Reconnect the neutral wire (L2) at the power source. Remove the test probe from the grounded
terminal and reconnect it to terminal L2 in the wiring base. With the other probe, touch each ter-
minal. It is normal to obtain a resistance reading on the meter at some terminals during this test
as there are resistive loads (coils-transformers-lamps, etc.) connected whose normal DC resis-
tance may be less than 5 ohms. However, at no time should the test meter read zero ohms.
4.
If either a ground or a short circuit is detected, it must be eliminated before the control is
plugged into the wiring base and power turned on. Otherwise, the control may be destroyed or
improper operation may occur.
INSTALLING THE CONTROL
CAUTION: Assure that electric power is shut off.
1.
Check the electrical tabs on the bottom of the chassis — if they are bent out of position, reposi-
tion them with your fingers using the angle on the bottom of the red tag shipped with the control
as a guide.
2.
Insert the slots at the bottom of the assembled control in the tabs on the wiring base. Push the
control into position. Insert a screwdriver through the hole in the top of the control and tighten
the retaining screw.
