User manual
*) Specialist knowledge required for the installation:
In particular, the following expertise is required for installation:
• the applicable “5 safety rules”: Switch off power; secure against switching back
on; determine voltage-free status; earthing and short-circuiting; cover or fence off
nearby live parts
• C
hoose appropriate tools, meters and, if necessary, personal protective equipment
• Evaluation of the measurement results
• Selection of the electrical installation material to ensure the shutdown conditions
• IP protection types
• Installation of the electrical installation material
• Type of mains supply network (TN system, IT system, TT system) and the con-
nection conditions that follow from them (classical earthing, protective earthing,
required additional measures, etc.)
If you do not have the expertise required for the installation, do not install it
yourself, but entrust the work to a qualied electrician.

b) Connection
• Item no. 1661882 and 1661883:
The construction of the product corresponds to protection class II (double or rein-
forced insulation). However, an internal connector for the protective earth conduc-
tor is provided. The product may thus be used for with protection class II and with
protection class I luminaires. A mains cable with protective earth conductor must
be used for luminaires of protection class I. The protective earth conductor of the
mains cable must be connected to the protective earth conductor of the connected
luminaire. Failure to observe this poses a danger to life from electric shock!
• Item no. 1661884 and 1661887:
The construction of the dimmer corresponds to protection class II (double or rein-
forced insulation). Only a luminaire of protection class II can be connected to the
dimmer. Do not connect luminaires to this dimmer that require a protective earth
conductor! There is a risk of a life-threatening electric shock!
• Item no. 1661885 and 1661886:
The construction of the dimmer corresponds to protection class II (double or rein-
forced insulation). Only luminaires with an operating voltage of 12 V/AC may be
connected to the dimmer.
• Make the connection only after ensuring the absence of any voltage/ current.
• Ensure that the insulation of the housing is neither damaged nor destroyed.
• The mains socket to which the product is connected must be easily accessible.
• Never overload the product. Note the maximum load capacity in the chapter “Tech-
nical data”.
• Observe the minimum load capacity in the chapter “Technical data”. Malfunction-
ing may occur if the minimum load capacity is not reached.
c) Operation
• The product is not a toy. Devices operated on mains voltage should not be used by
children. Therefore, be especially careful when children are around.
Use the product where it is out of the reach of children.
• Do not use the product in rooms with adverse environmental conditions, where
combustible gases, vapours or dust are or may be present! There is a danger of
explosion!
• Connecting to the mains voltage and operating the product is only permissible if
the housing is closed.
• Never use the product in a vehicle.
