Installing the air assembly kit
WARNING: Before starting to install the
kit, ensure the machine is safe to
work on.
1. Secure the air regulator, vertically upright, to
a suitable surface using the mounting
bracket. This must be within 25 m of the
NC4.
2. Locate a source of clean air to
ISO 8573-1:Air quality class 5.7.–, and
connect it to the regulator inlet. Where
possible, use air that exits directly from the
machine tool air filter unit.
If the compressed air source is suspected of
being contaminated (e.g. if it is direct from the
machine shop supply, if the machine tool filter is
dirty, or if it is downstream of an oil mist
lubricator) then a second air filter may be
required. A suitable filter unit is available from
Renishaw (see “Parts list – air supply
accessories” on page 78).

What to do next
After you have finished installing the air
assembly kit, you should install either the NC4
fixed system or the separate system.
Do not switch on the air supply or set the air
pressure until the NC4 system and NCi-4
interface have been installed and electrical
power has been applied.
