♦
Handle all printed circuit boards as little as possible and by the edges
only. Leave new parts in their protective packaging until you install
them.
♦
To maintain ground, do not unplug the power cord from the base unit,
AC outlet, or UPS.
♦
After opening the base unit, attach the antistatic wrist strap described in
the next section.
Attaching an Antistatic Wrist Strap
Use a disposable or reusable antistatic wrist strap when servicing or
upgrading the workstation.
Note: There is no increased risk of electrical shock when using the wrist
strap. If the wrist strap does not snugly contact bare skin, static
protection will not be effective.
➤
To attach a disposable antistatic wrist strap:
1. Remove the wrist strap from the envelope.
2. Unfold the wrist strap and wrap the exposed adhesive side firmly
around your bare wrist.
3. Peel the liner from the wrist strap copper foil. Attach the adhesive
side of the copper foil to a bare flat metal surface (electrical ground)
inside the base unit.
Note: After using the disposable wrist strap once, it cannot be reused.
