Appendix G Conformity with Standards
Appendix-32
In case of EMC filter built-in type inverter
(1) Mount the inverter on a grounded panel or metal plate. Use shielded wires for the motor cable and route the
cable as short as possible. Firmly clamp the shields to the metal plate to ground them. Further, connect the
shielding layers electrically to the grounding terminal of the motor. Use a wiring guide, etc., and try as best as
possible to keep input wires and output wires separate from one another.
(2) For connection to inverter’s control terminals and for connection of the RS-485 communication signal cable,
use shielded wires. As with the motor connections, clamp the shields firmly to a grounded panel.
(3) If noise from the inverter exceeds the permissible level, enclose the inverter and its peripherals within a metal
panel as shown in Fig. G.1-3.
