5-4
Converter
Equipment such as personal computers is not equipped with an RS-485 communications port but with an
RS-232C port, so an RS-485/RS-232C converter is required to connect them to the RS-485
communications card. It is recommended that insulated converters such as RS-485/RS-485 converters
(KS-485PTI by System Sacomm, Inc.) be used for eliminating electric noise.
Multi-drop branch connector
The RS-485 communications port of the communications card uses an RJ-45 connector. For multi-drop
connection of inverters, multi-drop branch connectors (MS8-BA-JJJ by SK Koki Co.) are required.
Cable
For the connection of the remote keypad, use an 8-wire straight cable with an RJ-45 connector. (Remote
keypad extension cable option: CB-5S)
For the connection of other equipment or connection of FRENIC-Mini inverters with each other, use a
cable that has signal wires only. (EIA568-compliant 10BASE-T)
- No converter is required for connection of the remote keypad.
- To connect the FVR-E11S series of general-purpose inverters to the FRENIC-Mini
series, take necessary measures for the difference of the pin assignment between
FVR-E11S and FRENIC-Mini series to avoid a short-circuited failure.
