Pulse frequency
Ambient temperature
High overload (HO) and low overload (LO)
Note:
The PROFINET version can be butt-mounted at temperatures up
to 55 °C (131 °F). At temperatures between 55 °C (131 °F) and
60 °C (140 °F), side-by-side mounting is not possible.
Installation altitude
Permissible line supplies depending on 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
Note:
The connected motors, power elements and components must
be considered separately.
