S-DIAS CPU UNIT CP 841 8 Assembly/Installation 8.1 Check Contents of Delivery Ensure that the contents of the delivery are complete and intact. See chapter 1.3 Contents of Delivery. INFORMATION On receipt and before initial use, check the device for damage. If the device is damaged, contact our customer service and do not install the device in your system.
S-DIAS CPU UNIT 8.3 Mounting Instructions The CP 841 is hung onto a DIN rail. The CP 841 can also be mounted in other positions using the optimal mounting angle. To mount the CPU unit, a DIN rail is required. The DIN rail must establish a conductive connection with the back wall of the control cabinet.
Page 33
S-DIAS CPU UNIT CP 841 WARNING It must be noted that the heat dissipated from the ventilation slots (depending on the ambient temperature) can reach up to 80 °C. Despite the low minimum clearances of the CPU unit, the greatest possible clearance between the heat sink of the CPU unit and the other objects in the control cabinet is recommended to ensure optimal cooling.
CP 841 S-DIAS CPU UNIT WARNING Burn hazard! At the maximum permissible ambient temperature, the outer temperature of the heat sink can reach 85 °C 8.3.1 Mounting Lift the snap-in hook of the first S-DIAS module. Hook the CP into the DIN rail from above.
S-DIAS CPU UNIT CP 841 8.3.2 Disassembly Lift the snap-in hook of the first S-DIAS module. Loosen the mounting screws of the CP. Then push the CP to the left away from the S-DIAS modules. Remove the CP from the DIN rail from below.

S-DIAS CPU UNIT CP 841 9 Wiring 9.1 Grounding The device must be grounded over a broad surface. This can be accomplished via the following measures: Installation in the control cabinet Ground connection Mounting holes etc. It is important to establish a low-Ohm earth connection to ensure fault-free operation. The ground connection must be made with the maximum cross section and largest (electrical) surface possible.
CP 841 S-DIAS CPU UNIT 9.2 Shielding For Ethernet, CAT5e (STP - Shielded Twisted Pair) cables are recommended. The cable shielding is connected to ground via the connector. Noise signals can then be prevented from reaching the electronics and affecting the function.
S-DIAS CPU UNIT CP 841 9.5 CAN Bus This section explains how to correctly configure the CAN bus. The following parameters must first be set: Station number and data transfer rate. 9.5.1 CAN Bus Station Number Each CAN bus station is assigned its own station number. With this station number, data can be exchanged with other stations connected to the bus.
It is recommended to avoid placing VARAN bus lines parallel to power cables whenever possible. SIGMATEK recommends the use of CAT5e industrial Ethernet bus cables. An S-FTP cable should be used for the shielding. An S-FTP bus is a symmetric, multi-wire cable with unshielded pairs. For the entire shielding, a combination of foil and braiding is used.
S-DIAS CPU UNIT CP 841 INFORMATION The VARAN cable must be secured at a maximum distance of 20 cm from the connector to protect against vibration! 9.6.1 Wiring from the Control Cabinet to an External VARAN Component If the Ethernet lines are connected from a VARAN component to a VARAN node located outside the control cabinet, the shielding should be placed at the entry point of the control cabinet housing.
CP 841 S-DIAS CPU UNIT 9.6.3 Shielding for Wiring Within the Control Cabinet Sources of strong electromagnetic noise located within the control cabinet (drives, transformers, etc.) can induce interference in a VARAN bus line. Spike voltages are dissipated over the metallic housing of a RJ45 connector. Noise is conducted through the control cabinet housing without further action from the electronic components.
S-DIAS CPU UNIT CP 841 9.6.4 Connecting Noise Generating Components With the connection of power components, which generate strong electromagnetic interference, it is also critical to ensure correct shielding. The shielding should be placed before a power element (or group of power elements).
CP 841 S-DIAS CPU UNIT 9.6.5 Shielding Between Two Control Cabinets If two control cabinets must be connected over a VARAN bus, it is recommended that the shielding be located at the entry points of both cabinets. Noise can be thereby prevented from reaching the electronics within the control cabinet.
S-DIAS CPU UNIT CP 841 10 Operation/Start-up 10.1 Configuration The device is configured using the SET and RESET buttons. SET button functional via later OS update. To enter the mode for setting changes, press and hold the SET button while the C-IPC is booting.
