The black Trunk In/Out pluggable connector allows replacement of

a Megablock without breaking the trunk connection to other devices

on the fieldbus segment. The F97 terminator supplied should be

mounted in the Trunk-out connection to provide termination when the

Megablock is located at the end of the fieldbus segment; alternatively,

if the segment is extended, it can be removed to ensure the correct

termination is maintained.

Spur connections to the Megablock are made using pluggable, grey,

screw-terminal or spring clamp terminal connectors. Wire terminations

can be made to the individual connectors before plugging them into

the Megablock. Devices can then be connected and disconnected

easily during commissioning. After commissioning, retaining screws

are tightened to secure each connector to the Megablock. Separate

numbered connections are provided for each spur drop.
