2 Important Safety Information
2.8 Prevention of ESD Damage
ATTENTION!
An ESDS device (electrostatic discharge-sensitive device) is any device at risk of damage or
malfunction due to electrostatic discharges (ESD) and thus requires special measures to prevent
such damage or malfunction. Systems and modules with ESDS devices usually bear the following
symbol:
Symbol Indicating Devices with ESDS Components
The following measures will help to protect ESDS components from damage and malfunction.
When preparing to dismantle or install devices:
Ground your body (for example, by touching a grounded object) before touching sensitive devices.
Ensure that you wear a grounding strap on your wrist when handling such devices. These straps must
in turn be attached to an uncoated, non-conductive metal part of the system.
Use only tools and devices that are free of static electricity.
When transporting devices:
Devices must only be touched or held by the edges. Never touch any pins or conductors on the device.
When dismantling or installing devices:
Avoid coming into contact with persons who are not grounded. Such contact may compromise your
connection with the earth conductor and thus also compromise the device’s protection from any
static charges you may be carrying.
When storing devices:
Always store devices in ESD-proof ("antistatic") bags. These bags must not be damaged in any way.
ESD-proof bags that are crumpled or have holes cannot provide effective protection against
electrostatic discharges.
ESD-proof bags must have a sufficient electrical resistance and must not be made of conductive
metals if the device has a lithium battery fitted on it.
