Besides the proper grounding of the installation, the signal cables must be shielded and
twisted-pairs for greater necessary protection. The shield must be connected to a specific
point avoiding ground loops which could cause undesirable effects. This grounding of the
shield is done at the DRO’s ground terminal.
Each element of the machine-tool/DRO installation must be connected to ground through
the established main ground points. They will be conveniently set at a point close to the
machine-tool itself and properly connected to the Main Ground Point.
When a second ground point is required, it is recommended to join both points by a cable
with a section of 8mm
2
or greater (or two 4mm
2
).
It must be verified that the resistance measured between each connector housing and ground
is less than 1 Ohm.
