4.3 Connecting the push button extension
CAUTION
Risk of electric shock
Dangerous touch voltages can lead to electric shock. To avoid electric shock, adhere to the following point:
• Never connect or disconnect the device cables during a thunderstorm.
To prepare the push button extension for operation, you must connect it. The first step is to ground the
device. Then you can connect the cables and the power supply.
4.3.1 Grounding of the push button extension
Potential differences are minimized and electrical currents are diverted to the ground through grounding or
potential equalization of electronic devices. This is to prevent dangerous touch voltages and electromagnetic
interference.
EMC
NOTE
Hardware damage due to electromagnetic interference
Using the push button extension without functional earthing can lead to equipment damage due to electro-
magnetic interference.
• Only use the device with functional earthing.
Electromagnetic compatibility (EMC) refers to the ability of the push button extension not to interfere with
other devices and equipment through electromagnetic interference, and not to be disturbed by electrical or
electromagnetic effects.
For this purpose, the push button extension must comply with certain protection requirements. It has EMC
interference immunity according to EN 61000-6-2. The EMC interference emission of the device meets the
requirements of EN 61000-6-4.
The EMC of the device is improved by functional earthing. The functional earthing is established via the
mounting arm adapter during mounting on the mounting arm. This is ensured by the paint-free surface on the
mounting arm adapter. The mounting arm adapter is screwed to the mounting arm on this surface (1) (see
Fig. 11). In this way, the functional earthing is established starting from the mounting arm via the screw
connections on the push button extension.

C9900-M80020 Version: 1.3
4.3.2 Connecting cables and power supply
WARNING
Wrong power supply unit
Using the wrong power supply unit can lead to loss of safety.
• Only use a SELV/PELV power supply unit with a voltage limit of Umax= 36VDC on the output side.
NOTE
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.
NOTE
Unsuitable connection cables
Using unsuitable connection cables can cause damage to equipment.
• Only use suitable connection cables that are designed for the ambient conditions.
When you mount the push button extension to the C9900-M803 (2) or C9900-M804 (3) mounting arm, the
wiring runs through the mounting arms. At the foot of the mounting arms is the Harting HAN connection
socket with the Harting HAN plug. From there, the voltage cables and Ethernet cables are fed through the
mounting arms upwards to the opening (see Figure 12). Insert the plug connectors protruding from the
mounting arm into the push button extension.
