2.3. ISOLATION
Converter ADA-4010A 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 how to use and connect ADA-4010A to computer, 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-4010A converter is adapted to assembly on TS-35 (DIN35) rail. To install the converter, should be mounted on the
rail upper part of the cover then press bottom part to hear characteristic „Click” sound.
3.2. COMPUTER CONNECTION
ADA-4010A can be connected to RS232 port or USB of PC by the use of additional converter eg. RS232 to RS485 (ADA-I1040) or
USB to RS485 (ADA-I9140). The connection is made via RS485/RS422 bus, as on the figure bellow.
