Installing the External DC Power Module
You must be a qualified mechanic or electrician to install the power module. If the
cable provided for input to the External Power Module is not long enough, make
sure that you use 14 gauge or larger wire to extend the cable.
Incorrect polarity connection will cause fuse to open.
CAUTION
Figure 11-3
Connection of External Power Module
The External Power Module can be connected to any 12 Volt negative ground
source. The circuit which supplies power to the external power module should be
protected by a fuse between 10 amps and 20 amps. This allows sufficient power to
operate the External Power Module and still provides electrical protection in case of
faulty or defective wiring to the External Power Module.
The power module attempts to draw power from the vehicle 12 Volt system
whenever the defibrillator/monitor is on and whenever the defibrillator/monitor
battery is charging. If you do not want power drawn from the vehicle when the
vehicle is not running then install the External Power Module so that it is electrically
disconnected when the vehicle is off.
