Electrical installation

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 .
