Installation

WARNING

To reduce the risk of ignition of hazardous atmospheres and shock, do not apply power to the unit 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 and Canadian Electrical Code.

NOTE: This unit must be mounted with the globe vertically facing up or down.

• 1. Mount using the following applicable method.
  • a. Pendant Mount Models (Figures 1 and 5): Unscrew the globe assembly from the mounting hood and set aside. Install explosion-proof hanger box (not supplied). Secure 3/4" (19 mm) NPT threaded conduit (not supplied) to the box. Install the hood on the conduit. Proceed to step 2.
  • b. Ceiling Mount Models (Figures 2 and 5): Unscrew the globe assembly from the ceiling mount box. Mount the ceiling box using appropriate hardware (not supplied) suitable for the mounting surface. Proceed to step 2.

• c. Bracket Mount Models (Figures 3 and 5): Unscrew the globe assembly from the wall bracket. Install the mounting bracket using appropriate hardware (not supplied) for the mounting surface. Pull the field wiring through the mounting bracket. Proceed to step 2.
• 2. Extend the required power source wiring down through the mounting hood. See Table 2 for required supply wire temperature ratings.
• Refer to Figure 5. Loosen the (2) screws holding the circuit block in place. Rotate and remove the circuit block.
• 4. Connect field earth ground wire to ground screw (Figure 5) or earth ground via conduit system.
• 5. Wire in accordance with Figures 4 and 5. The positive (+) terminal is gold colored and the negative (-) terminal is silver colored.
• 6. Replace circuit block and tighten two screws to hold in place.
• 7. Install the fixture on the mounting hood, bracket or box as applicable.

WARNING

To reduce the risk of ignition of hazardous atmospheres and shock, keep assembly tightly closed when circuits are energized.

8. Apply power to the unit and ensure proper function.

WARNING

To reduce the risk of ignition of hazardous atmospheres and shock, keep assembly tightly closed when circuits are energized.

Loosen the globe and ring assembly set screw. Insert a suitable tool into the notches in the globe and ring assembly and loosen the assembly by prying in a counterclockwise direction. Remove the ring and globe assembly.

• 3. Refer to Table 1 for the correct replacement catalog number and replace the necessary part.
• 4. To replace, simply screw the unit on until it seats firmly onto its gasket. Tighten the unit another 1/8 to 1/4 turn. Tighten the setscrew.
• Reinstall the guard, where applicable, and secure using the three supplied screws.
• 6. After the unit is assembled, apply power and make sure the unit functions properly.
