Fuse
A fuse is required in order to protect the wiring. 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. For
12V operation, use a 15A fuse, and for 24Voperation
use a 7.5A fuse.

ATTENTION:
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 9.6V (in 12 V mode) or 21.3V
(in 24 V mode), the compressor will shut-off. Once
the voltage increases above 10.9V (in 12V mode) or
22.6V (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.
