Basic insulation
ST
Safe isolation
(rated surge voltage of 4 kV)
A mixture of SELV and PELV is strictly prohibited. Only switch
230 V AC at one of the enable contacts if the adjacent contact
carries the same potential.
Safe isolation/reinforced insulation
(rated surge voltage of 6 kV)
Reinforced insulation (e.g., thanks to greater air clearances and
creepage distances between conductive paths) is designed for
one overvoltage category higher than basic insulation. This
means that SELV circuits of U ? 25 V AC or U ? 60 V DC and cir-
cuits with higher voltages can be mixed.
