IN-LINE FUSE
A 15A in-line fuse is provided with this freezer in order to protect the wiring.
For 12V/24V
operation, use a 15A fuse.
A standard automobile fuse is recommended and the fuse should be
wired to the positive (“+”) side of the system close to the positive battery terminal.
A 15A fuse is provided with this freezer.

If a longer connection cable is necessary, the cable cross section (or gauge) must be equal to or
greater than the cable sizes recommended on the following table. Be careful that the input voltage
at the appliance does not drop below the cut-out voltage of the compressor.

LOW VOLTAGE DISCONNECT
The compressor electronics includes a low voltage disconnect feature. If the input voltage to the
appliance falls below 10.4V (in 12V mode) or 22.8V (in 24V mode), the compressor will shut-off.
Once the voltage increases above 11.7V (in 12V mode) or 24.2V (in 24V mode), the compressor will
resume normal operation.
This feature is designed to protect the system battery from experiencing too low a depth of
discharge.
