CAUTION
 The IP filtering function (Ethernet) (Pr.1442 to Pr.1448) is provided as a means to prevent
unauthorized access (with intentions such as to corrupt programs or data) by external systems, but
the function does not prevent it completely. In order to protect this product and the system against
unauthorized access from external sources, take security measures in addition to this function.
Mitsubishi Electric Corporation will not take any responsibility for any problems with the inverter
and the system incurred by unauthorized access.
The following are examples of measures to prevent unauthorized access.
- Install a firewall.
- Install a personal computer as a relay station, and control the relaying of transmission data using
an application program.
- Install an external device as a relay station to control access rights. (For the details of external
devices used to control access rights, contact the distributors of the external devices.)
