Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the strap to an unfinished chassis surface.
Place the BBU on an antistatic surface or in a static shielding bag. If the BBU will be returned to
the factory, immediately place it in a static shielding bag.
Avoid contact between the battery and clothing. The wrist strap protects the battery from ESD
voltages on the body only; ESD voltages on clothing can still cause damage.
Do not remove the wrist strap until the installation is complete.
