This WPPS6922 Strobe Power Supply . . .
Like all Whelen components, the WPPS6922 can be
installed in man
y
different t
y
pes of vehicles. The
g
uidelines
for the installation of this product are written so that no mat-
ter what vehicle is bein
g
used, the installation and operation
of the unit will be simple and strai
g
ht forward.
Selecting a Mounting Location . . .
The most common choice for a mountin
g
area would be a
trunk or similar compartment. However, due to the wide vari-
et
y
of vehicles onto which the unit could be installed, this is
not alwa
y
s possible. The followin
g
g
uidelines 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
g
enerates or is exposed to excessive
heat durin
g
normal operation of the vehicle.
B) Do not select a location where the unit will be exposed
to potential dama
g
e from an
y
unsecured or loose
e
q
uipment in the vehicle.
C) When routin
g
the wires, it is important to choose a path
that will keep these wires awa
y
from excessive heat
and from an
y
vehicle e
q
uipment that could compromise
the inte
g
rit
y
of the wires
(
ex. trunk lids, door
j
ams, etc.
)
.
D) When the best mountin
g
location has been determined,
securel
y
fasten the unit to it’s mountin
g
surface usin
g
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 mountin
g
location to ensure that it fits properl
y
. With the unit in
place, insert an awl or other suitable tool into the
mountin
g
screw area of the power suppl
y
and scribe
the areas that are to be drilled.
2. Remove the
WPPS6922
from its mountin
g
area and, usin
g
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 suppl
y
to its mountin
g
location and usin
g
the supplied #10 sheet metal screws, mount the unit onto
its mountin
g
surface.
Wiring your WPPS6922 . . .
1. Locate the 8 position Input Harness Plu
g
and connect as
indicated in Fi
g
. 1. Extend the BLACK and RED wires from
the Input Harness Plu
g
towards the batter
y
.
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 batter
y
.
NOTE!
Althou
g
h a 7.5 amp fuse
(
customer supplied
)
is re
q
uired
to be used in the fuse block,do not install thefuse until
all
of the
wire connections are completed.
3. Connect the
BLACK
wire to the factor
y
chassis
g
round
ad
j
acent to the batter
y
.
4. Refer to Fi
g
. 1 for detailed wirin
g
information.
Correct use of the Water-Proof Butt Splice . . .
Water-proof Butt Splices have been included with
y
our
power suppl
y
. The proper use of these splices will help
prevent premature corrosion of
y
our strobe connections. How-
ever, the effectiveness of these splices is directl
y
related to their
proper installation.
Splice the two wires to
g
ether as would be done with a
re
g
ular butt splice. After the wires have been crimped, pass a
heat
g
un over the splice until the outer tubin
g
shrinks around
the wires, thus water-proofin
g
the connection. Be sure to keep
the heat
g
un movin
g
over the splice to prevent burnin
g
the
connector.

Switch Operation Table
Applying 24 VDC to the VIOLET
wire activates Lo Power operation
mode. The power supply is now effec-
tively “latched” into this mode. To
restore normal, High Power operation,
it is necessary to turn the power supply
off, and then on again. When the
power supply restarts, it will be in its
normal, High Power operating mode.
