1 Safety instructions
Electrical devices may be mounted and connected only by electrically skilled
persons.
Serious injuries, fire or property damage are possible. Please read and follow the
manual fully.
Danger of electric shock. Device is not suitable for disconnection from supply
voltage.
Danger of electric shock. Always disconnect before carrying out work on the device
or load. In so doing, take all the circuit breakers into account, which support danger-
ous voltages to the device and or load.
This manual is an integral part of the product, and must remain with the customer.

5 Operation
Switching electronic operating devices on or off
￭ Press the control button.
Adjusting the brightness
Light is switched on.
￭ Turn the control button in the clockwise direction.
The light gets brighter up to maximum brightness.
￭ Turn the control button in the anti-clockwise direction.
Light gets darker to minimum brightness.
6 Information for electrically skilled persons
DANGER!
Electric shock when live parts are touched.
Electric shocks can be fatal.
Always disconnect before carrying out work on the device or load. For this, switch off
all the corresponding circuit breakers, secure against being switched on again, and
check that there is no voltage. Cover up adjacent live parts.

Connecting and fitting the device
Image2: Connection diagram - Potentiometer switches the lamp operating devices
directly
Image3: Connection diagram - Potentiometer and contactor for switching the lamp
operating devices
(1) Electronic potentiometer
(8) Lamp operating device with 1-10 V interface, electronic ballast
Control cable: appropriate type, cross-section and routing for the VDE specific-
ations for 250 V cables, control voltage has basic insulation. Control cable and
load cable may be routed in a common cable, e.g. NYM J 5 x 1.5.
Connect lamp operating devices and electronic ballasts with protective earth
conductor according to manufacturer specifications. The sum of the control
voltages must not exceed 50 mA; see manufacturer specifications for the lamp
operating devices.
Only use lamp operating devices and lamps that are of the same type, the
same power level, and from the same manufacturer. Otherwise there may be
differences in brightness between the individual lamps.

CAUTION!
Device defect when the 1-10 V interface is connected to mains voltage
Do not connect 1-10 V interface to mains voltage.
￭ Connect electronic potentiometer with switching function according to connec-
tion diagram (see figure 2) or (see figure 3).
￭ If multiple circuit breakers supply dangerous voltages to the device or load,
couple the circuit breakers or label them with a warning to ensure tripping.
￭ Fit device in appliance box; terminals must be at the bottom.
￭ Adjust basic brightness.
￭ Mount the frame and the central plate.
￭ Attach the control button.
7 Commissioning
Adjusting basic brightness
DANGER!
Electric shock when live parts are touched.
Electric shocks can be fatal.
Use only insulated tools to set the basic brightness! Cover up live parts in the work-
ing environment.
The basic brightness can be set by an electrically skilled person as required.
The device is connected as described above and fitted in an appliance box. The
frame, central plate and control button are not fitted.
￭ Switch on mains voltage.
￭ Press the rotary axle to switch on the lighting and turn it left to the minimum
brightness.
￭ Adjust basic brightness by turning the adjuster (7) (see figure 1). The basic
brightness must be set in such a way that the connected lamps are still visibly
lit when the control button is turned all the way to the left.

DANGER!
Electric shock when live parts are touched.
Electric shocks can be fatal.
Always disconnect before carrying out work on the device or load. For this, switch off
all the corresponding circuit breakers, secure against being switched on again, and
check that there is no voltage. Cover up adjacent live parts.
Only use original fuses! The replacement fuse is contained in the fuse holder.
￭ Remove the control button (4), the central plate (3) and the frame (2).
