Characteristic curves
SINAMICS G120 standard inverters
0.37 kW to 250 kW (0.5 hp to 400 hp)
Power Modules
Derating data, PM240-2 Power Modules
(continued)
Ambient temperature
Low overload (LO) for PM240-2 Power Modules
High overload (HO) for PM240-2 Power Modules
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.
Installation altitude
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
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.

Pulse frequency
1)
The pulse frequency can only be switched over from 4 kHz (default) to
2 kHz for the low overload (LO) duty cycle.
