that appropriate radio frequency emissions compliance is maintained.
Operation
Blade Damage
High humidity and condensation on the blade surface causes short circuits.
Do not operate the blade outside the specified environmental limits. Make sure the blade is
completely dry and there is no moisture on any surface before applying power.
Do not operate the blade below -5°C.
Overheating and Blade Damage
Operating the blade without forced air cooling may lead to overheating and thus damage of
the blade.
When operating the blade, make sure that forced air cooling is available in the shelf.
Injuries or Short Circuits
Blade or power supply
In case the ORing diodes of the blade fail, the blade may trigger a short circuit between input
line A and input line B so that 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 more voltage on the line that has
been disconnected before continuing your work.
