1 Important Information
1.3 Handling Electricity
The following work may only be done by trained and qualied electricians:
Work on electrical components.
Work on an open device still connected to the mains supply.
General precautions before starting maintenance work:
Find out where the emergency and power switches are so that they can be quickly thrown in an emergency.
Disconnect the current supply before carrying out the following work:
Installing or removing power units.
Working in the immediate vicinity of open power supply components.
Mechanical check of power supply components.
Modifying circuits in the device.
Test the zero potential of the device parts.
Check the working area for possible sources of danger, such as wet oors, defective extension cables, defective
protective conductor connections.
Additional precautions in the case of exposed voltages:
Ask a second person to remain near the working site. This person must know where the emergency and power
switches are, and how to switch the current off if danger arises.
Only use one hand to work on electric circuits of devices that are switched on. Keep the other hand behind your
back or in your pocket.
This prevents electricity from owing through your own body.
1.4 Procedure in Case of Accidents
Act calmly and with great care.
Avoid danger to yourself.
Switch off power.
Request medical assistance.
Give rst aid, if necessary.
