2.3. ISOLATION
Converter ADA-4040A has 2-way or 3-way galvanic isolation on the levels 1kV= or 3kV=, depend on version described in section
VERSIONS.

3. INSTALLATION
This chapter will show you how to use and connect ADA-4040A to RS485, RS422 network and power supply.
In the purpose of minimization of disruptions from environment is being recommended to:
- apply multipair type shielded cables, which shield can be connected to the earthing on one end of the cable,
- arrange signal cables in the distance not shorter than 25 cm from powering cables.
- apply cable of adequate cross-section due to voltage drops for converter powering,
- use suppression filters for powering converters that are installed within a single object.
- not supply converter from power circuit device that generates large impulse interference such as transmitters, contactors.
3.1. ASSEMBLING
The cover of ADA-4040A converter is adapted to assembly on TS-35 (DIN35) rail. To install converter you should mount device on the
rail upper part of the cover then press bottom part to hear characteristic „Click” sound.
3.2. COMPUTER CONNECTION
To connect ADA-4040A converter via the RS1 port to computer equipped with RS-232 or USB interface, is needed additional
converter e.g. ADA-I1040 RS232 to RS485/RS422 converter or ADA-I9140 USB to RS485/RS422 converter (or other), which is
connected to RS2 port of ADA-4040A.
The ways of connections of ADA-4040A to PC are shown below.
