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 operated 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
