Installation Instructions

Read Important Safety Information below before beginning installation.
Open the outer cover by pressing the clip.
Remove the interior protective cover by removing the two screws holding the cover in place (Figure 1).
Select the knockouts to be used. If you use the 1/2" knockout, carefully cut off the inner ring of the rubber plug with a knife (Figure 2). If you use the 3/4" knockout, please remove the entire rubber plug (Figure 3).
Place and mark the timer box in the desired mounting position. Install two screws at the mark and partially drive into place. Attach the Timer Box by placing screws over keyholes, then tighten screws.
Remove the screw to demount the motherboard (Figure 4).
Wire in accordance with national and local codes (see wiring diagrams below). Use copper wire AWG 8-18 suitable for 90°C (194 °F). Tighten all connections to a minimum of 10.6 lb. in. torque.
Grounding: Connect all grounding wires to the grounding lug at the bottom of the enclosure.
Reassemble the motherboard and interior protection cover.
Close the outer cover.

Important Safety Information

⚠ WARNING: Risk of Fire or Electric Shock. Read instructions thoroughly before installation and preserve for future reference.

Disconnect power at the circuit breaker and test if power is off before installing (or servicing) the Timer Box (more than one circuit breaker or disconnect switch may be required to fully disconnect power).

Wiring must be in accordance with all national and local electrical code requirements. Inspect all terminals and wires with a voltage meter before touching. The maximum total load to be controlled must not exceed the Timer Box capacity.

The Timer Box enclosure does not provide grounding between conduit connectors. When metallic conduit is used, you must also install grounding type bushings and jumper wires in accordance with National Electrical Code (NEC) requirements.
