Internal Wiring for Modular Inverters S75 - S80
Modular inverters S75 and S80 use both parallel-connected inverter modules and power supply modules.
To obtain parallel-connection, inverter modules equipped with splitter boards are required.
The following links are required:
N. 2 power connections with 60*10mm copper bar between the power supply units and the inverter modules
in order to deliver DC voltage.
N. 12 links with 9-pole shielded cable (S80) or N. 11 links with 9-pole shielded cable (S75) for the analog
measures.
Type of cable: shielded cable
N. of conductors: 9
Diameter of each conductor: AWG20÷24 (0.6÷0.22mm
2
)
Connectors: 9-pole SUB-D female connectors
Connections within the cable:
