WIRING INSTRUCTIONS
1.
Unscrew cover to expose the switching element for wiring
or replacement. To aid in cover removal, a screwdriver or
bar may be used on the wrenching lugs. Use up to size #12
AWG solid or stranded wire to connect to the pressure type
connector terminals. Stripped wire ends or any spade and
ring connector that will fit the terminals may be used. Spades
may be up to 7,9 mm [0.312 in] wide, rings up to 7,9 mm
[0.312 in] diameter. With spade or ring type connections
preinsulated connectors or heat-shrinkable tubing should
be used to provide insulation between terminals. Conduit
size, electrical ratings and circuit diagram are shown on the
nameplate. Wire the double pole units by connecting lead
wires to the terminals nearest the conduit opening first. An
internal grounding screw is located on the right side; an
external grounding screw is located on the upper left side.
Torque all terminal screws and grounding screws to 1 Nm to
1,8 Nm [9 in-lb to 16 in-lb]. Reassemble cover and torque to
10 Nm [90 in-lb].
2.
Put cover locking clamp on circular cover and tighten the flat
head cross recessed screw to 1,5 Nm to 1,8 Nm [13.27 in-lb
to 16 in-lb]. (See Figures 9 and 10)

The internal grounding terminal must be used for the equip-
ment grounding connection, and the external terminal is for
