3.4 Connection diagram
The diagram below shows a basic connection example for running the inverter with terminal commands.
(Note 1) When connecting an optional DC reactor (DCR), remove the jumper bar from the terminals [P1] and [P (+)].
(Note 2) Install a recommended moulded-case circuit breaker (MCCB) or an earth-leakage circuit-breaker (ELCB) (with an
overcurrent protection function) in the primary circuit of the inverter to protect wiring. At this time, ensure that the circuit
breaker capacity is equivalent to or lower than the recommended capacity.
(Note 3) Install a magnetic contactor (MC) for each inverter to separate the inverter from the power supply, apart from the MCCB or
ELCB, when necessary.
Connect a surge killer in parallel when installing a coil such as the MC or solenoid near the inverter.
