4.2 Electrical installation

4.2.1 General considerations

Installation is normally treated as category CAT III (IEC 664), which in principle means permanent connection to a 230 V AC mains supply. For the Xenta 400, this is only applicable to the relay outputs of the I/ O modules.

All equipment connected to the TAC Xenta units must comply with the following standards:

-EN 60 742 (or other relevant safety standard; for example ETL listing UL 3111-1, first version and CAN/CSA C22.2 No. 1010.1-92)

for the device(s) that provide an ELV-type power supply (normally 24 V AC) to the controller and other connected equipment.

-EN 61 010 or IEC 950 (or other relevant safety standard)

for computers, modems and other equipment powered by a 230 V mains supply.

If equipment using a 230 V mains supply is connected to a relay output terminal of the I/O modules, low-voltage equipment connected to the other relay terminals of the controller must provide at least basic insulation to all touchable parts.

We strongly recommend that switches are installed to make it possible to separate external equipment when the relay output terminals control equipment using a 230 V mains supply.

4.2.2Terminals and units

•Mount the terminal part on a DIN rail.

•Connect the cables to the correct terminals, see the figure below.

•Put the electronics part of the module on the terminal part.
