See figure 3-9. To protect the wire, 2
circuit breakers (CB1) rated at 50-amperes (Federal
Part No. 8474A176 or equivalent) should be con-
nected as close as practical to the positive (+) battery
terminal. When the total load current is greater than
50-amperes, use a 100-ampere circuit breaker. When
the total load current is less than 50-amperes, use a
50-ampere circuit breaker.
To use the Federal 50-ampere circuit
breakers (Part No. 8474A176) as a 100-ampere
circuit breaker, add the supplied jumper between the
two circuit breakers on the load side. DO NOT
remove the jumper on the battery side of the circuit
breakers.
WARNING
When making the following connections, never
exceed the current rating of the circuit break-
ers (CB1) near the battery (see figure 3-9).
Failure to do this will result in a shutdown of
the vehicle warning system.
5.
See figures 3-5 and 3-10. Connect
wires from the light bar or accessories to TB1-1
through TB1-3 or TB2-A through TB2-E as appli-
cable. All wire connections for TB2 will be made with
the right angle plug. (See face plate for relay designa-
tors.) Refer to the instructions packed with the light
bar or accessory for proper wire gauge, current
requirements, and any additional instructions. Do
NOT exceed fuse ratings shown in table 3-1.
CAUTION
NEVER exceed fuse current ratings. Installa-
tion of higher current fuses WILL damage the
unit and void the warranty.
The SS2000-LMS provides two terminal
strips (TB1 & TB2) for control of light bars, auxiliary
lights and accessories. A total of eight fused relay-
controlled outputs are available.
Each output switches a n12-volts
to the controlled device. Do NOT use the black wire
in the power cable for grounding the switched
device(s). Ground the switched devices separately.
Refer to the installation instructions
provided with the light bar or auxiliary light for
additional precautions and details.
IMPORTANT
Since the terminals labeled LIGHTS 1, 2, and 3
can be reprogrammed to activate in any of the
three modes, select the terminals used for the
various loads in accordance with the current
ratings of the terminals.
Primary rotating lights normally require more
current than flashing or secondary warning
lights. If, for example, primary rotating lights
are to be activated in Modes 2 and 3, connect
the rotators to LIGHTS 3 (rated at 40-amperes).
Then, reprogram the unit to activate the
LIGHTS 3 terminal in Modes 2 and 3.
Fuse current ratings and suggested uses for
each output are shown in table 3-1.
Complete the wiring to the light bar or
accessories as follows:
CAUTION
The relay board WILL be damaged if correct
polarity is not observed.
1.
Remove the chassis cover by loosening
the 2 screws on the bottom of the unit. Slide the cover
to expose the relay board and terminal strips.
2.
Route a #10AWG (minimum) red wire
through the hole lBAT and attach it to the
large lug-type terminal (LUG1) on the relay board.
The lug is accessible through the top of the unit via
the hole lBAT. Use a flathead screwdriver to
loosen and tighten this lug. Use a #8 AWG red wire if
the total light bar and auxiliary load currents exceed
50-amperes. Since this wire provides the power
source for all switched lighting functions, a good
mechanical and electrical connection here is impor-
tant.
3.
Route this wire through the previously
drilled hole into the engine compartment and
through existing clamps and holders toward the
battery. Do NOT make any connections to the battery
until all wiring is complete.

labeled FE, it can be isolated from the +12-volt battery
supply for switching other POSITIVE voltages.
