Requirements For Control Voltage / 24 V Power Supply; Control Voltage / 24 V Power Supply - Baumuller b maXX 5000 Series Instruction Handbook Manual

1)
In case of power supply failure ((0.9 - 0) x U
2)
The rated voltage is 400 V. At an power supply voltage of less than 400 V the output power of the device is reduced, refer to correction
values at changed operation conditions
3)
The control voltage must correspond to PELV (EN 61800-5-1, chapter 3.21) or SELV (EN 61800, chapter 3.35). With a control voltage
< 24 V the fan output is reduced. Thus, it could be necessary to reduce the output current. If UL 508C is being considered, the current
is limited to 4 A (with fuses, in accordance with UL 248) and to a voltage of max. 30 V
4)
Only necessary to comply with UL 508C, refer to
5)
Change speed of the mains frequency max. 1 Hz/s (EN 61000-2-4, Class 3)
6)
The connection and/or operation of a device with the identifier BM5XXX-XTXX on IT mains or grounded delta mains is not allowed.
7)
NOTE!
The distortion factor of the input current of following devices
BM50XX-XR /XS /XW ,, is at least twice as much the factor at operation with power choke.
The user has to check with the local power supplier whether an operation without power choke is allowed.

Requirements for control voltage / 24 V power supply

Figure 17:
The power supply unit for the 24 V voltage supplied must provide at least the rated output
that corresponds to the total 24 V power consumption of all devices of the rack system.
for t > 0.1 s), the error „Power unit not ready-to-operate" is generated.
