Penguin Edge™ RTM-ATCA-F140 Safety Notes Summary (6806800P10F) 9
Injuries or Short Circuits - Blade or Power Supply
In case the OR-ing diodes of the blade fail, the blade may trigger a short circuit between
input line A and input line B so that input line A remains powered even if it is disconnected
from the power supply circuit (and vice versa).
To avoid damage or injuries, always check that there is no voltage on the line that has been
disconnected before continuing your work.
The EMI radiation compliancy of the product has been qualified in a reference system.
Please note that the integrator needs to verify the EMI radiation compliancy of other
configurations/settings.
