4.2.2.

Connecting the bus cover

The bus cover provides three M12 connectors.

Two M12 connectors (D-coded, according IEC 61076-2-101) serve for PROFINET connection.

•

For voltage supply use A-coded M12 connector only.

•

For the bus lines both D-coded M12 connectors may be used at will.

•

Seal up the unused cable gland using a sealing bolt (included in the delivery).

There is no need to proceed any manual settings inside the bus cover. PROFINET does not require setting a

node ID and terminating resistor like Profibus. All address parameters are configured by the projecting tool

(e.g. Siemens

Assembly of basic encoder and bus cover:

•

Carefully plug the bus cover onto the D-SUB connector of the basic encoder, then press it over the seal

taking care not to tilt it.

•

Tighten both fastening screws firmly in the same direction.

•

The bus cover must fully rest on the housing of the basic encoder and be firmly screwed on.

The encoder housing and braided shield of the connecting cable are only ideally connected if the bus cover is

resting fully on the basic encoder (positive locking).
