Inverter grounding terminals Grounds inverter chassis (casing).
Connected with earth.
(1) Main circuit power input terminals (L1/R, L2/S, and L3/T)
1) The main circuit power input terminals, L1/R, L2/S, and L3/T should be connected with the power source
via earth-leakage circuit breaker for line protection. Any phase may be connected to any lead. If the
zero-phase current is detectable by the upstream system, however, ordinary circuit breakers may be
used.
2) Connect a magnetic contactor so that the inverter can be disconnected from the power source to minimize
the influence of any failure when the inverter protective function is activated.
3) Do not start or stop the inverter by turning the main power switch on or off. Use the control circuit
terminals, FWD and REV, or the FWD, REV, and STOP keys on the KEYPAD panel to start or stop the
inverter. When the inverter is inevitably started or stopped using the main power switch, do not turn it on
or off more than once per hour.
4) Do not connect any terminal to a single-phase power source.
