Comments/measures
Overvoltage category II
Pollution degree 2
To maintain the safety characteristics of
extra-low voltage circuits, external con‐
nections to the analog circuits and the
24 V DC nominal power supplies must
be powered by approved sources that
fulfill the requirements according to the
various standards for SELV, PELV,
NEC Class 2, voltage limited or power
limited.
The ground connection for the DIN rail
serves as a functional ground for dissi‐
pating interference currents.
IP 20: Protection against contact with
standard probe
Protection against solid bodies with di‐
ameters in excess of 12.5 mm
No special protection against water
Between the chan‐
nels
Between the chan‐
nels and the back‐
plane bus
Between the chan‐
nels and the power
supply
See Product Information "Use of mod‐
ules in zone 2 hazardous areas"
(Product information

en/view/19692172)).
All shielded cables must be grounded at
both ends to comply with the require‐
ments for electromagnetic compatibility.
If the shielded cable is routed out of the
hazardous area for explosion-proof
equipment, both ends of the cable shield
must be connected to the potential
equalization.
