Safety information: Caution

Check the set nominal voltage of the installation (operating instructions and type plate).
As long as the power supply is switched on, always observe the greatest caution when per-
forming measurements on powered components and maintenance work on plug-in cards,
PC boards and covers.
To protect against the electrostatic discharge (ESD):
– Always wear the wristband before performing any work on PCB boards and modules.
– Only transport PC boards in suitable protective packaging.
– Always place PC boards on a grounded conducting base, and do not process the PC
boards anywhere else.
– Only use grounded soldering irons.
Only use tools and testers suitable for the job. Do not use broken tools and testers, inspect
them regularly.
Find out the location of the main switch for the power supply of the system. Follow the
appropriate instructions.
Install cables in such a way that they do not pose an accident risk (i.e. so that they do not
trip anybody up) and also so that they are not damaged.
