All work on the device should only be carried out 

by trained and skilled electricians. Observe the 

country-specific regulations.

The outputs may carry an electrical current even 

when the device is switched off. Always discon-

nect the fuse in the incoming circuit from the sup-

ply before working on connected loads.

With the rotary dimmer insert (hereafter referred to as 

"dimmer"), you can use a rotary knob to switch and dim 

ohmic loads such as
• Incandescent lamps and 
• 230 V halogen lamps.

½

The device can be damaged.
• Always operate the device with the specified 

minimum load. 

• Protect the circuit with a 10 A fuse if further 

loads are to be looped on the X terminal of the 

device.

|

The maximum allowed load is reduced due to the 

decreased heat dissipation when you do not in-

stall the device into a single standard flush-

mounted mounting box:

* If several factors apply, add the load reductions togeth-

er.

• You switch the connected lamps on and off by press-

ing the rotary knob A once.

• By turning the rotary knob B, you dim the lamps 

brighter or darker.

The connected lamp doesn't switch on.
• Check the fuse, replace if necessary.
• If there is an overload due to the fact that the operating 

temperature is too high, it will not be possible to switch 

the dimmer back on and it must be replaced.

1 Remove the covers.
2 Prise the fuse holder out using a screwdriver.
3 Remove blown fuse A and replace with replace-

ment fuse B.
