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)
Using the power choke listed in ZPower chokes– from page 288 at a power supply with U

= 0.4 %.
3)
The output voltage is a pulsed DC voltage. The operating range refers to the RMS of the fundamental wave.

Switching frequency of the inverter (adjustable).
5)
RMS at an environmental temperature of 40 °C.
6)
At rated power supply voltage the unit supplies rated / maximum output currents. With input voltages above the rated power supply
voltage the output currents must be reduced at constant output power.

7)
The input current must be reduced between 40 °C and 55 °C. Refer to correction factors at changed operating conditions ZEnviron-
mental temperature– on pag
e 55.
8)
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.
9)
For cooling versions S and A.
10)
UL508C is complied with: max. 4.0 A.
11)
Refer to ZMotor requirements– on page 52.
12)
With an output frequency lower than 0.5 Hz, the output current may be 80 % at maximum of the rated output current.
