Instructions
•  Please handle the product with care. The product can be damaged if crushed, 
struck or dropped, even from a low height.
•  Also observe the safety and operating instructions of any other devices that are 
connected to this product.
•  If you have doubts about how the product should be operated or how to safely 
connect it, consult a qualied technician.
•  Maintenance, adjustment and repair work may be carried out only by an expert or 
a specialised workshop.
•  If you have any questions that are not answered in these operating instructions, 
please contact our technical customer service or other professionals.
b) Connection and operation
•  The product‘s design complies with protection class I. Only an earthed mains 
socket connected to the public power supply may be used as power supply to 
the product.
•  The mains socket into which the weekly timer is inserted must be easily acces-
sible.
•  The weekly timer is equipped with a child safety lock. Only when the pins of the 
power plug are placed in both openings of the front socket at the same time will 
the child-lock mechanism release the opening.
Nevertheless, take special caution when children are around. Children cannot rec-
ognise the danger arising from the incorrect use of electrical devices. There is a 
risk of a life-threatening electric shock!
•  The product is only intended for use in dry indoor locations. No part of the product 
should become damp or wet; never handle it if your hands are wet! Never place 
the product in the immediate vicinity of a bathroom, shower, bathtub or the like. 
Lethal hazard due to electric shock!
•  Use the product only in a temperate climate, never in a tropical climate.
•  Do not operate the device in environments where there are high levels of dust, 
ammable gases, vapours or solvents. There is a danger of re and explosion!
•  Never use the weekly timer in a vehicle.
•  Do not connect the product to the power supply immediately after it has been 
transferred from a cold room into a warm one (e.g., during transport). The conden-
sation that forms might destroy the device or lead to an electric shock. Allow the 
product to reach room temperature. Wait until the condensation has evaporated. 
This might take several hours. Only after this should the product be plugged into 
the power supply and put into use.
•  Never pull out the power plug from the front socket of the weekly timer by pulling 
on its cable. Always pull out the plug from the front socket by gripping the area 
provided for this purpose on its sides.
•  Do not overload the weekly timer. Observe the connected load in the chapter 
“Technical data”.
•  Always pull out the weekly timer from the mains socket before cleaning it or when 
the device will not be in use for a long time.
•  Never pour any liquids above or next to the product. You run the risk of causing a 
re or a fatal electric shock. 
However, if liquid has entered the device, immediately turn off the power supply to 
the mains socket at which the weekly timer is connected (turn off the fuse/circuit 
breaker/residual current operated circuit breaker of the associated circuits). Only 
then can you unplug the weekly timer from the mains socket and contact a special-
ist. Do not use the product any longer. 
•  Do not connect in series! This can lead to an overloading of the weekly timer! 
There is a risk of re!
•  Do not operate while covered! At higher connected loads, the weekly timer be-
comes warm, which can lead to overheating and potentially a re if covered!
•  Only voltage-free when the plug is withdrawn!
•  Never touch a weekly timer that shows signs of damage, as this could cause a 
fatal electric shock!
First, switch off the mains voltage to the socket to which the weekly timer is con-
nected (switch off at the corresponding circuit breaker or remove the safety fuse 
or switch off at the corresponding RCD protective switch, so that all poles of the 
mains socket are disconnected). 
Only then can you remove the weekly timer from the mains socket. Do not use the 
damaged weekly timer any longer and dispose of it in an environmentally-friendly 
manner.
