13.1.3 When is a second AGG5.2 power transformer required?

The table shows examples of components groups that can be operated with just one
power transformer (including LMV5, AZL52, and PLL52):
Group SQM45

Diagram 2
Example:
Group 8
Diagram 1 = 3 x SQM45 + 1 x SQM48 + 1 x LMV5 + 1 x AZL52 + 1 x PLL52
can be operated with just one AGG5.2 power transformer.
If additional components are connected to this group (or to one of the other groups
listed in the table above), it will be necessary to divide the components into 2 groups
and to incorporate a second power transformer (as well as the respective external
fuses; refer to the corresponding note in the chapter Power supply for the
LMV5system).
The same requirements apply for the second group as for the first group with regard to
cable length and the maximum number of components.
Note:
2 SQM91 actuators can be operated on one second power transformer that is only
used to supply these actuators.
