Fig. 4.7.2: ±48 VDC power supply and fan modules
4.7.3 ±24 VDC module
24 VDC modul shows the 24 VDC power supply and fan module. There is a 24 VDC cable
terminal in order to connect the supply voltage. It is important to take care of the right polarity of
the DC supply voltage. A fuse and a spare fuse are implemented inside the power supply and fan
module and can replaced if required. There is one LED informing about the status of the power
supply module. The power unit O.K. LED is lightening green provided that the power supply
module is working properly. The power supply and fan modules might be exchanged during
operation (hot plug-in technology) with neither harming the equipment nor having any impact on
the operation of the transmitter in case of a properly working backup power supply.

4.7.4 Fan-only module
For applications, where only one power supply is required, BKtel offers a fan-only module. Fig.
4.7.4 provides the view on the fan-only module.
The fan-only module can be exchanged during operation (hot plug-in technology) with having
neither harming to the equipment nor having any impact on the operation of the transmitter in
case of a properly working power supply.
