Blade Damage
Blade Surface
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.
Blade Overheating and Blade Damage
Operating the blade without forced air cooling may lead to blade overheating and
thus blade damage.
When operating the blade, make sure that forced air cooling is available in the shelf.
