Electrostatic Sensitive Devices - Siemens SIMOTICS XP Operating Instructions Manual

Ignition hazards
The assessment of operating risks and local operating conditions and the necessary
monitoring methods must be clarified and made binding by the system operator in
consultation with the responsible supervisory authority. The required measures must be
adhered to at all times. The machine manufacturer cannot provide any generally applicable
recommendations. Please observe the information in these operating instructions.
Note

Material damage due to electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These components can be damaged or destroyed if they are not handled correctly. To protect
equipment against damage, follow the instructions given below.
• Only touch electronic modules if you absolutely have to work on them.
• The body of the person concerned must have been electrostatically discharged and
grounded immediately before any electronic modules are touched.
• Electronic modules should not be brought into contact with electrically insulating
materials, such as:
– Plastic film
– Plastic parts
– Insulating table supports
– Clothing made of synthetic fibers
• Always place the modules on conductive and grounded surfaces.
• Always pack, store and transport electronic modules or components in conductive
packaging, such as:
– Metallized plastic or metal containers
– Conductive foam material
– Domestic aluminum foil
