Precautions Against Electrostatic Damage
IMPORTANT
Electrostatic discharge may damage the operation panel. Handle them after discharging static
electricity.
When handling cards with IC components mounted on them for maintenance or setting changes,
take full precautions against electrostatic problems.
• When storing or carrying cards, enclose them in a conductive bag or antistatic bag. (Cards
as shipped by Yokogawa are enclosed in a conductive bag or antistatic bag labeled with
cautions against electrostatic problems.)
• When servicing cards, wear a wrist strap grounded via a 1 MΩ resistance. Connect the wrist
strap to a ground terminal.
• When servicing cards on the bench, wear a wrist strap and place them on a conductive
sheet grounded via a 1 MΩ resistance. Keep easily-chargeable plastic materials away from
the bench.
• Never touch components mounted on the cards, the pattern side, connectors, pin
components, etc. with bare hands, unless using a wrist strap and a conductive sheet.
