Pendent Mount Installation Steps:
• For maximum long term reliability and light output, the light must be installed in free air.
o The High Bay fixture design incorporates an over-temperature control circuit that
reduces input power should internal temperatures reach a maximum level. In this
event, light output may be reduced.
• The High Bay fixture is threaded for 3/4” NPT in order to be assembled to conduit.
o The necks of these fixtures are filled with Chico in accordance with the C1D1
explosion proof regulation (Chico can not be seen from ¾” NPT entrance). Plan
your Chico fittings and conduit accordingly.
o Calculate and measure required conduit length.
o Feed the power cord (max length of power cord = 10’) through the conduit and into
the junction box.
o Attach the fixture to the conduit using conductive pipe sealant.
o Tighten 1/4-20 anti-rotational screw in order to secure the fixture to the conduit.
• Connect power cable conductors as follows:
o Green to Safety Ground.
o White to Neutral
o Black to Live
• Restore power and verify operation.
Interfacing to an Occupancy Sensor:
The Dialight High Bay fixture is ideally suited for control by an occupancy sensor in order to
maximize energy savings based on its instant-on behavior and low power consumption.
Instructions for connecting the High Bay fixture to an occupancy sensor are listed below.
WARNING: TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE
