Handle all printed circuit boards as little as possible and by the edges
only. Leave the boards in their protective packaging until instructed to
install them.

Follow the instructions in the next section to attach an antistatic wrist
strap.
Attaching an Antistatic Wrist Strap
Use a disposable or reusable antistatic wrist strap when replacing boards in
the base unit.
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 used again.
➤
To attach a reusable antistatic wrist strap:
1. Secure the metal clip to the ground loop as shown in the following
figure. The SCSI cable is not shown for clarity.
2. Slip the elastic end of the wrist strap snugly around your bare wrist.
Note: The metal conductor bead in the elastic must contact bare skin.
