Terminal 68 is connected to the P signal (TX+, RX+), whileterminal 69 is connected to the N signal (TX-,RX-).Always use parallel connections for the Low harmonic Drive to ensure thatboth filter and drive part is connected..Illustration 5.4: Connection example.In order to avoid potential equalizing currents in the screen, earth the cable screen via terminal 61, which is connected to the frame via an RC-link.Bus terminationThe RS-485 bus must be terminated by a resistor network at both ends. If the drive is the first or the last device in the RS-485 loop, set the switch S801on the control card for ON.For more information, see the paragraphSwitches S201, S202, and S801.VLT AQUA Low Harmonic Drive Operating In-structions 5 How to Operate the Low Harmonic DriveMG.20.T1.02 - VLT® is a registered Danfoss trademark 775
