4. Operation 4-1. Connection 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 17. 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.
Figure 18. Battery cabling 4-2. Connecting the input power Before making the DC input side connections ④, 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. If the total power consumption over the rated power of the inverter, remove the non-critical: loads until the total power consumption is below the rated power. 4-4.
