Section 3 Technical Data and Performance

Overvoltage Categories

Equipment permanently
connected to low voltage
mains
Equipment not energized
directly from the low voltage
mains
AC mains power supplies are compliant with Overvoltage Category III networks
(industrial mains). All I/O signals are overvoltage II compliant.

Equipment Class and Insulation Voltages

Equipment Class

The S800 equipment class is Class 1 according to IEC 60536. Class 1 means
protection of electric shock by protective earth connection (PE). In this case this
means a PE- connection must be made to the DIN-rail.

Insulation Voltage

All accessible ports on S800 modules are galvanically isolated from ground and
system. For actual module isolation configuration, consult module data sheets.
