When connecting the operation panel using a connection cable
When connecting the operation panel (FR-DU07) to the inverter using a cable, the operation panel can be mounted
on the enclosure surface and operationality improves.
Do not connect the PU connector to the computer's LAN port, FAX modem socket or telephone connector.
The inverter and machine could be damaged due to differences in electrical specifications.
⋅ Refer to page 5 for removal method of the operation panel.
⋅ When using a commercially available connector and cable as a parameter unit connection cable, refer to
⋅ The inverter can be connected to the computer and FR-PU04/FR-PU07.
