4.3 Electrical installation

4.3.1 Wiring to a host

Stop!

An additional mains isolation is required, if

• a 820X or 821X controller is connected to a host and

• a safe mains isolation (double basic insulation) to VDE 0160 is necessary.

For this, it is, for instance, possible to use an interface module which provides an additional mains

isolation (see corresponding manufacturer’s data).

For wiring, the electrical isolation of the supply voltage must be taken into account.

Tip!

The communciation of controllers

820X and 821X may be interfered

by electromagnetic radiation. If

necessary, use an additional PE

shield cable .
