Take note of safety instructions for Ex applications
Please note the Ex specic safety information which you can nd on our homepage www.vega.com/downloads under "Approvals" and which
comes with every instrument. In hazardous areas you should take note of the corresponding regulations, conformity and type approval certi-
cates of the sensors and power supply units. The sensors must only be operated on intrinsically safe circuits. The permissible electrical values
are stated in the certicate.

1 Product description
Overvoltage arresters limit interference and overvoltages in industrial
system to uncritical values so that failures and malfunctions of connected
instruments cannot occur.
An overvoltage arrester can be used on both sides of the circuit. It is e.g.
mounted on a carrier rail near the sensor, directly in the cable entry, or
near the signal conditioning instrument, PLC or control system. This way,
the eld side as well as the processing side are protected in case of volt-
age surges.
The following circuit diagram shows the electrical conguration of an
overvoltage arrester.
