10. Push the conduit onto the barbed tting and t the securing O-clip.
11. Remove the adjuster pack screw covers and secure the adjuster pack assembly to the mounting
bracket.
12. Route the conduit through the machine (for minimum bend radius values, refer to the table on
page3-3). A range of accessories are available for neat installation; see the NC4 non-contact tool
setting accessories data sheet (Renishaw part no. H-2000-2223).
NOTE: Before routing conduit and air pipes through the machine, ensure straight adaptors and
blanking caps are tted to the free ends of each pipe (refer to the gure on page 3-4). This prevents
the ingress of debris into the air pipes.
13. Repeat steps 4 to 12 for the other NC4 unit.
14. Route the cables to the electrical cabinet, taking care to avoid situating them next to sources of
electrical noise such as motors or power cables.
15. Route the barrier air pipe to the air preparation pack
NOTE: 20 m (65.62 ft) of 6 mm (0.23 in) diameter pipe is supplied with the NC4 installation pack.
When routing the barrier air supply, it is recommended that this pipe is used as far as possible
(typically to the machine bulkhead) then reduced in diameter closer to the NC4 unit.
16. Remove the straight adaptors and blanking caps from the end of the air pipes.
17. Before connecting any pipe to the NC4 unit, use the air regulator to purge the pipe and remove any
debris.
