This WPPS6924 Strobe Power Supply . . .
Like all Whelen components, the WPPS6924 can be
installed in many different types of vehicles. The guide-
lines for the installation of this product are written so that
no matter 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 WPPS6924 should be mounted on a metal sur-
face 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 vehi-
cle.
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 deter-
mined, securely fasten the unit to it's mounting sur-
face 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 dam-
aged by the drilling process. Check both sides of the
mounting surface before drilling begins!

Installation . . .
1. Position the WPPS6924 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 WPPS6924 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 WPPS6924 . . .
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 sup-
plied) and then to the POSITIVE terminal on the battery.
NOTE! Although a 15 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.
However, 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.
