Power
The PVSG-IQAN is powered by a direct battery connection. The gateway is turned
on by applying power to the power control input.
The PVSG-IQAN operates in a 12 V or 24 V system and can operate from 6.5 V up
to 32 V with over-voltage protection at 36 V.

Recommended External Fuse - 3 - A
Note 1: It is strongly recommended that Pin 6 of the module be connected
directly to the vehicle battery source and to utilize Pin 11 (Keyswitch) for
activating and deactivating, as well as allowing a safe shut-down sequence of
the module. Connecting Pin 6 to a switched battery source may result in
memory corruption which, in its most severe case, may render the unit
inoperable and require device reprogramming to recover. It is recommended
to cycled power the gateway frequently with an ignition power source.
Note 2: Exposure to maximum voltages for extended periods may affect
device reliability.
Note 3: Maximum peak current is a theoretical calculation assuming maximum
current draw for each peripheral as specified in datasheets, 85% efficiency for
step-down regulators, and peak cellular current during a 1-slot Tx burst at
maximum power. Note the burst duration is typically 1 ms or less, thus not
affecting recommended fuse ratings.
