GENERAL CAUTIONS

REPLACEMENT AND ADJUSTMENT
3.1 GENERAL CAUTIONS
Using the ESD Ground Strap
Purpose
The purpose of the ESD (Electrostatic Discharge) ground strap is to preserve the
inherent reliability and quality of electronic components handled by the Service
Representative. The strap should be used whenever handling the circuit boards or
any other ESD sensitive components.
Procedure
NOTE: All procedures requiring use of the ESD ground strap will contain a caution
referring to this procedure.
1 Switch off the main power switch.
2. Make sure the power cord connects the machine to the wall outlet. The power
cord and wall outlet must have ground.
3. Connect the claw end of the grounding cord to a chassis ground, such as earth
wires screwed to chassis ground, unpainted frame or an unpainted bracket
secured to the frame.
4. Connect the snap end of the blue cord to the snap on the adjustable wrist strap.
5. Place the adjustable wrist strap securely on the wrist. Wait for one minute to let
the electrostatic be discharged from your body.
6. ESD sensitive components can now be handled without causing any ESD re-
lated damage.
7. New replacement PCBs and ESD sensitive components, as well as old defec-
tive PCBs should be handled during unpacking and repacking using the ESD
ground strap. During the transfer from or to the packaging material, the PCB
should be placed on the ESD bag the replacement PCB came in.
WARNING
Turn off the main power switch and unplug the machine before attempting
any of the procedures in this section.
CAUTION
ESD Hazard! ESD (Electrostatic Discharge) can cause software crashes,
data and/or communications problems. Failure to use proper ESD proce-
dures will cause damage to electronic components (example: PCBs). ESD
problems can be minimized by maintaining all machine ground connec-
tions, ensuring the proper handling of circuit boards/ sensors, refer to this
procedure 3.1.
- Use ESD protection when working near PCBs. Failure to use ESD protec-
tion is likely to result in a PCB failure.
