    Chapter 1. Safety Precaution 1. Precautions of operation Before turning ON power CAUTION Choose appropriate power source with correct voltage setting as the input voltage specification of the inverter. WARNING Special care must be taken while wiring the primary circuitry panel. The L1 and L2 terminal must be connected to input power source and must not be mistakenly connected to T1, T2 or T3 terminal.
