How to Install the 371DST Strobe Light

This guide provides step-by-step instructions for installing and wiring the 371DST Strobe Light in hazardous locations.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Drill, Multimeter

Supplies needed:

Mounting screws, Terminal connectors, 1” NPT conduit hub, 1” NPT close-up plug

  1. Unpack and Inspect the Light

    Carefully unpack the 371DST Strobe Light and inspect it for any damage that may have occurred during transit. If damaged, do not install and file a claim with the carrier.

  2. Mount the Light

    Choose a flat horizontal surface or a 1” NPT pipe for mounting. For surface mounting, use the gasket as a template to mark four drill positions. Drill holes for mounting screws and a larger hole for wire entry. Secure the light using the provided screws and washers.

  3. Make Electrical Connections

    Disassemble the light by removing the dome assembly and the strobe-spinning assembly. Route the supply wires into the housing, strip 0.28” of insulation from the ends, and connect them to the terminal block, ensuring proper polarity for DC models. Connect the earth ground to the terminal block.

  4. Reassemble and Test the Light

    Reassemble the light by securing the strobe-spinning assembly and dome. Ensure the dome is tightly closed. Turn on the power and test the light to ensure it operates correctly.
