3 Installation and connection
3.1 Preparation for installation
3.1.1 Select the mounting location
• Avoid direct sunlight exposure.
• Make sure that C6 E22 BM is properly (ergonomically) accessible to the operator.
• Choose a suitable mounting height.
• Ensure that the aeration holes are covered.
3.2 Checking the package contents
• Check the package content for visible signs of transport damage and for completeness.
• In the case of damaged parts, contact your KEB representative. Do not install parts that were damaged during the shipment.
3.3 Checking the operation conditions
• Read carefully the standards, approvals, EMC parameters and technical specifi cations for operation of the device. This information is available in the following sections:
- Certificates and approvals
- Electromagnetic compatibility
• Check the mechanical and climatic ambient conditions for operation of the device:
Ambient conditions.
• Follow the instructions for local use of the device: Notes about usage.
• Adhere to the permissible rated voltage and the associated tolerance range.
3.4 Mounting position
C6 E22 BM device is suitable for wall mounting.

3.4.1 Damage due to overheating
• All C6 E22 BM systems are designed for vertical mounting position.
• A inclined installation reduces the thermal convection by C6 E22 BM and the maximum permissible ambient temperature for operation. Please contact KEB for details. C6 E22 BM may otherwise be damaged and its certifications and warranty will be void.
• The ambient temperature must be between 0°C to +50°C measured 5 cm from all openings of the system where there is air entrance.
• Provide space around the system for air recirculation and heat exchange.
• Keep at least 7 cm of space behind (z) and to the sides (x) of the PC cell, while above (y) and below (y) the PC cell are needed 10cm.
• Make sure that the grids on PC cell for air exchange are free from objects and cables and far from other obstacles to the air flow.
• For example, when the system is installed in cabinets with no air-conditioning, it is necessary to ensure the exchange of air from outside through at least two openings:
• An opening should be placed under the PC cell, it must be large enough to allow the correct air flow from outside that is required to be within the limits specified in the section on temperature.
• A sufficient size opening must be positioned above the PC cell to allow the outflow of the hot air outside.
• It is possible to use one or more lateral openings instead of the two above mentioned, subject to the condition that their vertical dimension is long enough to ensure the heat required exchange.
• When the system is placed in air conditioned cabinets, the conditioning system must provide the air circulation with proper ventilation.
• When the system is installed in closed cabinets, it is still necessary to ensure that the maximum ambient temperature is +50°C.
• Mounting angle:
- The system is intended to be mounted vertically.
- For inclinations of more than 10° and up to 20° is necessary to decrease the maximum operating temperature of 5°C.
- For other installation modes contact KEB Automation KG.
For installation in control cabinets and, in particular, in closed containers, make sure the recommended ambient temperature is maintained.

3.6 Mounting the device
The system can be installed on a panel/wall as follows:
Tool required action
Cross screwdriver 2.5 mm Screw / unscrew 4 fixing screws
• Drill the required holes on the housing panel/wall according to the instructions detailed in paragraph 3.6 Dimensions.
• There are 4 fastening points. Fastening can be made using stainless steel screws
M4x20.

3.7 Grounding and bonding
Whenever two pieces of equipment connected to each other are far apart, it is possible that their ground connections could be at a different potential level. The data cable screens connecting the equipment’s chassis on one end and the C6 E22 BM chassis on the other end can therefore be subject to a high current circulation capable of destroying the interface. To overcome this hazard such current must be steered away from the interface. To achieve this goal the following methods can be used:
38
Figure 28: Power supply diagramm
1. Use an equipotential bonding cable (16mm 2 ) to connect the equipment ground to the C6 E22 BM ground.
2. Connect the data cable screens to the equipotential bonding rail on both sides before connecting the cable to the interfaces.
Insert the earthing eyelet terminal between the washers in the following sequence:

1 Nut
2 Spring washer
3 Plain washer
4 Eyelet terminal
5 Toothed washer

3.7.1 Power supply insolation
The C6 E22 BM power supply is galvanically isolated which means its output is electrically separated from its input. This feature has many benefits:
• Increases the noise immunity of the system.
• Avoids input short circuits in systems with the power supply grounded.
• Breaks ground loops which may cause interferences in the video signals.

The wiring diagram shows a simplified pictorial representation of the electrical circuit.
It shows the components of the circuit as simplified shapes, and the power and signal connections between the devices.

3.7.4 Power on
The system has to be connected to a 24 V (18-32V) power supply which satisfies the requirements of safe extra low voltage (SELV) in accordance with IEC/EN/DIN EN/
UL60950-1.
• Remove the two poles plug connector from the system (the system is shipped with the power plug connected).
• Always check that the voltage drop along the supply wiring is not excessive and the input voltage remains above the minimum required (18V) in the worst load condition.
• Connect the ground cables (PE) to the earthing points.
Figure 40: Screwdriver detail
• Connect the positive and the negative poles (also refer to the label on the back of the system) to their respective terminals of the two pole plug connector. Use wires with a cross-section of 1.5 mm 2 (AWG16).
Figure 41: Power on sequence
• The system begins bootstrap.
3.8 Shutdown
To shut down the system please follow the standard procedure of your operating system. After power down procedure is completed, the system will be put in a soft-off state, front side led will become yellow, and the user will be allowed to switch off power supply to the system. In this state the system will dissipate negligible power.
An ON/OFF switch is available on the system.
