Prohibited
Do not connect input power to the output (motor side) terminals (U/T1, V/T2, W/T3).
Connecting input power to the output could destroy the inverter or cause a fire.
Do not insert a braking resistor between DC terminals (between PA/+ and PC/- or PO and PC/-).
It could cause a fire.
First shut off input power and wait at least 15 minutes before touching terminals and wires on
equipment (MCCB) that is connected to inverter power side.
Touching the terminals and wires before that time could result in electric shock.
Do not shut down the external power supply on ahead when VIA terminal is used as logic input
terminal by external power supply.
It could cause unexpected result as VIA terminal is ON status.
Mandatory
action
Set a parameter f109 when VIA or VIB terminals are used as logic input terminal.
If it is not set, it could result in malfunction.
Set a parameter f147 when S3 terminal is used as PTC input terminal.
If it is not set, it could result in malfunction.
Be Grounded
Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire.
