4. Operation

4-1. Connecting the DC Cable

Connect DC input terminals to 12V / 24V /48V battery or other DC

power source [ + ] is positive, [ - ] is negative. Reverse polarity

connection can blow the internal fuse and may damage the

inverter permanently.

Figure 14. DC cable connection

Warning! Make sure that all the DC connections are

tight (torque to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose

connections could result in overheating and can be a

potential hazard.

Warning! The recommended inline fuse should be

installed as close to the battery positive terminal as

possible failure to use a fuse on the “+” cable running

between the inverter and battery may cause damage

to the cable / inverter and will void warranty.

Also, only use high quality copper wire and keep the cable length

short which is a maximum of 3 - 6 feet.

4-2. Connecting the Input Power

Before making the DC input side connections, the main switch

must be at “OFF”.

4-3. Connecting the Loads

Calculate the total power consumption of the output load. Make

sure that the total power consumption does not exceed the rated

power.
