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-
sure the protection class and ESD protection.

Dimensions

The Beckhoff Bus Terminal system is characterized by low physical volume and high modularity. When
planning a project it must be assumed that at least one Bus Coupler and a number of Bus Terminals will be
used. The dimensions of the Bus Couplers are independent of the fieldbus system.
