PROCEDURES
WARNING
HIGH VOLTAGES ARE PRESENT. TURN OFF POWER
BEFORE INSTALLATION OR
SERVICING.
The use of temporary ground during installation and maintenance is recommended .
1) Install one washer over the threads at the end of the SP-36 housing. Push the washer
up against the housing.
2) Choose a knockout in the load center that is a distance from the backboard that
will
allow the back of the SP-36 to lay flat against the backboard.
3) Install the second washer on the threads at the end of the SP-36 housing from
inside
the load center . Install the lock nut so that it loosely holds the SP-36 in place.
4) Use the wood screw provided to secure the SP-36 mounting tab to the
backboard .
5) Tighten the lock nut installed in step 3 for a snug
fit.
Cut the wires on the SP-36 to the minimum usable
lengt h . Do not coil the wires as this
greatly reduces SP-36 performanc e . Also, avoid kinks and sharp bends in the wiring .
7) Connect the wires to the load center, observing the proper hook-up
scheme.
8) The wires must be connected so that there is a fuse or circuit breaker between the
SP-
36
and the power service line.
