PROFIBUS-PA T-Connector with bus terminator

EEx(ia) with bus terminator

Comment:

The customer’s earthing concept is to be followed.

The screen-housing connection is not used in the connecting box. If necessary, a connection

must be added.

On the EEx(ai) version, an external bus terminator is required at the end of the bus system.
