Fluorescent Load Wiring
3-wire Fluorescent
To control 3-wire fluorescent ballasts, the power circuit in the enclosure must be configured
as a fluorescent module type (D15F, D20F, AD15F, AD20F,HD25F), which is a single
density module, with a 2/3 wire fluorescent dimmer mode assignment. Reference the
related Architectural Control Processor Configuration Manual for instructions on changing
the dimmer mode.
Step 1:
Pull the three wire fluorescent ballast wiring into the DRd enclosure per the wire
entry plan.
Step 2:
Strip 5/8” (16mm) of insulation from the end of each load wire.
Step 3:
Terminate the black switched hot/live wire to the top terminal in its assigned
dimmer lug pair. Insert the wire between the back of the lug and the pressure
plate as shown.
Step 4:
Terminate the dimmed hot/live wire to the bottom terminal in its assigned dimmer
lug pair. Insert the wire between the back of the lug and the pressure plate as
N o t e :
When using D20FB modules, connected to dimmable fluorescent 2-wire ballasts
with integral battery backup, use the same terminations as listed in the 3-wire
Fluorescent instructions.
N o t e :
Even though two lugs are used, the configuration (as found in the Dimmer Setup
menu of the ACP) refers only to the top (odd) number lug.
