11.3.2 Derating (Location-Dependent)
Depending on the installation altitude and the surrounding air temperature, it may be nec-
essary to reduce the load.

11.4 Parallel Connection
In parallel operation, set the output voltage of the products that will be connected in paral-
lel to precisely the same value, if possible. The resistance of the conductors between the
power supply units and the load must be nearly identical. Only connect products of the
same type in parallel.
