The connector for the power supply is specified for 8A and can accept wire cross-sections up to 1.5 mm2
with ferrules without collars. When using ferrules with collars, the wire cross-section is reduced to 1mm2.
Use 1.5mm2 or 1mm2 for long supply lines to achieve a low voltage drop on the supply lines. At least 22V
should be present at the power supply plug of the transmitter box so that the transmitter box remains
switched on in the event of voltage fluctuations. The plug is included in the scope of delivery. You can obtain
a replacement plug from your Beckhoff Sales using the following ordering option:
• C9900-P944: Power supply connector for CU8xxx, 3-pin connector with spring-cage connection for the

4.2 Control cabinet installation
NOTICE
Extreme environmental conditions
Extreme environmental conditions can cause damage to the transmitter box.
• Avoid extreme environmental conditions.
• Protect the transmitter box from moisture and heat.
NOTICE
Incorrect installation
Mounting the device in a way that deviates from the documentation can impair its functionality.
• Mount the device only in the orientations shown in the documents.
The CU8803-000x transmitter box is designed for DIN rail mounting in control cabinets of machine and
system engineering. Please observe the environmental conditions prescribed for the operation (see Chapter
8 Technical data [}21]).
The following dimensions of the device are given in mm.

4.3 Connect transmitter box
CAUTION
Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, observe the following:
• Never connect or disconnect the transmitter box cable during a thunderstorm.
• Provide protective earthing for handling the transmitter box.
NOTICE
Incorrect connection procedure
Incorrect procedure when connecting the cable can cause hardware damage.
• Follow the documented procedure for connecting the cable.
• First connect the cable and only then switch on the power supply.
To make the transmitter box ready for operation, you have to connect it. The first step is to ground the
device. Then you can connect the cables and the power supply.
An external power supply unit is required to supply 24VDC (-15%/+20%) for operating the device.
The cabling of the transmitter box in the control cabinet must be done in accordance with the standard EN
60204-1:2006 PELV = Protective Extra Low Voltage:
• The PE conductor (protective earth) and the "0V" conductor of the voltage source must be on the
same potential (connected in the control cabinet).
• Standard EN60204-1:2006, section 6.4.1:b stipulates that one side of the circuit, or a point of the
energy source for this circuit must be connected to the protective conductor system.
Devices connected to the transmitter box with their own power supply must have the same potential for the
PE "0V" conductors as the control panel (no potential difference).
Grounding
Potential differences are minimized and electrical currents are diverted to the ground through protective
earthing or potential equalization of electronic devices. This is to prevent dangerous touch voltages and
electromagnetic interference.
The voltage socket of the transmitter box contains a PIN for protective earthing. Establish the low-resistance
protective earthing by connecting the power supply.

Commissioning
CU8803-000x 17Version: 2.0
Connect transmitter box
Make sure that you plug all data transmission cables into the transmitter box first and then connect the
power supply.
Cables with a maximum cable cross-section of 1.5 mm2 can be used for connecting the power supply. For
long supply lines, use 1.5 mm2 cables to achieve a low voltage drop on the supply line. At least 22V should
be present at the power supply plug of the transmitter box so that the transmitter box remains switched on in
the event of voltage fluctuations.
Proceed as follows to connect the 24VDC power supply unit:
1. Plug the voltage connector into the voltage socket on the transmitter box.
2. Screw the voltage connector to the voltage socket.
3. Connect the transmitter box to your external 24V power supply.
4. Switch on the 24V power supply.
5. Measure the voltage at the 3-pin connection strip of the transmitter box.
ðYou have connected the transmitter box.
Mounting strain relief
To meet the criteria of ATEX certification II 3G Ex ec IIC T4 Gc and II 3D Ex tc IIIC T135°C Dc for use in
hazardous areas, you need a strain relief for the USB connector. Use the Beckhoff ordering option C9900-
Z484 for this.
The strain relief is labeled on one side. You can see from the labeling which of the two brackets is to be used
for the CU8803 transmitter box. The corresponding bracket is additionally marked in Figure 10.
To mount the strain relief on the DIN rail next to the transmitter box, follow the steps below, shown in Figure
10:
1. Hook the strain relief bracket into the DIN rail with the lower hook immediately to the right of the
transmitter box (section A). Make sure that the labeled side faces to the right.
2. Tilt the strain relief into a straight position to hook the other side of the bracket into the DIN rail (section
B).
3. Tighten the two Torx TX20 screws on the strain relief bracket (section C).

2. Unscrew the 3-pin voltage connector and pull it out of the voltage socket.
3. Remove the power supply cable if the 3-pin connector is to remain with the transmitter box.
4. Make a note of the wiring of all data transmission cables if you want to restore the cabling with another
device.
5. Cut the cable ties on the strain relief on the optional C9900-Z484 strain relief, if present.
6. Disconnect all data transfer cables from the transmitter box.
ðYou have disconnected the cables and power supply.
DIN rail disassembly
First, remove the optional strain relief, if present, from the DIN rail by following the steps shown in Figure 11:
1. Loosen and remove the two Torx TX20 screws (section A). Make sure that the strain relief is secured
against falling down.
2. Unhook the upper hook of the bracket from the DIN rail (section B).
