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.
