4.10 Permissible line system conguration as a function of the
installation altitude
Description
From an installation altitude of 2000m above sea level and higher, the following constraints
apply to the line system conguration.
Converter input voltage Permissible line system conguration for installation altitudes
2000mto4000m above sea level
3 AC200V…240V +10%‑20% Connection to a TN or TT system with upstream isolation trans‐
former
Connection to an IT system with upstream isolating transformer
with the secondary side grounded at the neutral point
3 AC380V…415V +10%‑20%
3 AC440V…500V +10%‑20%
Connection to an IT system with upstream isolating transformer
with the secondary side grounded at the neutral point
Alternative for TN or TT system:
• Line supply with grounded neutral point
• Connection with upstream isolating transformer with the sec‐
ondary side grounded at the neutral point
