Each dimmer has three sets of lugs connected to phase,
neutral and earth. Phase and earth lugs are on the right side
of the rack, neutral lugs are on the left. Lugs can be single 6/
10/15/25 amp, paired 15/25 amp fluorescent, or double-
height 50 amp.
Step 1: Route the load wires to the rack(s).
Step 2: If using Multicore cable, strip back the sheath so
N o t e : When using ED15AFRF modules connected to
dimmable fluorescent 3-wire ballasts, wire the top
lug in each slot to the ballast’s non-dimmed power
lead and the bottom lug to the dimmed ballast
control lead.
C A U T I O N : Dress and terminate wires neatly and avoid leaving
extra wire inside the rack. Too much clutter
(especially along the right side of the rack) can
restrict air circulation and reduce cooling efficiency.
If cabling interferes with airflow during operation,
the rack may shut down due to overheating.
Load wires should not cross between racks. They
should enter the rack in which they will be
terminated.
Phase and neutral load wiring must follow the same
conduit/path for each circuit.
