Wiring Main Circuit Inputs

Installing Fuses
To protect the inverter, it is recommended to use semiconductor fuses like they are shown in the
table below.

Consider the following precautions for the main circuit power supply input.
•
If a moulded case circuit breaker is used for the power supply connection (R/L1, S/L2, and T/L3),
ensure that the circuit breaker is suitable for the Inverter.
•
If an earth leakage breaker is used, it should be able to detect all kinds of current should be used
in order to ensure a safe earth leakage current detection
•
A magnetic contactor or other switching device can be used at the inverter input. The inverter
should not be powered up more than once per hour.
•
The input phases (R/S/T) can be connected in any sequence.
•
If the Inverter is connected to a large-capacity power transformer (600 kW or more) or a phase
advancing capacitor is switched nearby, an excessive peak current could flow through the input
power circuit, causing an inverter damage. As a countermeasure install an optional AC Reactor
at the inverter input or a DC reactor at the DC reactor connection terminals.
•
Use a surge absorber or diode for inductive loads near the Inverter. Inductive loads include mag-
netic contactors, electromagnetic relays, solenoid valves, solenoids, and magnetic brakes.
