3 Important information on safety and
disposal
This section explains general and system-specific regulations for mains and
operating voltages. It includes important information for your safety and the safety
of the entire plant.
3.1 General regulations
Comply with the following general regulations during engineering and execution:
●Electrical and mains power regulations for the given country.
●Other applicable, national regulations.
●Building installation regulations for the given country.
●Regulations of the utility company.
●Diagrams, cable lists, dispositions, specifications, and orders by the customer
or authorized engineering office.
●Third-party regulations, for example, by the general contractor or building
owner.
The electrical safety for building automation and control systems by Siemens is
essentially based on safely separating low voltage from mains voltage.
3.2 Device-specific regulations
Note permissible line lengths and topologies when planning and installing
controllers and field devices featuring KNX bus connection. Make sure the bus
supply complies with the KNX standard.
The device is maintenance free. Only the manufacturer can maintain the device.
3.3 Notes on EMC optimization
When setting up cable ducts, separate strongly interfering cables from susceptible
entities.
●Interfering cables: Motor cables especially from motors supplied by inverters,
energy-supplying cables.
●Susceptible entities: Control cables, low voltage cables, interface cables, LAN
cables, digital and analog signal cables.
●Both types of cables can be in the same cable duct, but in separate
compartments.
●If no three-sided, closed duct with separating wall is available, the interfering
cables must be separated by at least 150 mm from the others or placed in
separate ducts.
●Crossings of strongly interfering cables with possibly susceptible entities must
be at a right angle.
●In rare cases, signal and interfering power cables may be run in parallel,
resulting in a high interference risk.
It is recommended to use unscreened cables. Comply with the manufacturer's
installation recommendations for selecting unscreened cables. In general,
unshielded twisted pair cables have sufficient EMC properties for technical
building applications (including data applications) and do not require coupling to
surrounding earth.

3.4 Disposal
The device is considered an electronic device for disposal in
accordance with European Directive and may not be disposed of as
domestic waste.
●Use only designated channels for disposing the devices.
●Comply with all local and currently applicable laws and
regulations.

4 Mounting and installation
Comply with the following notes as well as the Mounting instructions
(A6V10733764) to mount the room operation unit.
4.1 Preparation
Check the package contents for visible signs of transport damage and for
completeness.
Do not install parts damaged during shipment. Contact your Siemens
representative in the event of damaged parts.
Note the information in the data sheet of these operating instructions before
installing the device:
●Climatic ambient conditions
●Protection classes
●The devices are suitable for wall mounting and panel mounting.
●Recommended height: 1.50 m above the floor.
●Do not mount the devices in recesses, shelves, behind curtains or doors, or
above or near heat sources.
●Avoid direct solar radiation and drafts.
●Seal the conduit box or the installation tube if any, as air currents can affect
sensor readings.
●Adhere to allowed ambient conditions.

4.2 Mounting instructions
●Mounting instructions A6V10733764 are enclosed with the devices.
●Remove the breakout on the housing before putting the cable into the gaining
channel.
●If 4-wire cables are used for daisy chain wiring, remove the cable coating, as it
will not fit in the gaining channel.
●Keep a distance of at least 20 mm from the base plate to any object above the
base plate such as cable ducts to snap the device cover onto the base plate.
