STEP 4:
To begin wiring, remove power supply lid by
loosening six (6) M4 captive screws using a 3mm hex
driver.
Allow the captive fasteners to remain in the lid for
ease of re-installation.
The lid is secured with a retention cable.
STEP 5:
Supply connection to be made through one of 3
3/4-14 NPT entries on the luminaire. If using
Surface, Suspension or Yoke conguration, install
appropriate Listed 3/4” NPT cable gland for cable
size and be sure to follow all applicable local
electrical codes for the specic hazardous locations.
Torque cable gland base to manufacturer's
recommended specication. All unused entries
must be plugged with a NPT plug (two provided).
OR
Install Direct Rigid Conduit as per local electrical
code. For direct rigid conduit installation, torque
hand tight plus 2 to 3 turns
NOTE:
To aid in assembly and protection against ingress
use of a petrolatum or soap thickened mineral oil
based thread lubricant/sealant is necessary.
STEP 6:
Feed wire into Power Supply cavity.
Strip 100mm (4”) of cable casing and strip
conductors 8mm (0.32”).
NOTE:
If using cable, terminate the supply end in a suitable
Listed metal junction box using a suitable Listed
tting approved for installation location as required.
All eld wiring supply conductors shall be rated 90°C
minimum and rated for supply voltage (300V AC
Models, 600V HV models).
