RS485 signals are floating and each signal is transmitted over a + line and a - line.

RS485 receiver compares the voltage difference between both lines, instead of the absolute voltage level on a signal line.

With RS485 there is no any common zero as a signal reference. Several volts difference in the ground level of the RS485 transmitter and receiver doesnot cause any problems.

11 Confidential


Even better EM noise resistance results are achieved if the + and - lines are twisted. Image below explains why.

When the cable is twisted, direction of the noise current is the oppositein different parts of the cable.

Because of this, the resulting noise current is many factors lower than with an ordinary straight cable.

RS485 communication lines: string inverters

RS485 line connection

Power-One inverters use a RS485 Half-Duplex communication line.

The cable used must be a screened twistedpair with a characteristic impedanceZ0=120Ohm.

Continuity along the communication linemust be given to the shielding and this lastmust be grounded at one end only.

•Connect all units of the RS485 chain in accordance with the “daisy-chain” scheme (“in-out”) respecting the correspondence between thesignals;•Activate, in the last element of the chain, the termination resistance ofthe communication line by switching the dedicated dip-switch;•Set a different RS485 address on each inverter for every inverter of thechain. NO INVERTERS SHOULD HAVE “Auto” AS AN ADDRESS;•The communication line should be no longer than 1000m in length;•Do not connect more than 64 inverters to the same RS485communication line.

ModBus devices (energy meters/LED displays/PLC)

- Inverter port (up to 64 inverters): monitoring extended

to 128 inverters

Communication port(s) with inverters

The new communication mode “Freeze and Hi-Speed” combines the

synchronization of data from the inverters with increased speed of data

acquisition from the inverters, allowing for a greater frequency in terms

of saving data in the internal memory and an accurate and efficient

system diagnostics.
