Overvoltage and current protection
All voltage inputs are protected against voltage overload and current inputs against
currentoverload.Thisisspeciedforthehighvoltagechannelsat±2kVDC.
● Current inputs 2.5 A peak for all current ranges.
● Low voltage inputs 60 V peak for all ranges.
Exceeding these limits, particularly when connected to potentially high-current
sources, can cause severe damage that is not covered by the manufacturer's warranty.
Disconnect voltages before removing the card from the system.
The measuring circuit can carry hazardous voltages and should be disconnected
before the card is removed from the card slot of the measurement system.

For measurements falling within the scope of the EN 50110-1 and EN 50110-2, please
note that all cards with working voltages above 50 V AC RMS or 120 V DC may only
