This WPPS6922 Strobe Power Supply . . .
Like all Whelen components, the WPPS6922 can be
installed in many different types of vehicles. The guidelines
for the installation of this product are written so that no mat-
ter what vehicle is being used, the installation and operation
of the unit will be simple and straight forward.
Selecting a Mounting Location . . .
The most common choice for a mounting area would be a
trunk or similar compartment. However, due to the wide vari-
ety of vehicles onto which the unit could be installed, this is
not always possible. The following guidelines will help the
installer select an acceptable alternative:
A) The WPPS6922 should be mounted on a metal surface
to aid heat dissipation. Be sure that this surface is not
one that either generates or is exposed to excessive
heat during normal operation of the vehicle.
B) Do not select a location where the unit will be exposed
to potential damage from any unsecured or loose
equipment in the vehicle.
C) When routing the wires, it is important to choose a path
that will keep these wires away from excessive heat
and from any vehicle equipment that could compromise
the integrity of the wires (ex. trunk lids, door jams, etc.).
D) When the best mounting location has been determined,
securely fasten the unit to it's mounting surface using
the supplied hardware.
WARNING: The Strobe Light Power Supply is a high voltage
device. Do not touch or remove tube assembly in strobe
light head assemblies while in operation. Wait 10 minutes
after disconnecting the unit from its power source before
starting work or troubleshooting on power supply or system.
CAUTION: As it will be necessary to drill holes into the
mounting surface, the installer MUST be sure that no vehicle
components or other vital parts could be damaged by the
drilling process. Check both sides of the mounting surface
before drilling begins!
Installation . . .
1.
Position the WPPS6922 in its proposed mounting
location to ensure that it fits properly. With the unit in
place, insert an awl or other suitable tool into the
mounting screw area of the power supply and scribe
the areas that are to be drilled.

2. Remove the WPPS6922 from its mounting area and, using
a drill bit sized for a #10 sheet metal screw, drill a hole in
each of the areas scribed in the previous step.
3. Return the power supply to its mounting location and using
the supplied #10 sheet metal screws, mount the unit onto
its mounting surface.
Wiring your WPPS6922 . . .
1. Locate the 8 position Input Harness Plug and connect as
indicated in Fig. 1. Extend the BLACK and RED wires from
the Input Harness Plug towards the battery.
WARNING: All customer supplied wires, that connect to the
positive (+) terminal of the battery, must be sized to supply at
least 125% of the maximum operating current, and fused "at the
battery" to carry the load!
2. Connect the RED wire to a fuse block (customer supplied)
and then to the POSITIVE terminal on the battery.
NOTE! Although a 7.5 amp fuse (customer supplied) is required
to be used in the fuse block, do not install the fuse until all of the
wire connections are completed.
3. Connect the BLACK wire to the factory chassis ground
adjacent to the battery.
4. Refer to Fig. 1 for detailed wiring information.
Correct use of the Water-Proof Butt Splice . . .
Water-proof Butt Splices have been included with your
power supply. The proper use of these splices will help
prevent premature corrosion of your strobe connections. How-
ever, the effectiveness of these splices is directly related to their
proper installation.
Splice the two wires together as would be done with a
regular butt splice. After the wires have been crimped, pass a
heat gun over the splice until the outer tubing shrinks around
the wires, thus water-proofing the connection. Be sure to keep
the heat gun moving over the splice to prevent burning the
connector.
