The “+12 INPUT” must be connected to the PSi through an AGC
2A in-line fuse. Although the PSi is internally fused, an additional
fuse should be placed as close to the 12V source as possible to
protect system wiring in the event of “short” to chassis ground
from a pinched power input lead. The PSi “GND” connection
should be securely attached to the car chassis ground using a
suitable lug to terminate the connection to bare metal. Bare wires
do not make adequate, permanent connections. The PSi “TURN
ON” can be connected to any switched 12V sources such as a
tape deck, “power antenna," or CD “switched to 12V output”.
ONLY wire sizes between AGW 12 and 22 gauge should be used
when making these connections. Strip 1/4 inch of insulation from
the end wire, insert into the proper position in the barrier strip and
tighten screw securely. It is always recommended that wiring be
securely terminated BEFORE APPLYING VOLTAGE. This will
eliminate the possibility of damage to the vehicle wiring by
shorting +12V to chassis ground.
PX TURN ON
PX “power up” is initiated by application of +12V to the “TURN
ON” terminal located on the plug-in barrier strip of the PSi. Note
that the PSi will not turn on unless the power cable is securely
connected to the DC INPUT connector on the rear of the PX Main.
The POWER indicators on the PSi and the PX should both
illuminate upon “power up”.
