WIRING INSTRUCTIONS

This Time Switch can be wired to control one to four circuits simultaneously on a seven
day schedule. Clock motor voltage may be other than load voltage, but must be as
specified. For terminal markings, internal wiring and contact arrangements refer to wiring dia­gram above. To form the common poles of a DOUBLE POLE DOUBLE THROW switch, if
required, install jumpers (extend supply wires) between terminals 1-6 and 3-8. Use solid or
stranded COPPER wire with insulation to suit installation. See table for gauge selection.
To make power connections remove 1/2 inch of insulation from wire ends. Insert bare ends
of wire under the pressure plate of terminals. Use 3/16 or larger screw driver to tighten
terminal screws firmly.

REPLACE FRONT INSULATOR BEFORE TURNING

ON ELECTRICITY.
