Follow these instructions to install the time switch.
1.
Open the time switch enclosure door.
2.
Remove and retain the screw that secures the plastic insulator.
3.
Lift the left side of the plastic insulator and pivot away to expose the terminal strip.
4.
Press the latch at the top of the enclosure and pull out the mechanism from the
enclosure.
5.
Choose and remove the selected knockout(s) from the enclosure.
NOTE: There are five 1/2 inch to 3/4 inch combination knockouts available. There are
two on the bottom of the enclosure, one on each side, and one on the rear. If a 3/4
inch knockout is needed, remove the 1/2 inch knockout first, then the 3/4 knockout.
6.
Place the enclosure in the desired location providing space for the enclosure door to
swing open fully.
7.
Securely mount enclosure using provided mounting holes.
8.
Use appropriately rated fittings for the installation.
9.
Snap the mechanism back into the enclosure.
10. Strip 1/2 inch off the supply and load wires. Use AWG #14 - #8 copper conductors
rated at least 105ºC. Torque to 15.6 lbf-in.
11. Connect the wires to the proper terminals on the time switch and tighten the screws
firmly (See wiring diagrams).
12. Connect ground wire to grounding terminal at the bottom of metal enclosures.
13. Return the insulator to its original position and replace the screw.
