The signal is looped through all units. Two «RS 485+» terminals and two «RS 485-» terminals are located on each terminal block. This means that the signal can be led into the solar inverter at one terminal and out of the solar inverter at the other termi- nal. The RS 485 signal is led out of the last solar inverter in the series into the interface converter using the following configuration: «RS 485+» to «DATA+» and «RS 485-» to «DATA-».

The interface converter generates an

RS 232 signal. It is connected to the PC with the standard modem cable type D. Jumper JP400 must be closed at the solar inverter that is furthest away from the interface converter. For all other solar inverters it must be open. An address must be alloca- ted, to enable identification of the indivi- dual solar inverters. This is described in Chapter 2.3 Commissioning, under «Configuration».
