INSTALLING THE 21.7690

1. Physical Mounting

Mount the power supply in a clean, dry location. Mounting the
unit to a flat metal surface will aid in heat dissipation. Use the
power supply as a template to mark the hole locations. The
mounting holes will accept up to a 1/4" bolt.
supply baseplate must be connected to chassis ground (GND) to
reduce radio interference.

2. Strobe Head installation

Plug the strobe light heads into the outlets. Keep the following in
mind:
• Heads connected to outlets 1, 3, 5 flash at the same time.
• Heads connected to outlets 2, 4, 6 flash at the same time.
• Heads connected to 1, 3, 5 alternate with heads 2, 4, 6.
The output power
installed. Example: 90 Watts into 2 heads = 45 Watts per head.
Consider this before selecting the number and type of strobe
heads to install. Do not exceed the wattage rating of the head.
Note: This supply reduces output power when only 2 outlets are activated.

3. Electrical Hookup

If you have purchased a pre wired switch harness, follow the
included instructions. If you are wiring the system yourself
follow the instructions below and the diagrams on the next page.
POWER HARNESS
• Connect the RED wire to battery positive (+) or a fuse panel
circuit rated for at least 15 AMPS.
• Connect the BLACK wire to battery negative (-) or directly to
vehicle chassis.
Note: Use the correct size wire for power connections.
The length of the wires determines the size needed.
• The VIOLET wire controls HIGH / LOW power. Low power
limits the flash intensity for nighttime use. Connect VIOLET to
+12/24V for LOW, leave VIOLET disconnected for HIGH.
