1. Mounting:
Mount the power supply to a flat metal surface.
Mount in a clean, dry area. NEVERMOUNTINENGINECOMPARTMENT!
Use the power supply as a template to mark the hole locations.
The mounting holes will accept up to a 1/4"bolt.
Note: Thepower supply baseplate must be connected to chassis
ground (GND) to reduce radio interference.
2. Strobe Head Installation:
Plug the strobe head extension cables into the outlets.
.Heads connected to outlets I and 3 flash at the same time.
.Heads connected to outlets 2 and 4 flash at the same time.
.Heads connected to I and 3 alternate with heads 2 and 4.
.Be sure to use strobe heads with the correct power rating.
The total output power (60 Watts) of the MODEL 21.7462 is
distributed to the strobe heads as follows:
I Head installed and activated = 30 Watts.
2 Heads installed and/or activated = 30 Watts per head.
3 Heads installed and/or activated = 2 heads at 15Watts each, 1...&.J.QJYa1ts.
4 Heads installed and/or activated = 15Watts per head.
3. Electrical Hookup:
If you have purchased a switch panel, follow the included
instructions. If you are wiring the system yourselffollow the
instructions below and the diagrams on the next page.

POWER HARNESS:
.Connect the RED wire to BATTERY + through a 15A fuse
(customer supplied) located at the battery.
.Connect the BLACK wire to battery negative (-) or directlyto
vehicle chassis.
Note: Usethe correct size wirefor power connections. Thelength
of the wires determines the size needed.
1to lOft. use 18AWGwire.
10 to 20ft. use 16A WG wire.
20 to 35ft. use 14AWG wire.
35 to 50ft. use 12AWGwire.
.The VIOLET wire activates LOW power mode. The output
power is reduced to 40 Watts in LOW power mode. Connect
VIOLET to + 12/24V to activate LOW power mode, leave
disconnected or connect to GROUND for high power mode.

CONTROL HARNESS:
UJLL<C»W: Flash pattern selection. Momentarily connect to
+ 12/24V to advance to the next flash pattern in the PATTERN
LIST. Momentarily connect for 3 seconds to reset to pattern #1.
The flash pattern will be retained when the MODEL 21.7462 is
turned off or if power is removed. To change flash patterns
frequently, connect UJLJL<C»Wto a momentary pushbutton located
in the passenger compartment.
GREEN: Activates Heads 1 and 2 when connected to + 12/24V
BLUE: Activates Heads 3 and 4 when connected to + 12/24V
NOTE: VIOLET, YELLOW, GREEN, and BLUE are all Low Current circuits and
can be wired with a minimum of 18AWGwire.

DIAGNOSTIC INDICATORS
The MODEL 21.7462 is equipped with two
diagnostic indicators located on the PC board
directly below the EZ PANEL connector.
If the MODEL 21.7462 has stopped functioning
check the diagnostic lights and follow the
IN~Y6~foR INg:6~;OR instructions below.
I.'OUTPUT INDICATOR (RED)
NORMAL: The OUTPUT INDICATORwill light when ANY strobe
head fires. It will blink in exact time with the flash pattern. When the
MODEL 21.7462 is turned off the indicator may dimly blink for a few
seconds. This indicates that the power supply is discharging itself.

PROBLEM: If the MODEL 21.7462 is activated but none of the strobe
heads are firing, check the OUTPUTINDICATOR.If the light is
blinking or on steady then it indicates that there is a short circuit on one
or more of the strobe head outputs.
To find the short circuit, unplug all strobe head cables from the
MODEL 21.7462. Test one cable/head at a time until the problem is
found. Do not test with more than one cable/head installed.
The problem is typically at the strobe head end of the cable. If there is a
blue/green orblack colored corrosion on the connector it is shorted.
Also checkfor a head or cable with a reverse wired connector.

mIINPUT INDICATOR (GREEN)
NORMAL: The INPUT INDICATOR should NOT be lit during
normal operation. It may blink for a second when power is first applied
to the MODEL 21.7462, or when power is removed but this does not
indicate a problem with the power supply.

SELECT PROBLEM: If the MODEL 21.7462 is activated but none of the strobe
heads are firing, check the INPUT INDICATOR. If it is ON then it
indicatesthat the input voltage is too low (below IOY).
Theremay be a bad connection to the battery or ground.
If the MODEL 21.7462 is functioning but the INPUT INDICATORis
blinking or lit it indicates that the voltage is too low and the power
supply is not operating at full power. Check for bad connections and be
surethe proper size wire was used for the + and - connections.
DI:I BLOWN FUSE
TheMODEL 21.7462 will blow a fuse if the input voltage is reversed.
If this happens, fITStlocate the wiring fault, then replace the fuse with
oneof the same rating. If the fuse continues to blow it indicates an
internalfault. Do not use a fuse larger than 15A!
EZ PANEL CONNECTOR
.The EZ PANEL connector is only for use with the EZ
PANEL series of control panels.
.Do not connect both the EZ PANEL cable and the
standard control wires at the same time!
.Do not connect any other devices to the EZ PANEL
connector as permanent damage may result.
.Use only approved cables with the EZ PANEL.
