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. As a result, light output
may be reduced.
•
The High Bay fixture is threaded for 3/4” NPT in order to be assembled to conduit.
o
Calculate and measure required conduit length.
o
Feed the power cable through the conduit and into the junction box.
o
Attach the fixture to the conduit (using Teflon tape or pipe sealant).
o
Insert 1/4-20 anti-rotation screw in order to secure the fixture to the conduit.
o
Note: For Model Numbers HB6C4Y and HB7C4Y only, alignment bar on top of fixture
corresponds to major axis of the “narrow oval” light pattern.
•
Connect power cable conductors as follows:
o
Green wire connects to Safety Ground.
o
White wire connects to Neutral
o
Black wire connects to Live
•
Remove protective film (if present) from the High Bay fixture lens.
•
Restore power and verify operation.
Dialight High Bay Variable Dimming:
The Dialight High Bay fixture supports variable dimming through a two wire interface. Using this interface,
it is possible to reduce the light level of the fixture, saving energy and setting the level exactly as desired.
The dimmable High Bay has a two cable (five wires total) interface. The power cable houses two wires
which are used to power the unit (Black and White, Hot and Neutral, respectively), and one which is used
as a safety ground/Earth (Green). The other cable houses two wires (Red and Black) which form the
dimming interface and can be used in the ways described below.
