7.5 Restrictions for special ambient conditions
PM250 Power Module
62 Hardware Installation Manual, 01/2016, A5E36265179B-AA
The Control Unit and operator panel can restrict the maximum permissible operating ambient
temperature of the Power Module.
Current derating or temperature reduction depending on the installation altitude
Above 1000 m above sea level you must reduce the inverter output current or the
permissible operating ambient temperature as a result of the lower cooling capability of the
air. Refer to the following diagrams for the values.
Permissible line supplies depending on the installation altitude
● Installation altitude up to 2000 m above sea level
– Connection to every supply system permitted for the inverter.
● Installation altitudes between 2000 m and 4000 m above sea level
– Connection to a TN system with grounded neutral point.
– TN systems with grounded line conductor are not permitted.
– The TN line system with grounded neutral point can also be supplied using an
isolation transformer.
– The phase-to-phase voltage does not have to be reduced.
