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
(Power Control) 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.
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.
