Ambient temperature
Permissible output current as a function of ambient temperature for low
overload (LO) for PM240-2 Power Modules, frame sizes FSA to FSC
Permissible output current as a function of ambient temperature for low
overload (LO) for PM240-2 Power Modules, frame sizes FSD to FSF
Permissible output current as a function of ambient temperature for high
overload (HO) for PM240-2 Power Modules, frame sizes FSA to FSC
Permissible output current as a function of ambient temperature for high
overload (HO) for PM240-2 Power Modules, frame sizes FSD to FSF
Note:
The operating temperature ranges of the Control Units should be
taken into account.
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 and 4000 m (6562 ft
and 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.
Permissible output current as a function of the installation altitude for
PM240-2 Power Modules
System operating voltage
The rated output current remains constant over the 380 V to
480 V 3 AC voltage range.
