INVERTER INSTALLATION AND PRECAUTIONS
Main differences between the explosion-proof inverter and the standard inverter
NOTE
• For the details of each function, refer to the Instruction Manual (Detailed) of the FR-A800 inverter.
• When the Instruction Manual (Detailed) of the FR-A800 inverter is used for reference for the FR-B or FR-B3 inverter, replace the FR-A800 model (ND rated capacity)
with the FR-B/B3 model according to the following table.
