and Canadian Electrical Code.
1. Mount using the following applicable method.
a. Pendant Mount Models (Figure 2): Install the
catalog number 116EX-P, pendant mounting
module, to the main housing. Install explosionproof hanger box (not supplied). Secure 3/4" (19
mm) NPT threaded conduit (not supplied) to the
box. Install the unit on the conduit. Proceed to
step 2.
b. Ceiling Mount Models (Figure 3): Mount the
catalog number 116EX-C, ceiling/wall mounting
module, using appropriate hardware (not supplied)
suitable for the mounting surface. Proceed to step
2.
c. Bracket Mount Models (Figure 4): Install the
catalog number 116EX-C ceiilng/wall mounting
module using appropriate hardware (not supplied)
for the mounting surface. Install the catalog
number 116EX-B wall mounting elbow to the wall
box. Run the unit's wiring through the elbow to
the wall box. Proceed to step 2.
d. Stanchion Mount Models (Figure 5): Install the
catalog number 116EX-S, stanchion mounting
module, to the main housing. Run the unit's wires
through the 1 1/4" conduit to the appropriate
junction box. Install the unit on the conduit.
Proceed to step 2.
2. Connect field earth ground wire to ground screw or
earth ground via conduit system.
3. Wire the unit in accordance with Figure 6. See Table
2 for required supply wire temperature ratings.
4. As appropriate, install the fixture on the mounting
module.
WARNING
To reduce the risk of ignition of hazardous atmospheres and shock, keep assembly tightly closed
when circuits are energized.
5. Apply power to the unit and ensure proper function.
