Please pay attention to the capacity of the output terminals. The terminals are used according to the
different settings for P.40 and P.85 (output terminal function selection).When the output terminal
function selects 10, connect the relay driving the commercial power-supply operation. When the
output terminal function selects 9, connect the relay driving the inverter operation. When the external
input terminal function selects 37, switch the inverter to commercial power-supply operation. When
the external input terminal function selects 38, manually switch the signal CS.
Warning:
1. MC1 and MC2 must be mechanically interlocked; the running direction of the inverter
operation and the commercial power supply operation should be consistent.
2. Use the commercial power operation switchover function under the external operation mode.
3. STF/STR is effective when the CS signal is ON.
Here are some typical sequence diagrams for the switchover of the commercial power supply
frequency:
