1)
All rated values refer to a DC link voltage of 540 V, a control voltage of 24 V and an environmental temperature of 40 °C.
2)
The output voltage is a pulsed DC voltage. The operating range refers to the RMS of the fundamental wave.

5)
At rated input supply voltage the device supplies the rated- / maximum output currents. At input voltages above the rated supply voltage
the output currents at constant output power have to be reduced, accordingly.

The input current must be reduced between 40 °C and 55 °C, refer to correction factors at changed operating conditions ZEnvironmen-
tal temperature– on page
55.
7)
The possible overload time at this moment is dependent of the device load and the heat sink temperature. The device load is determined
by the overload monitoring of the device.
8)
The specified value is only valid if there is no additional DC link capacitance connected to the DC link terminals. Refer to ZPower on

The sum of the transferred mean effective power via the DC link terminals and the transferred mean effective power via the motor ter-
minals may not exceed the specified va
