Circuit diagram is shown on the nameplate. To mount either switch, merely tighten mounting screws, tighten plug-in unit or cover screws, and make sure It will be easier to wire the double- conduit section is sealed. Use of sealant (teflon tape, pole units by connecting lead wires to pipe dope, etc.) is recommended to seal conduit the terminals nearest the conduit opening first. A connection. grounding screw is located in the housing near the conduit opening.

Wires can be unsoldered and reconnected to the normally-closed male terminals or they can be ordered connected to the normally-closed terminals by using a modification code (refer to Catalog 40). Always connect these wires to the same set of terminals used for the load. Across the normally open male terminals ( 3 and 4) the light will be On (Fig. 1). Across the normally closed terminals ( 1 and 2) the light will be Off. Single-Pole Plug-in Type Double-Pole Non Plug-in Type Sensing and Control HDLS Series Issue 2 81116 ADJUSTING INSTRUCTIONS 4.
