4.3.3 Supply voltage
Danger of unnoticed damage to the internal electronics, due to
unacceptable overvoltages!
•
If an overvoltage of >36 V DC is inadvertently applied, the measuring
system must be checked in the factory. The measuring system is
permanently switched off for safety reasons, if the overvoltage is applied
for more than 200 ms.
The measuring system must be shut down immediately
When sending the measuring system to the factory, the reasons and
circumstances relating to the overvoltage must be specified
The power supply used must meet the requirements of SELV/PELV
(IEC 60364-4-41:2005)
