Mounting The Power Supply...
While the ISP8HS Strobe/Halogen power supply will be mounted in the vehicle's trunk, the installation
technician should keep the following recommendations in mind:
A) The unit 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 power supply 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 ISP8HS to be exposed to water!
D) When routing the 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.).
Using appropriately sized wires, connect the power supply to the battery using the wiring diagram
on page 7 as a guide. Be sure to include the specified size fuse, keeping in mind that there should not
be more than two feet of wire between the fuse block and the positive battery terminal.
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!
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!
Using the hardware provided, secure the power supply to its mounting surface.
