3. Mounting and installation
3.1 Safety information for mounting
− All work on the supply network and device must be
performed by qualified electricians.
− Observe the applicable laws and regulations of the country
in which the device is operated.
WARNING!
Risk of electric shock.
A failure to observe the ambient conditions can lead to
dangerous situations when working with current.
The device contains current-carrying parts. Contact with live
parts can lead to electric shock, burns or death.
• Power off the electrical system before installation.
• Secure the electrical system against being powered on again.
• Check that the device is powered off.
CAUTION!
Danger of damage due to incorrect
mounting.
An incorrect connection can destroy the device.
• Only mount the device in a faultless condition.
• Protect the device against moisture.
• Make sure that cables are not damaged, kinked or crushed.
• Observe the mains voltage (type plate).
• Make sure that the mains supply is suitable.
• Protect supply line with circuit breakers (F = max. 16 A).
• Use suitable fastening material.

When in operation, the device becomes warm as a small
proportion of the connected load is transformed into heat.
The nominal output of the device, as indicated, is designed for
D
flush-mounted installation in solid stone or concrete walls.
In the following cases, the maximum connected load must be
reduced by a minimum 20 %:
− With installation in a surface-mounted enclosure.
− With installation in a lightweight construction wall
(e.g. plasterboard on timber substructure, wood,
aerated concrete blocks).
− If heat sources are in close proximity to the device.
3.3 Installation
• Make sure the electrical system is powered off.
• Make sure the connected load corresponds with the
installation situation.
• Make sure the accessory box is in a suitable location.
• Loosen the nuts on the pressure switch.
• Connect the device in accordance with the circuit
diagram (A) or (B).
• Insert the device in the accessory box.
• Secure the device with screws or clamps.
• Fit the frame and cover of the switch program.
• Fasten the nuts on the pressure switch.
• Fit the dimmer knob.
• Switch on the electrical system.

3.4 Connection of LED retrofits
LED retrofits are LED lights that have been adapted to the
design of conventional lamps (e.g. incandescent bulbs).
LED retrofits from various manufacturers have differing pulse
current draws.
The device power is limited to 60 W.
When connecting multiple LED retrofits:
• Always use the same type and manufacturer.
• Set the basic brightness with the adjusting screw such that
flickering is prevented in the low dimming range.
• Check that the device is suitable for the number of LED
retrofits.
4. Operation
4.1 Check after commissioning:
Minimum brightness setting
The device is factory set for operation at 50 Hz. If the connected
load does not turn on, or flickers:
• Turn the pressure switch to adjust the load to the minimum
brightness (anticlockwise).
• Use a screwdriver to set the adjusting screw to the desired
90 100
basic brightness.
Temperature in °C
• Make sure that the connected load also lights up when set
to the lowest level of brightness.
4.2 Control
• Switching on / off: Press the pressure switch.
• Dimming: Turn the pressure switch. Turning the switch
clockwise increases the brightness.
5. Troubleshooting
Faults during operation
• Check circuit breaker and supply voltage.
• Check connected electrical loads and connection cables.
• Use a different lamp.
• Correct the basic brightness.
• Check micro-fuse and replace with an identical fuse if
necessary.
• If the internal thermal fuse blows: Replace device.
• With operation with LED loads: Connect anti-interference
capacitor (e.g. type X1, 330 nF) in the supply line between L
and N conductor.
Brightness changes with LED lamps
Mains voltage fluctuations are indicated by LED lamps with
changes in brightness. If brightness changes arise with direct
connection of the LED lamp:
• Do not use the dimming mode with the LED lamp.
Flickering
Ripples in the mains voltage are indicated by the light flickering
at low dimmer settings. This does not mean the device is faulty.
Humming
A humming sound can emanate from the device as a result of
operation. This does not mean the device is faulty.
If a fault cannot be remedied:
• Please contact your specialist dealer.
6. Disposal
The device contains electrical components and is subject to
the European directive 2012/19/EU for used electrical and
electronic equipment. The enclosure is made from recyclable
plastic.
• When the device reaches the end of its life, do not dispose
of it with normal household waste.
• Contact your town or district council to find out about
possibilities for the environmentally friendly reuse
(recycling) or appropriate disposal of the device.
• Dispose of the device in accordance with the
legal regulations, via a disposal company or at a
municipal waste disposal centre.
