Instructions for ESD protection

Destruction of the devices by electrostatic discharge possible!
The devices contain components at risk from electrostatic discharge caused by improper handling.
• Please ensure you are electrostatically discharged and avoid touching the contacts of the device directly.
• Avoid contact with highly insulating materials (synthetic fibers, plastic film etc.).
• Surroundings (working place, packaging and personnel) should by grounded probably, when handling
with the devices.
• Each assembly must be terminated at the right hand end with an EL9011 or EL9012 bus end cap, to en-

• DIN Rail TH 35-7.5 with 1 mm material thickness (according to EN 60715)
• DIN Rail TH 35-15 with 1,5 mm material thickness
Pay attention to the material thickness of the DIN Rail
Terminal Modules und EtherCAT Modules of KMxxxx and EMxxxx series, same as the terminals of
the EL66xx and EL67xx series does not fit to the DIN Rail TH 35-15 with 2,2 to 2,5 mm material
thickness (according to EN 60715)!
