Max. ambient temperature, inverter
DSD considers the drive-specific reduction factors and an ambient temperature range of 0 ... 60 °C.
• The ranges from -20 ... 0 °C have to be checked manually.
• In a temperature range of 0 ... 40 °C, operation of the components can be carried out without a
power derating.
• For inverters the derating factor is stored in the DSD device-specifically.

Note!
• The DSD does not take sub-zero temperatures into consideration.
• For an ambient temperature < 0 °C you enter 0 °C.
• Make sure that the ambient conditions suit the motors. As a help, use the tables with
the correction values.
Note!
The upper and lower limit values can vary for the different inverters.
In the chapter "
the characteristics of the different inverter types are
listed.
