1)
The error „power supply not ready-to-operate“ is generated if the supply voltage falls below U
ACmin
for t > 0.1 s.
2)
Rated voltage is 400 V. 
With lower supply voltages the output power of the device is reduced. See correction factors, in case the operating conditions were
changed
ZSupply voltage– on page 57.
3)
The control voltage must accord to PELV (EN 61800-5-1, chapter 3.21) or SELV (EN 61800-5-1, chap. 3.35). 
At control voltage of < 24 V the ventilation power output is reduced. Therefore, it may be necessary, to reduce the output currents as
well.
4)
Required for UL 508C, only.
5)
Rate of change of the power supply frequency 1 Hz/s at a maximum (EN 61000-2-4, class 3).
6)
The connection and operation of a device with the identification BM4XXX-XTXX at an IT system or a grounded delta system, is not
permitted.
7)
Valid for BM444X/BM445X/BM446X/BM464X/BM465X/BM466X cooling versions S and A and BM 447X cooling version A.
