During the safety qualification of this blade, the following on-board locations were identified
as critical with regards to the maximum temperature during blade operation. To guarantee
proper blade operation and to ensure safety, you have to make sure that the temperatures at
the locations specified in the following are not exceeded. If not stated otherwise, the
temperatures should be measured by placing a sensor exactly at the given locations. For your
convenience all temperature spots are shown in the figure below that provides a detailed view
of the blade.
