Service manual 3
If you have to leave the unit unattended during servicing
or maintenance, disconnect the unit from main power
supply to protect people, who may touch the unit, from
electric shock.
This unit should be used only in areas that are provided
with a protective earth connection to ensure an equipo-
tential ground connection.
Caution - electrostatic discharge
Electrostatic Discharge (ESD) can damage or destroy
electronic components.
When servicing the unit take precautions to avoid elec-
trostatic build up and discharge (ESD). Follow the rec-
ommendations for the prevention of ESD that are used
in the country in which you are working. If no recom-
mendations are available, follow the guidelines below:
- Leave all new or replacement circuit boards and
electrical parts in their protective packaging until the
boards are needed.
- Before handling circuit boards and electrical parts
make sure that any static electricity charge that has
built up in you body is discharged.
- When examining and checking circuit boards use an
antistatic wrist wrap which is connected to a ground
point through a 1 Mohm current limiting cable. For a
ground point use water pipes, radiators or other ob-
jects that are known to be connected to the ground.
Also use a cable to connect the unit to the same
ground potential as the wrist wrap.
- When handling circuit boards hold them by their
edges and do not touch any components or connec-
tors.
- If an antistatic mat is used, connect the wrist wrap
to the mat and the mat to the ground potential.
- Wash the wrist wrap and check that it is in good
condition frequently.
