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. 

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.

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)
Peak current can be supplied at a heat sink temperature of <75 °C (BM5X43) and <80 °C (BM5X44), only.
If these heat sink temperature thresholds are exceeded, the output curre
nt is automatically derated to the rated current.
10)
For cooling versions S and A, only.
11)
The sum of the transmitted mean effective power via the DC link terminals and the mean effective power at the motor terminals, may
not exceed the specified value continuously.
12)
The motor connection of the device provides a limited short-circuit protection.
13)
At a hardware status of < 4006 or if UL508C is complied with: at maximum 4 A
