A. Center silver-colored terminal block screw
B. Neutral grounding wire (white or green/
yellow)
C. ¾” (1.9 cm) UL-listed strain relief
D. Neutral wire (white or center wire)
E. External ground connector
F. Green or bare copper wire of power cord
1. Remove the external ground connector’s
screw, and connect the ground wire (green or
unwrapped) of the power cable to the screw.
CAUTION
• To connect the ground wire to the neutral
position without through contact A (cabinet
ground), contact a technician. This is not user
serviceable.
• Ring-type terminals are recommended. If
using strap terminals, make sure they are
tightened.
2. Loosen or remove the screws from the center
terminal block.
3. Connect the neutral wire (white or center wire)
and ground wire (white) to the center, silver-
colored terminal screw of the terminal block.
Tighten the screw.
4. Connect the other wires to the outer terminal
block screws. Tighten the screws.
5. Tighten the strain relief screws.
6. Insert the tab of the terminal block cover into
the rear panel of the dryer. Then, secure the
cover with a hold-down screw.
CAUTION
Connect the power cord and check L1/L2/N voltage. If the voltage is low, it may not heat properly.
WARNING
• All U.S. models are designed for a 3-wire system connection. The dryer frame is grounded to the
neutral conductor at the terminal block. A 4-wire system connection is required for new or remodeled
construction, mobile homes, or if local codes do not permit grounding through neutral. If you use the
4-wire system, you cannot ground the dryer frame to the neutral conductor at the terminal block.
