Notice: 

This UPS69024 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 UPS69024 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 
variety of vehicles onto which the UPS69024 could be 
installed, this is not always possible. The following guide-
lines will help the installer select an acceptable alternative:

A)

The UPS69024 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 UPS69024 will be 
exposed to potential damage from any unsecured or 
loose equipment in the vehicle.

C)

Be sure the area selected will not allow the UPS69024 
to be exposed to water.

D)

When routing the UPS69024’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.).

E)

When the best mounting location has been determined,
securely fasten the UPS69024 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 mount-

ing surface, the installer MUST be sure that no vehicle com-
ponents or other vital parts could be damaged by the drilling 
process. Check both sides of the mounting surface before 
drilling begins.

Mounting your UPS69024:

1.

Position the UPS69024 in its proposed mounting loca-
tion to ensure that it fits properly. With the UPS69024 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 UPS69024 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 UPS69024 to its mounting location and using 
the supplied #10 sheet metal screws, mount onto its 
mounting surface.

Wiring your UPS69024:

1.

Locate the 10 position 

Input Connector

 included with your 

UPS69024 and plug it into the port indicated in Fig. 1.
Extend the BLACK and RED wires from the 

Input Connec-

tor

 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. 2 for wiring information for the remaining 

Switch Control Wires 

and 

Pattern Control Wires

5.

As indicated in Fig. 2, there is a provision in the 

Input

Connector

 for a wire (VIOLET) to activate Hi Power/Low 

Power strobe operation. If this feature is desired, locate the 
VIOLET wire included with your power supply and, with the 

Input Connector

 disconnected from the power supply, 

insert the pinned end of the VIOLET wire into position 4 of 
the 

Input Connector

. Refer to the Wiring Diagram on page 

3 for wiring information.

Configuring your UPS69024:

Although the wiring diagram illustrates the proper switch con-
nections for the UPS69024, an explanation of how the switches 
are configured is necessary. It is also necessary to understand 
how the dip switch positions will impact the operation of the 
UPS69024. The following section will explain switch functional-
ity in the DEFAULT configuration (all dip switches in the OFF 
position and all strobe switches wired as illustrated).

Strobe Switches:

Switch #1 (SW1) -

 In the default configuration, switch 1 controls 

outlets 1 & 2. The control wire for switch 1 is the BLUE wire.

Switch #2 (SW2) -

 In the default configuration, switch 2 controls 

outlets 3 & 4. The control wire for switch 2 is the GREEN wire.
