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
Figure 2-1 are not exceeded. If not stated otherwise, the
temperatures should be measured by placing a sensor exactly at the given locations.
Exact locations of critical temperature spots:
1. On the PIM (U34) (On top of the transformer). Maximum up to 90 o C.
2. On the 48V/12V DC/DC (U35) (on the PCB, next to the transformer). Maximum up to
125
o
C.
