Overvoltage protection
NOTICE
Protection of the external power supply
If the optical reader is supplied via extensive supply lines or networks, interference by strong
electromagnetic pulses on the supply lines is possible, e.g. from lightning or the switching
of large loads.
The connection of the external power supply is not protected against strong
electromagnetic pulses. An external overvoltage protection module is required for this
purpose. The requirements according to EN 61000-4-5, Surge test on power supply lines,
are only met when a suitable protective element is used. A suitable device would be, for
example, the Dehn Blitzductor BVT AVD 24, article number 918 422, or a comparable
protective element.

Use in an area of plants with high-energy radiation
NOTICE
Protection of the image sensor from damaging radiation
When the SIMATIC MV500 optical reader is used in an environment of plants with high-
energy radiation, for example, laser light or arcs, the image sensor of the optical reader
must be protected from damaging radiation.
The image sensor is protected by means of suitable daylight filters:
• Radiation outside the visible light spectrum (IR and UV radiation) is filtered out.
• Visible light can pass without problem.
Danger of burns
NOTICE
Warning of hot surface
Electrical devices have hot surfaces. Do not touch these surfaces. Severe burns could be
caused.
Let the device cool down before you start work on the device.
