Notice!
This WPPS690 strobe power supply, like all
Whelen components, can be installed in many different
types of vehicles. The guidelines for the installation of this
product are written so that no matter what vehicle is being
used, the installation and operation of the WPPS690 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 WPPS690 could be installed,
this is not always possible. The following guidelines will help
the installer select an acceptable alternative:
A) The WPPS690 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 WPPS690 will be
exposed to potential damage from any unsecured or
loose equipment in the vehicle.
C) When routing the WPPS690's 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 WPPS690 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!
1. Position the WPPS690 in its proposed mounting
location to ensure that it fits properly. With the
WPPS690 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 WPPS690 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 WPPS690 to its mounting location and using
the supplied #10 sheet metal screws, mount the WPPS690
onto its mounting surface.

Wiring your WPPS690:

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 bat-
tery.
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. 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.
