Pendent Mount Installation Steps:
•
For maximum long term reliability and light output, the light must be installed in free air.
o
The Low 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 Low 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.
•
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
•
Restore power and verify operation.
Dialight Low Bay Variable Dimming:
The Dialight Low 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 Low 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.
Important Notes
•
The low voltage Dimming wires are connected to the grounded output section of the driver
inside the light. Never connect either one to the Hot or Neutral supply wires.
•
The ‘-‘ wire (Black) is at ground potential.
•
Never use these wires for any purpose other than dimming.
