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.
Mounting your WPPSC694...
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 WPPSC694 in its proposed mounting location to ensure that it fits
properly. With the WPPSC694 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 WPPSC694 from its mounting area and, using an appropriately sized
drill bit, drill a hole in each of the areas scribed in the previous step.
3. Return the WPPSC694 to its mounting location and using appropriately sized
hardware, secure the WPPSC694 to its mounting surface.
Wiring your WPPSC694...
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.
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.
Important!!!
The Deutsch water-proof connector will not function properly unless it is
connected exactly as the manufacturer intended. A Deutsch crimping tool

(Whelen p/n 66T0516435119C) is required for proper terminal crimping and
should be used whenever possible. Whelen Engineering does not recognize
the use of a non-Deutsch crimping tool, therefore any resulting damage would
void the warranty.
Assembly...
1. Locate the 3-conductor cable (customer supplied) that will be used to connect
Lamps L1 & L2 to Plug #1 of the WPPSC694.
2. Crimp the "pin"-style wire terminals (included) onto the power supply end of the
wires.
3. Using the Plug #1 table as a wiring guide, insert the terminals into one of the
receptacles (included). Note: The wire colors shown connected to the receptacles
(in the wiring diagram), represent the Whelen color codes for their strobe lamps.
Make sure to use the wire function as a guide to proper terminal location.
4. Hold the receptacle so that the rear grommet is facing you.
5. Push the pin straight into the grommet until a "click" is felt. A gentle tug will
confirm that it is properly locked into place.
6. Once all the pins are installed, insert the orange wedge into the receptacle.
7. Repeat the above procedure for plugs #2 and #3.
NOTE: Although the above text outlines the procedure for assembling the strobe
plug receptacles, the same procedure is used for the Input Control plug. The plug
section utilizes a faceplate instead of a wedge. It can be removed with a small screw-
driver.
8. Locate the 7 conductor cable (customer supplied) that will be used to connect the
WPPSC694 to its control switches and to a power source (vehicle battery).
9. Crimp the "socket"-style wire terminals (included) onto the power supply end of
the wires.
10.Using the input control table as a guide, insert the terminals into the Input Control
Plug (included). Note: The wire colors shown connected to the Input Control Plug
(in the wiring diagram), represent the Whelen colors & functions found in the input
control harness. Make sure to use the wire function as a guide to proper terminal
location and wire connection.
