When selecting a mounting location for the power supply unit, it is necessary to
keep in mind that the cables are available in 10, 16, 22, 30-foot lengths. See table 2
for a list of available parts. Plan all wiring and cable routing before performing
any installation. Also, this power supply creates heat when in operation. Select a
location where there is air circulation.
Before proceeding with electrical connections, it is important to understand the
operation of the unit. Outlets 1 & 3 and 2 & 4 form pairs of alternately flashing
strobe heads. The output cables are labeled for your convenience.
Powering multiple devices with a common control lead may cause one or more
units to briefly remain functional after signal power is removed. For example,
due to the high input filter capacitance, a strobe supply can briefly supply the
current required to operate a low current device such as a Cuda TriOptic™. If
necessary, use a relay to isolate devices with large filter capacitors. See figure
1 for the schematic; all components/wires are user-supplied.
1.
Disconnect vehicle battery. Ensure that power is disconnected from all vehicle
lighting control systems.
2.
Use the power supply as a template and scribe four drill positioning marks at
the selected mounting location.
3.
Drill four 0.136" diameter mounting holes at the position marks. This is a #29
drill bit.
4.
Install the strobe units as described in the instructions packed with the units.
Route the cables to the location of the power supply.
5.
Connect the black wire to a known good vehicle chassis ground. Allow enough
wire to dress the wire neatly, allowing for a drain loop and maintenance.
6.
Connect the red to a switched, 12/24 volt power source (switch, relay, or
vehicle lighting controller) capable of supplying 8.0 amperes. This wire should be fused
with an 8-amp fuse, as close to the positive battery connection as possible. Allow
enough wire to dress the wires neatly, allowing for drain loops and maintenance.
7.
If the cut-off feature is desired, the white/red cutoff wire can be connected to
a switch that will provide positive 12/24 volts, or can remain not connected if cut off is
not desired.
8.
Choose the pair of heads that should remain flashing when cutoff is acti-
vated. Front or rear cutoff is determined by the location of strobe heads connected to
outlets 2 and 4. The other pair of heads connected to outlets 1 and 3 will remain
flashing when cutoff is activated. To activate cutoff, apply +12/24Vdc to the 18AWG
white wire with red tracer.
9.
Install the strobe heads and cables. Refer to the instructions supplied with
the units, or cable kits, for additional wiring instructions. Route the cables to the strobe
tube units. Allow enough extra cable length for drain loops and maintenance.
10. Check all connections and wiring. Ensure that there are no short circuits and
that all wires are protected from any sharp edges. Reconnect the vehicle battery. Test
