In case an outboard, EMC-compliant (optional) is used
1) Install the inverter and the filter on a grounded metal plate. Use a shielded cable also for
connection of the motor. Make the cables as short as possible. Connect the shield wire firmly to
the metal plate. Also connect the shield wire electrically to the grounding terminal of the motor.
2) Use shielded wire for connection around the control terminals of the inverter and also for
connection of the signal cable of an RS-485 Communications Card. As with the motor, clamp
the shield wire firmly to a grounded plate.
3) If noise from the inverter exceeds the permissible level, enclose the inverter and its peripherals
within a metal panel as shown in Figure 11.6.
