    Data cable connection way

    The connection between each module is through the external data line. Please confirm the sequence of the two external data line ports before connecting each module. Each confluence

    acquisition module has two outside connection ports(Figure 4): Port I and Port II, in which Port I is used to connect upstream module and Port II is used to connect follow-up modules. Please pay attention to it that the propulsion part of the data line connector must be fixed with the groove on the port.

    The connection sequence order of PV confluence acquisition modules must follow: confluence acquisition module 1’s port Ⅱ-->confluence acquisition module 2’s port , Ⅰ confluence acquisition module 2’s port Ⅱ-->confluence acquisition module 3’s port . Ⅰ

    When connecting the confluence acquisition modules ,multiple confluence modules should be in sequence order, it is not allowed to insert any other function module between two sequenced confluence modules. Wrong connection will lead to abnormal operation of the device.

    LCD display module can be connected with Port II of confluence acquisition module, The LCD display module is not necessary to be connected in at ordinary time except when testing and checking.

    The address allocation of PV confluence acquisition module is automatically distributed by the power module(main module), The first confluence acquisition module connected to the power module will be distributed automatically with 1st to 8th channels, and the next confluence acquisition module connected to port II will be distributed automatically with 9th to 16th channels, the final confluence acquisition module is distributed automatically with 17th to 24th channel.


    Installation schematic

    Note: The arrow shows current direction. Wrong connection will lead to abnormal operation of the device.


    Definition of input port

    After the address of confluence acquisition module is distributed by the main module,the input channel address of first module is from 1st to 8th channel,the input channel address of second confluence acquisition module is from 9th to 16th channel,the input channel address of final confluence acquisition module is from 17th to 24th channel. The input channel definition of 1st to 8th channel of a single module is shown as Figure 3.


    Wiring mode

    Note: Power supply circuit and voltage measuring circuit must be installed with fuse with 3A rated current and rated voltage that is the highest working voltage in these circuits to ensure safety.
