Precautions for Correct Use
• For using the bypass mode, it is necessary to implement a interlock taking into consideration
the operation delay of the contactor when shifting to the commercial operation. •Make sure
that the system operation is safe in using the mode.
• The timing of the contactor control can be taken using the [EMBP] bypass mode signal (out-
put terminal: 076) as the contactor control signal. Take a interlock between the contactor on
the commercial power supply side and that on the inverter output side.
• Since the commercial circuit does not operate either when the earth leakage circuit breaker
(ELCB) trips, connect the commercial circuit of another system to MC2 if the backup is
required.
