Thereshould be no additional control components(contactors or relays) inside the SAMI GSand no control cables other than those of theSAMI GS.The control connections of the SAMI GS aregalvanically isolated from mains potentialand have a 10 MΩ resistance from theinverter frame i.e. PE. Because of this, thereis no need to connect X50/2,4,6 and 8 (logicGND) to TE or PE. However, it could proveuseful to do this if EMC problems occur.Analogue input and output signals:A separate twisted pair must always be usedfor each individual signal.Digital inputs:It is strongly recommended to use screenedcables for digital inputs (DI).
