Section 2.2.1 Safety Regulations
3BSE 002 415R701 Rev A 2-17
2.2.1.2 Machine Safety
CAUTION
Observe the following safety rules:
• Avoid discharges of static electricity by grounding both yourself and tools before handling
circuit boards and other parts of the equipment.
• Use the grounded wristband installed in the cabinet when handling parts of the system.
• Handle the circuit boards carefully, particularly those which contain MOS components
which can be damaged by static electricity discharges. Note the warning label on the
circuit boards.
• Use, as far as possible, the grounded wristband when handling boards not stored in
envelopes of conductive plastic. This gives optimum protection against static electricity
discharges.
• Always store circuit boards in envelopes of conductive plastic when not installed in the
system rack.
• Always switch off the voltage before extracting a board which cannot be exchanged while
under voltage. See Chapter 5, Maintenance. Wait a sufficient time for the capacitors to
discharge.
• Switch off voltage to the system and withdraw all boards at least 20 mm before electrical
welding is performed near the controller system.
• A warning label is fixed in the system to draw attention to possible damage by ESD
(Electro Static Discharge).
Figure 2-7. Warning Label regarding ESD
All elektronik är känslig
för ESD (elektrostatisk
urladdning). För att und-
vika onödiga skador vid
hantering av kretskort
rekommenderas använd-
ning av systemjordat
handledsband med in-
byggt skyddsmotstånd
samt antistatisk för-
varingspåse för korten.
All electronic devices are
sensitive to ESD (electro-
static discharge) effect.
To avoid accidental dam-
ages while handling PC
boards, it is recom-
mended to wear wrist
strap earthed to the
chassis. Wrist strap has
to have built-in protective
resistor. Antistatic bag
has to be used to store
and transport the PC
boards.
