Technical Notes:
- e jumper X40 must be removed.
- e communication BUS between the devices of the
simple cascade is via Modbus protocol (RS485).
- e Modbus parameters, which can be congured
via "MENU", have no eect on the simple cascade
but serve for the BMS.
- In one pair of the twisted pair, connect the 'Data +'
and 'Data -' signals, and in the other pair, connect
the 'GND'.
- e jumper between "TRD" and "T-"terminals is set
up by the Installer (the 120ohm electric resistance is
already on the generator).
