2.2 Standard connections
Warning
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/-).
It could cause a fire.
See 6.13.4 for the connection of a resistor.
First shut off input power and wait at least 15 minutes before touching wires on equipment (MCCB) that
is connected to inverter power side.
Touching the wires before that time could result in electric shock.
Do not shut down the external power supply on ahead when VIA or VIB terminals are used as logic
input terminal by external power supply.
It could cause unexpected result as VIA or VIB terminals are 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.
Be Grounded
Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire when a malfunction or
current leak occurs.
