NOTICE
Electrostatic discharge
Electronic modules contain components that can be destroyed by electrostatic discharge.
These modules can be easily destroyed by improper handling.
To protect your equipment against damage, follow the instructions given below.
● Never touch electronic modules unless absolutely necessary in the course of maintenance
● If the modules have to be touched, the body of the person concerned must be
● Electronic modules should not be brought into contact with electrically insulating materials
● Always place electrostatic sensitive devices on conductive bases.
● Always pack, store and transport electronic modules or components in conductive

Risk of explosion due to electrostatic discharge
Electrostatic discharge poses a potential ignition source. In an explosive atmosphere, there
is a risk of an explosion. This can result in death, serious injury or material damage.
Please comply with ESD protective measures.
