The RS485 link is a daisy-chained bus, without dropout lines. The RS485 link should also be terminated on both physical ends of the wire to reduce the noise on the network. Modbus network should be wired using Belden 9841 or equivalent. Belden 9841 is a single twisted shielded pair cable with a wave impedance of 120 ?. The network should be connected according to Figure 5 below. The connection of both the incoming and outgoing cables to the same terminal enables the disconnection of the module without disturbing the communication between other stations. 7 INSTALLATION Figure 5 RS485 wiring. The cable shield can be left unearthed. Signal C (common) is connected to ACS 140 chassis through 1 M? impedance. Table 1 RS485 connection terminals. Terminals X2 and X3 are connected in parallel.

See Chapter 3 – Programming. 5 Set up other drive parameters as needed. Refer to ACS140 Programming Guide and chapter 3 of this manual. 6 Disconnect power from the ACS140. 7 Set the operation mode of the adapter to RS232 with jumper S4. 8 Connect the adapter to the ACS 140. Connect the RS232 cable. Skip steps 2-6 if the default parameter setting of the ACS 140 can be used. Wiring RS232 bus is a point-to-point type bus. Typical usage is to connect the drive into the serial port of a PC. The maximum RS232 cable length is 3 metres. The RS232 cable is not included in the delivery parameter settings of the ACS 140 can be
