ELECTRICAL INSTALLATION
2.4.1
ELECTRICAL REQUIREMENTS
GeminiG3 radiomodem is designed to operate from a 13.8Vdc nominal car battery (negative ground) and requires
currents up to 12.0A. It will tolerate a supply voltage range of 10.9 volts to 16.3 volts.
In vehicles with a 24 VDC electrical system (mostly in trucks), it is essential to provide a suitably rated 24/12 VDC
converter to isolate the unit from the battery and protect it against excessive voltage.
Warnings:
Always disconnect GeminiG3 radiomodem’s DC power lead before connecting a second battery, using
power from another vehicle or power boosting (e.g. when “jump starting” the vehicle).
2.4.2
ROUTING OF POWER CABLE
1.
Start by disconnecting the vehicle’s battery unless specifically prohibited from doing so by the customer,
vehicle manufacturer, agent or supplier.
Note:
In this event, exercise extreme caution throughout the installation and fit the fuse only
when the installation is complete.
