3 Safety notes 3 Safety notes CAUTION General safety regulations Please comply with the following general regulations during engineering and execution: ● Measures/prohibitions to prevent the hazard of electrical and mains power ordinances for the given country. ● Other applicable, national regulations. ● Building installation regulations for the given country. ● Regulations of the utility company.
Safety notes 3 CAUTION NEC (North America) Use of class 2 transformers limited to 100 VA or class 2 circuits at max. 100 VA by a non-limited transformer of max. 400 VA, combined with overcurrent protection (T 4 A fused) for each AC 24 V device. Multiple fuses for multiple insulated secondary circuits per transformer are possible (see Power requirements [➙ 22]). The same applies to DC 24 V power supplies.
3 Safety notes CAUTION Transformer specification AC 24 V IEC: Use safety insulating transformers as per IEC 61558 with double insulation designed for 100% duty to supply SELV or PELV circuits. USA: Class 2 circuits per UL 5085-3 Power taken from the transformer should be at least 50% of nominal load for efficiency reasons (effectiveness). Transformer nominal power should be at least 25 VA. For smaller transformers, the ratio of open circuit voltage to full load is unfavorable (> + 20 %).
Safety notes 3 CAUTION Caution with regard to foreign voltages Any insertion or drawing of dangerous voltages to the system's low-voltage circuit, e.g. caused by improper wiring, directly places people at risk and may result in the partial or complete destruction of the building automation and control system.

5 System limits Limits for MS/TP 5.4 Limits for MS/TP Use the router PXG3.L / PXG3.M with HW Index C only. Data point integration: MS/TP devices are considerably slower than IP devices due to the lower network speed. Reference value: Approximately 15 times slower (depending on the project setup). MS/TP is tested with 10 devices that support COV (e.g. DXR2). Recommendation: Assign or integrate a maximum of 10 MS/TP devices on one network branch.

7 Planning (hardware) IT security 7 Planning (hardware) 7.1 IT security Desigo Control Point works with devices with a web interface. Technically, this would allow to remote connect to their web interface also by the Internet. For security reasons, this is not allowed directly. If a remote access is required, it mandatorily must be secured by dedicated additional network IT-security means. As a consequence, you must comply with all IT security rules.
Planning (hardware) Topologies 7 7.3 Topologies Various viewpoints can guide planning operating and monitoring concepts: ● Who operates which parts of the plant? ● What devices are used? ● How large is the system? ● How is the building subdivided (floors, tenants, etc.)? Use case: Small project Project requirements: ● Small heating and ventilation plants ● Web access for remote operation ● Local operator unit Example: Standard Web Browser PXM50.E PXM40.E PXM30.
Planning (hardware) 7 Power requirements Use case: Project without touch panels Project requirements: ● Multiple heating plants and/or air handling units ● Some rooms have room automation ● Web access for remote operation Example: Standard Web Browser BACnet/IP PXG3.W100-1 PXG3.W200-1 BACnet devices 7.4 Power requirements 7.4.1 Power consumption per device Type PXM30-1 AC 24 V ± 20 % DC 24 V ± 15% PoE (DC 48 V Class 4) Max. 29 VA Max. 17 W n.a.

Planning (hardware) 7 Power requirements 7.4.2 Transformer sizing AC 24 V The transformer power is the sum of the power consumption of the connected devices. Operating voltage The operating voltage is AC 24 V. It must meet the requirements for SELV or PELV per IEC 60364-4-41. NEC: Class 2 transformers or class 2 circuits. Permissible deviation to nominal voltage AC 24 V on the Transformer: +20%/-10%. This guarantees a tolerance of +/- 20% on the devices after considering line and contact resistance.
Planning (hardware) 7 Power requirements 7.4.3 Power requirements for DC 24 V Operating voltage The operating voltage is DC 24 V. It must meet the requirements for SELV or PELV per IEC 60364-4-41. NEC: Class 2 circuits. Permissible deviation to nominal voltage DC 24 V on the power supply: +15% / -10%. This guarantees a tolerance of +15/-15% on the devices after considering line and contact resistance (web server: -20%).
Planning (hardware) 7 Ethernet 7.5 Ethernet For detailed information on Ethernet, see: ● Ethernet, TCP/IP, MS/TP and BACnet fundamentals (CM110666) ● Practical guide on IP networks in building automation and control (CM110668) ● Practical guide on BACnet networks in building automation and control (A6V11159798) ● Desigo building automation and control - Technical principles (CM110664) ● IT security on installations with Desigo (CM110663) The following provides only specific notes on topology.
Planning (hardware) 7 Ethernet 7.5.1 Cable Desigo Control Point devices are connected over switches and Ethernet cable with RJ45 plugs. The following conditions must be met: Bus cable and length: ● Standard Ethernet cable: Min. category 5 ● Shielded or unshielded ● STP (Shielded Twisted Pair) or UTP (Unshielded Twisted Pair) ● Length between switch and room automation station: max. 100 m ● Length between room automation stations: Max. 100 m ● Number of devices on a line topology: Max.
Planning (hardware) Ethernet 7 PoE topologies PoE requires a star topology. Typical PoE switches have 4 to 16 outputs. As a result, multiple switches are used in a line topology on larger systems (e.g. suites in a hotel). Additional topologies: ● Certain switches (general industrial types) possess an uplink, i.e. multiple switches can be switched in series. ● An individual consumer can be powered using a PoE injector.
