Connect the Multi-axis
Stage
The installation procedure assumes you have prepared your system for correct
electrical bonding and understand the importance of electrical bonding for
correct operation of the system to which your linear stage belongs. If you are
unfamiliar with electrical bonding, the section
briefly describes and illustrates correct system grounding
techniques.
Attach the Ground Strap and Interface Cables
A ground strap and four cable connections are the only electrical connections
necessary between the multi-axis stage and the drive system. The flat surfaces on
the power and feedback connectors should align during connection, and
significant resistance should not be felt when tightening either connector.

For electrical safety, connect the ground screw on the chassis of the lower
linear stage to the groundbus for your system.
To reduce the effects of electromagnetic interference (EMI), bond the
stage with a braided ground strap, 12 mm (0.5 in.) wide minimum, to a
grounded metal surface. This creates a low-impedance return path for
high-frequency energy.
ATTENTION: Plan the installation of your multi-axis stage so
that you can perform all cutting, drilling, tapping, and welding
before installing the multi-axis stage. Be careful to keep any
metal debris from falling into the stages. Metal debris or other
foreign matter can become lodged in a stage, which can result in
damage to the stage or its components.
SHOCK HAZARD: To avoid hazard of electrical shock, perform
all mounting and wiring of the multi-axis stage prior to applying
power. Once power is applied, connector terminals may have
voltage present even when not in use.
