Figure 4: Permissible mounting positions
The mounting positions presented are permissible. To facilitate
mounting and maintenance, however, it is recommended that
you use position IMB 3.
For each mounting position, you should check the specified oil
level before commissioning, see
Filling volumes
on page 7.
Note
It is important that sufficient cooling air is supplied, sufficient
space is available for changing components and free access is
guaranteed to the electronic unit cover (PME120-AI).
To achieve this, allow for the following minimum distances:
