Honeywell Galaxy 3-48C Installation Instruction

The minimum capacity battery to supply the PSU is 1x 7Ah. The maximum capacity battery to supply the
PSU is 2 x 17Ah.

A battery test on full load is automatically performed once an hour and during the Engineer Mode exiting
procedure. If the battery voltage falls to 10 V while the Power Supply Unit is running on the battery, then it is
automatically disconnected to prevent deep discharge of the battery.
