IF YOUR POWER SUPPLY CORD
OR DIRECT WIRING HAS PLAIN
WIRE ENDS, SEE FIGURE 15 AND
FOLLOW THESE STEPS:
1. Strip outer covering back 3 inches
from the end exposing the 3 wires.
2. Strip the insulation back 1 inch from
the end of each wire. Form the bare
wire into a U-shaped hook.
3. Loosen, do not remove, the center,
silver-colored screw of the terminal
block.
4. Slide the end of the neutral (white
or center) wire under the screw head
with the open side of the hook on
the right. Squeeze the wire together
to form a loop.
5. Tighten the screw firmly.
6. Connect the remaining 2 wires to the
outer screws the same way. Tighten
the screws firmly.

d. Connect the neutral wire of the
flexible armored or nonmetallic
sheathed copper power supply
cable to the center silver-colored
terminal screw of the terminal
block and connect the other wires
to the outer terminals. See Figure
12. For connecting plain-end
field wire, see Figure 15.
e. Replace the terminal block cover.

2. DO NOT permit connection of the
frame grounding conductor to the
neutral wire of the power supply
cord:
a. Remove terminal block cover.
b. Install U.L. approved strain relief
(Figure 11) in one inch hole on
dryer back below terminal block
opening.
c. Install copper power supply
cable.
d. Remove the ground wire (green)
from the green ground screw and
fasten under center silver-
colored terminal block screw.
e. Connect the neutral wire of the
power supply cable to the center
silver-colored terminal of the
terminal block and connect the
other wires to the outer
terminals. See Figure 13. For
connecting plain-end wire see
Figure 15.
Connect separate copper ground
wire from external ground connector
to approved ground.

f. Connect a separate copper
ground wire (No. 10 minimum)
to a grounded cold water pipe*
by means of a clamp and then to
the frame of the appliance at the
green ground screw. Use Part
No. 685463 ground wire and
clamp assembly. Do not ground
to a gas supply pipe. Do not
connect the power supply cord
to electric power supply until
appliance is permanently
grounded.
g. Replace the terminal block
cover.
*Grounded cold water pipe must have
metal continuity to electrical ground
and not be interrupted by plastic, rubber
or other electrical insulating connectors
(such as hoses, fittings, washers or
gaskets, including water meter or
pump). Any electrical insulating
connector should be jumped as shown
in Figure 9 with a length of No. 4 wire
securely clamped to bare metal at both
ends.
If connecting to a four-
wire electrical system
(mobile home):
1. Remove the terminal block cover.
2. Install U.L. approved strain relief
(Figure 11) in one inch hole on dryer
back below terminal block opening.
3. Install copper 4-wire power supply
cord.
4. Remove the ground wire (green)
from the green ground screw and
fasten under center silver-colored
terminal block screw.
5. Connect the ground wire (green) of
the copper 4-wire power supply cord
to the green ground screw.
6. Connect the neutral wire (white) of
the power supply cord to the center
silver-colored terminal screw of the
terminal block and connect the other
wires to the outer terminals. See
Figure 14. For connecting plain-end
field wire, see Figure 15.
7. Replace the terminal block cover.
