1.1.3 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.
