Correction factors if the operating conditions are changed
If the devices
BM5500, BM5600, BM5700
are operated at operating conditions, which
lead to different correction factors, then all correction factors must be considered by mul-
tiplying them simultaneously to achieve the output power and the output current.
The following correction factors are to be considered if nothing other is specified at the
„Technical data“ of the device:
3.3.5.1 Operating altitude
If the devices
BM5500, BM5600, BM5700
are operated above an absolute altitude of
1000 m, then the output power must be reduced against the rated power according to the
following curve.

NOTICE!
Devices BM551X, BM5526 and BM5527 have an operating altitude of maximum
2000 m.
NOTE!
Baumüller devices, which are provided for the operation at grounded delta systems
or IT supply systems, may have an operating altitude of 2000 m at these systems,
only. If the altitude is higher than 2000 m to 4000 m these devices must be operated
at TN systems and TT systems. Such systems, e. g. can be achieved by using an iso-
lating transformer with a secondary-sided star point.
