1.1.3 Servicing Work on Electronic Components
ATTENTION (ESD sticker for labelling electrostatically sensitive devices)
Electronic modules can be damaged by even slight static electricity. For this reason they are marked with this
symbol.
You should observe the following rules when carrying out servicing work on electronic modules :
●
Switch the machine off and disconnect it from the power supply.
●
Put on an antistatic armband.
●
Do not remove electronic modules from their antistatic envelope until just before you fit them.
●
Do not put the electronic module down on anything except a grounded antistatic mat.
●
Make sure that the components inserted in the IC sockets are seated firmly in the sockets.
●
When fitting the board hold it only by its edges and do not touch either the components or the conductor
tracks on the board.
●
Touch a bare metal surface before fitting the board in the machine.
●
Make sure that all electrical connections have been made correctly.
●
When fitting plugged-in modules make sure that they are seated correctly and firmly in their unit. If this is
not the case, short circuits could occur and the connections burn out.
●
Pack the defective modules in the electrostatic envelopes provided.
