he devices are designed for wall-mounting (A). A conduit box is optional.
– Conduit box: Keep in mind the dimensions of the conduit box!
– Cable conduits on the wall: Keep a distance of 30 mm (from above) /

20 mm (from below) to the base plate (B), so that the device (C) c

napped onto the base plate.

s

• The base plate (B) has screw holes for all common flush-mount boxes.
The screw head height must not exceed 3 mm.

• The device (C) incorporates a KNX / PL-Link plug, a tool plug, and, depending
on the type, sensor element, keys, LCD panel, window for the label.
The cable can be pushed into channels on the rear.

• A KNX plug is enclosed with the devices

The optional metal-reinforced base plate QMX3.MP1 (B1) serves for two purposes:

• It is more rigid so that it does not bend when fixed in the middle with two screws
only (directly over a conduit box or a cavity wall box).

• It has a removable gray foam plate (B2) for mounting on a 68 mm diameter
cavity wall box. The plate compensates for the jutting edge of the box (s

unique KNX ID as alphanumeric and barcode display.

The addr

ess label can peeled off the device during mounting and stuck to a floor
plan or similar. The floor plan thus contains the assignment of KNX IDs and
physical installation location. This greatly simplifies the following steps. In addition,
the procedure serves as the basis for the recommended engineering and
commissioning process. If the adhesive labels are lost, all information is still
available in printed form on the housing.

1.6 Environmental compatibility, disposal

Note

1.6.1 General notes

This device was developed and manufactured with environmentally compatible
materials and procedures complying with all relevant environmental standards.

Note the following to dispose of the product following its useful life or in case of
replacement:

• Do not dispose of the device as part of standard household garbage, but as

special waste from plastic and steel, ferrite-magnet components.
This applies in particular to the PCB.

• For this reason, dispose of the components compatible with current

environmental, recycling, and disposal technologies.

Observe all local, applicable laws.

• The aim is to reuse as much of the basic materials as possible at the lowest

possible environmental impact. To this end, note any material and disposal
notes in individual components.

1.6.2 Environmental declaration

The product environmental declaration CM2E1602 contains data on
environmentally compatible product design and assessments (RoHS compliance,
materials composition, packaging, environmental benefit, disposal)

1.6.3 Notes on FCC rules

This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and
(2)this device must accept any interference received, including interference that
may cause undesired operation.

2.1 Notes on safety

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.

lease comply with the following general regulations during engineering and

P
execution:

• 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.

• Diagrams, cable lists, dispositions, specifications, and orders by the customer or

authorized engineering office.

• Third-party regulations, e.g. by the general contractor or building owner.

he electrical safety for building automation and control systems by Siemens is

T
essentially based on safely separating low voltage from mains voltage.

2.2 Device-specific regulations

Warning,

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.

Do not open the device.

The device is maintenance free. Only the manufacturer can repair the device.

2.3 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.

oth types of cables may be in the same cable duct, but in separat

• B
c

ompartments.

• If no three-sided, closed duct with separating wall is available, the interferi

ables must be separated by at least 150 mm from the others or placed i

c
s

eparate ducts.

• Crossings of strongly interfering cables with possibly susceptible entities must
be at a right angle.

• In exceptional cases, signal and interfering power cables may be run in parallel,
resulting in a high interference risk.

e recommend to generally 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
consideration of coupling to surrounding earth.
