Charge Guard Wiring Diagram

Hughes recommends that a power management device (e.g.,
Charge Guard) be installed in the vehicle to prevent battery drain
and extend battery life.
Charge Guard features:

automatically turns mobile equipment On when you start
the engine

When you turn the engine Off, the equipment stays On
from 5 seconds to infinity depending upon the time
delay setting and the battery capacity

Turns equipment Off before preset time if battery
voltage drops too low

Figure 5-2 Charge Guard Features
Connect the Charge Guard in the ignition path to the 9450 as
shown below.
Note: IGN is low current and therefore less susceptible to
voltage drop during operation. The 9450 ignition input has a
hardware enforced power down mechanism to ensure that the
Charge Guard is effective in this application.
