Memory card

Functionality
A memory card can be used on the Parameter Loader and allows you to upload/download
parameter sets to/from the converter. For detailed use of the memory card, refer to Appendix
"Parameter Loader (Page 357)".

RS485 termination resistor

An RS485 termination resistor is used to terminate the bus for the RS485 communication
between the SINAMICS V20 and SIEMENS PLCs. For detailed use of the termination
resistor, refer to Section "Communicating with the PLC (Page 175)".

Residual current circuit breaker (RCCB)

Note
The SINAMICS V20 converter has been designed to be protected by fuses; however, as the
converter can cause a DC current in the protective earthing conductor, if a Residual Current
Circuit Breaker (RCCB) is to be used upstream in the supply, observe the following:
• SINAMICS V20 single phase AC 230 V converters (filtered) FSAC and FSAD can be
operated only on a type A 100 mA or type B(k) 300 mA RCCB.
• All SINAMICS V20 three phase AC 400 V converters (filtered or unfiltered) can be
operated on a type B(k) 300 mA RCCB.
• SINAMICS V20 three phase AC 400 V converters (unfiltered) FSA to FSD and FSA
(filtered) can be operated on a type B(k) 30 mA RCCB.
• When multiple converters are in use, one converter must be operated on one RCCB of
the corresponding type; otherwise, overcurrent trips will occur.
To use a type A RCCB, the regulations in this FAQ must be followed: Siemens Web site
