IEC 60364-1.
Note
Above an installation altitude of 2000
m, you must observe the notes in Section Derating as
a function of the ambient temperature, pulse frequency, and installation altitude
(Page 37).
TN line system
In a TN system, a point of the generator or the transformer is grounded, normally the neutral
point. The housing of the consumer is also connected with the ground using this cable.
Neutral and protective conductors can be fed separately (N / PE) or together (PEN).
Figure 3-26 TN line system
● Power Modules without line filter can be operated on all TN line systems.
● Power Modules with integrated or external line filter can be operated only on TN line
systems with grounded neutral point.
