Current derating as a function of the ambient temperature
Permissible output current as a function of the ambient temperature for
low overload (LO) and high overload (HO)
Note:
The operating temperature ranges of the Control Units should be
taken into account.
The temperature ranges are specified in the
section Technical specifications under Control Units.
Current derating as a function of the installation altitude
Permissible line supplies as a function of the installation altitude
•
Installation altitude up to 2000 m (6562 ft) above sea level
-
Connection to every supply system permitted for the inverter
•
Installation altitudes between 2000 m (6562 ft) and 4000 m
(13124 ft) 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
Permissible output current as a function of the installation altitude
Note:
The connected motors, power elements and components must
be considered separately.
Current derating as a function of the installation altitude and the ambient temperature
At installation altitudes above 1000 m (3281 ft), the permissible output current can be compensated to a certain extent using the
ambient temperature.
