When the temperature drops, the inverter will automatically return to normal operation.
IMPORTANT:
The cooling fan is designed to operate when the temperature increases but may
not be adequate enough to prevent overheating.

Fuse Replacement
This inverter is equipped with two replaceable 30 amp internal fuses. Never check or remove the
fuses when the inverter is connected to a DC power supply. Disconnect the inverter from the DC
power supply first. Remove the protective cover from the DC end of the inverter to identify a
blown fuse as shown below.
Replace the blown fuse with a new 30-amp fuse by aligning the two contacts on the fuse, with the
internal connections, as shown above.
Replace the protective cover once the fuse has been replaced.

ONSUMPTION
For each piece of equipment you will be operating from the inverter, you must determine the
battery’s reserve capacity (how long the battery can deliver a specific amount of current – in
automotive batteries, usually 25 ampere) or ampere-hour capacity (a measure of how many
amperes a battery can deliver for a specified length of time).
Example – Reserve capacity: a battery with a reserve capacity of 180 minutes can deliver 25
ampere for 180 minutes before it is completely discharged.
