● Precautions Against Electrostatic Problems
The GC1000 system uses numerous IC components. When handling cards with IC
components mounted on them for maintenance or setting changes, take full precau-
tions against electrostatic problems.
These precautions are summarized below.
(a) 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.)
(b) Whenever mounting or demounting cards into or from a product, wear a wrist
strap grounded via a 1 M
Ω
resistance. Connect the wrist strap to any ground
terminal near the ground wire or to any unpainted part of the grounded frame.

(c) When servicing cards on the bench, place them on a conductive sheet
grounded via a 1 M
Ω
resistance, wearing a wrist strap as in (2) above. Keep
easily-chargeable plastic materials away from the bench.
(d) Never touch components mounted on the cards, the pattern side, connectors,
pin components, etc. with bare hands, unless using a wrist strap and a conduc-
tive sheet.
(e) Wrist straps and conductive sheets are available from Yokogawa Engineering
Service (YSV).
