The Fuse Distribution Rail Assembly has a DIN-type rail allowing additional Fuse Blocks to be added to
it if fuse expansion is necessary in the future, such as for multiple control head installations. The rail may
be cut to decrease its length if necessary, but enough room for at least one control head and any additional
future expansion should be considered first. Install the rail in accordance with the following procedure:
1.
Mount the Fuse Distribution Rail Assembly in the vicinity of the radio’s mounting location, but
where casual contact is not likely. Use self-threading screws (not supplied) and any available
mounting slots in the DIN rail to mount the block.
2.
Strip one end of the 10-AWG black wire (included with the Fuse Distribution Rail Kit) and crimp a
3/8-inch ring terminal to it.
3.
Near the Fuse Distribution Rail Assembly, locate an area of vehicle chassis ground within
approximately six (6) inches of the assembly and strip the area of any paint or dirt to expose a bare
metal surface.
4.
Drill a hole as necessary and connect the ring terminal to chassis ground. Use a self-threading screw
or other appropriate hardware to ensure a reliable metal-to-metal contact. Tighten securely.
5.
Cut the black wire to a length long enough to reach a green-yellow Grounding Block on the Fuse
Distribution Rail Assembly, plus length for a service loop. Strip the end to prepare it to connect to a
Grounding Block.
6.
The Fuse Distribution Rail Assembly has two green-
yellow Grounding Blocks. Each Grounding Block has
two wire-clamps with associated wire-clamp release
slots. As shown in the photo at the right, insert a #1 or
#2 flat-blade screwdriver completely into one of the
wire-clamp release slots. Insert the screwdriver until it is
captured in a vertical position as shown in the photo in
the next step.
