  • Page 14: Rs-485 Electrical Connection With Modbus Network

    Communication System Manual UPS System: HIPULSE E (Modbus/Jbus Interface) Electrical installation 3.1.1 RS-485 electrical connection with Modbus network There is a male 3-way X4 connector for connection with the Modbus network (BMS) on the bottom of the board. To make the connection, connect a two-wire shielded cable (supplied by others) to the X4 terminal board of the Operator Logic Board, unless a multipoint connection is required (described in the following paragraph).

  • Page 15: Multipoint Rs-485 Connection

    UPS System: HIPULSE E Communication System Manual Electrical installation (Modbus/Jbus Interface) 3.1.2 Multipoint RS-485 connection To obtain a multipoint RS-485 serial line connection composed of 1 to 32 UPSs, all the devices connected with the Modbus network must be connected with one another in parallel. In this case, in addition to the connection of the Operator Logic X4 with the Modbus network described above, X5 must be used for an additional connection with a cable to provide output to the logic of the other units (refer to Figure 3-6).
