Land Load Wires
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.

Double-height 50 amp lug
Figure 2: Load lug types
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.
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.
Dual 15/25 amp lugs (fluorescent)
Dress and connect load wires
neatly without leaving extra
wire in the rack.
