Connecting cables and power supply

Incorrect connection procedure
Incorrect procedure when connecting the cables and the power supply can cause hardware damage.
• Follow the documented procedure for connecting the cables and the power supply.
• Always connect the cables first and only then switch on the power supply.
• Please read the documentation for the external devices prior to connecting them.
Connection of incorrect battery packs
Connecting the wrong battery packs can cause damage to the device and the battery packs.
• Only connect the C9900-U330 Beckhoff battery pack.
The connections are located at the rear of the panel PC.
Connecting cables
Make sure that you first ground the PC (see chapter 4.3.2 Grounding the panel PC [} 29]) and then plug in all
data transmission cables.
Connecting the power supply
Cables with a maximum cable cross-section of 1.5 mm
long supply lines, use 1.5 mm
least 22 V at the voltage connector of the panel PC, so that the PC remains switched on during voltage
fluctuations.
Proceed as follows to connect the 24 V
1. First mount the power supply cable with the 8-pin connection strip without its strain relief housing.
2. Plug the voltage connector into the voltage socket on the panel PC.
3. Screw the voltage connector to the voltage socket.
4. Connect the PC to your external 24 V power supply.
5. Switch on the 24 V power supply.
6. Measure the voltage at the 8-pin connection strip of the PC.
7. Mount the strain relief housing on the 8-pin connection strip.
External battery pack
If you ordered your device with an integrated UPS, then you can connect an external battery pack and install
it on a DIN rail near to the PC. Use only Beckhoff battery packs for this:

You can use the UPS output of the power supply unit and connect a Beckhoff Control Panel as a second
display. If the supply voltage fails and the panel PC is only supplied by the battery pack, the control panel
remains in operation. Second display operators can use it to read the power failure notification, back up data,
and shut down the operating system.
