Grounding
Once the DRO is mounted to the machine, it must be grounded. Using a 3 prong grounded outlet is sufficient; however
we also recommend connecting a ground terminal on the back of the DRO unit to the machine ground with AWG 12
wire. It is important to ensure that the machine itself is properly grounded. Note, these are just general guidelines, always
follow national and local electric codes!
Failure to ground the unit may cause equipment damage and/or electric
shock!
Cables
Before attempting to connect the encoders to the DRO, ensure that they are properly installed on the machine. Check the
encoder manual for the installation procedures. Encoder alignment can drastically affect the accuracy of the DRO system,
and severely misaligned encoders will result in premature wear and/or permanent damage.
Once the linear encoders are properly installed, plug the encoder cables into their respective axis inputs on the back of
the unit. Switch the DRO power off before connecting the encoders. Move each axis along its full range of motion to en-
sure that cables are not caught on any parts of the machine and do not rub against sharp edges that may cause damage
to the cables. Secure the cables such that they can not fall into the lubricant tray when disconnected from the DRO.
