Put power supply cord through the strain relief. Be sure that
the wire insulation on the power supply cord is inside the
strain relief. The strain relief should have a tight fit with the
dryer cabinet and be in a horizontal position. Do not further
tighten strain relief screws at this point.
Remove the screws from a 3/4" (19 mm) UL listed strain relief
(UL marking on strain relief). Put the tabs of the two clamp
sections (C) into the hole below the terminal block opening
(B) so that one tab is pointing up (A) and the other is pointing
down (D), and hold in place. Tighten strain relief screws just
enough to hold the two clamp sections (C) together.
Remove center terminal block screw (B). Remove neutral
ground wire (E) from green external ground conductor screw (A).
Connect neutral ground wire (E) and neutral wire (white or
center) (C) of power supply cord under center terminal block
screw (B). Tighten screw.
