2.7 Connecting the Power Source
The GSM/GPRS WorldTracker AVL has an input voltage range of 9 – 30 V DC. (See Table 3 and
Table 4). The power and ignition pins can support 9 – 30 V DC input voltage. The user has an option
to connect these wires depending on the desired functionality. Described below are the desired
functionality and their associated wire connecting procedure:
Use of the device outside of the specified voltage
!
range may result in damage to the device and/or
undesirable results.
