, lowest screw.
See Figure 9. The ground strap must not be removed unless National,
State or Local Codes do not permit use of a ground strap.
Note: If the ground strap is removed for any reason, a separate
ground wire must be connected to the separate ground screw
attached to the range chassis and to an adequate ground source.

INSTALLATION MANUAL
Before wiring the range, review the suggested power source location
drawings in Figure 2. If connecting to a 4-wire electrical system:
1 Follow the manufacturerʼs Installation Instructions supplied
with the strain relief clamp and install.
2 Strip insulation away from the ends of the permanent wiring
for line 1, line 2 and neutral; also strip ground wire on 4-wire
connections. Tighten all 3 or 4-wire leads to the terminal block.
Follow wire locations shown in Figure 10.
IMPORTANT
DO NOT LOOSEN the factory installed nut
connections which secure the range wiring to the terminal
block. Electrical failure or loss of electrical connection may
occur if these 3 nuts are loosened or removed.
Note: For 3-wire permanent connection skip steps 3 and 4 and
continue with step 5.
3 Disconnect the ground strap. Remove the factory installed
ground screw and plate to release the factory installed copper
ground strap from frame of the range. Cut and discard the
copper strap from the terminal block. KEEP the ground screw,
ground plate and go to step 4.
4 Connect the green ground wire lead to the frame of the range
using the ground screw and plate as shown in Figure 11. Be sure
to install using the same hole in the frame where the ground
screw was originally installed.
5 Make sure all connections are tightened securely and replace
the rear access cover. See Figure 7.
Note: Non-terminated field wire compression connections must
be set at approximately 90 in./lbs.
