The length measurement in the above table is from the battery to the refrigerator.
Protection:
This unit has an in built automatic low-voltage cutout system, designed to protect
your battery from discharging completely. This will automatically turn off the compressor when
the battery discharges to Cut-Out voltage (See table below). The compressor will automatically
restart when voltage increases to Cut-In (See table below).
IMPORTANT:
If your fridge cuts out prematurely, this may be due to the Battery Protection being
set too high. Consider lowering the battery protection level via the switch located
on the rear power panel.
