Intermatic T100 Series Instruction Sheet

WARNING Risk of Fire or Electric Shock
• Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.
• Installation and/or wiring must be in accordance with national and local electrical code requirements.
• Use wires rated at least 90°C - COPPER conductors ONLY.
• Replace plastic insulator covering terminals before powering ON.
• KEEP DOOR CLOSED AT ALL TIMES when not servicing.

Programming Instructions:

1. TO SET "ON" AND "OFF" TIMES: Hold trippers against edge of CLOCK-DIAL, pointing to time (AM or PM) when ON and OFF
operations are desired, tighten tripper screws firmly. For additional tripper pairs on CLOCK-DIAL order 156T1978A.
2. TO SET TIME-OF-DAY: Pull CLOCK-DIAL outward. Turn in either direction and align the exact time-of-day on the CLOCK-DIAL
(the time now, when switch is being put into operation) to the pointer. DO NOT MOVE POINTER.

Operating Instructions:

• TO OPERATE SWITCH MANUALLY: Move MANUAL LEVER below CLOCK-DIAL left or right as indicated by arrows. This will not
effect next operation.
• IN CASE OF POWER FAILURE, reset CLOCK-DIAL to proper time-of-day. See programming instructions.

NORMALLY CLOSED, move clock motor lead from terminal 3 to 1, and connect LINE to 1,
LOAD to 2. To wire as SINGLE POLE DOUBLE THROW, install jumper (the same gauge
as line wire) between 2 and 3 and connect LINE to 2, LOADS to 1 and 4. NOTE: Line 2 if
present is uninterrupted.
