3.5 Electrostatic Discharge
This section provides information and instructions on Electrostatic Discharge
(ESD) product safety. ESD is defined below.
ESD
A static electric charge accumulates when a body rubs
against clothes, slides against a chair, when shoes rub
against a floor, or when ordinary plastics are handled,
and so on. The electrostatic charge can remain for a
considerable length of time and is discharged when the
body comes into contact with conductive material.
An ESD wrist strap must be used when working with ESD sensitive components,
even in equipment rooms fitted with ESD protective floor covering. Although
ESD floor covering reduces the risk of ESD, if the wrong type of shoes are
used, or if the person is already charged when they enter the room, the floor
covering in itself does not protect from this, and therefore an ESD wrist strap
must be used.

Figure 16 ESD wrist strap
The ESD wrist strap contains a resistor with resistance greater than 1 M in the
cable to protect the operator. The resistance value is low enough to discharge
the electrostatic voltage. The ESD wrist strap must be connected to ground.
Instructions for ESD Wrist Strap Use
1. Place the ESD wrist strap around your wrist and insert the connector at the
other end to the ground (earth) terminal on the equipment.
2. Always use the wrist strap when and where its use is required.
Note: Test the ESD wrist strap regularly.
