General precautions

CS 1000 equipment is based on solid state circuitry that is sensitive to
static electricity and environmental conditions. Follow the precautions in
this chapter to avoid personal injury and equipment damage.
Wear an antistatic wrist strap when handling circuit cards to prevent
damage caused by static electricity.

Circuit cards

Handle the circuit cards as follows:
•
Wear an antistatic wrist strap before handling circuit cards.
•
Handle the cards by the card stiffeners and edges only. Do not touch
the contacts or components.
•
Keep the cards installed in the system as much as possible to avoid
dirty contacts and unnecessary wear.
•
Set the cards on a protective antistatic bag. If an antistatic bag is
not available, hold the card, or set it in a card slot unseated from the
connectors.
•
Unpack or handle the cards away from electric motors, transformers,
or similar machinery.
DANGER
To avoid the danger of electric shock, be careful when working
with power equipment and connections. Warning notices are
