Installation

WARNING

To prevent electrical shock, do not connect power until installation has been completed and unit is tightly assembled and secured.

Install this unit in accordance with the applicable requirements in the latest edition of the National Electrical Code. See the unit's label and Table 1 for specifications.

NOTE: For indoor applications, the strobe light can be mounted vertically either facing up or facing down. For outdoor applications, the unit must be mounted vertically with the lens facing up.

• 1. Pull appropriate power source wiring through 3/4" (19 mm) NPT conduit. Install the unit on the conduit.
• Connect red positive (+) lead to positive power source wire and black negative (-) lead to negative power source wire. Polarity must be observed on 24V DC unit. For AC units, connect green ground wire to earth ground.

3. Apply power to the unit and ensure proper operation.

Maintenance

Strobe Tube Replacement

WARNING

To prevent electrical shock, disconnect from the supply circuit and allow five (5) minutes for stored energy to dissipate before disassembling the unit.
