Mount the Vision System
The vision system provides mounting holes for attachment to a mounting surface.
CAUTION: The vision system should be grounded, either by mounting the
vision system to a fixture that is electrically grounded or by attaching a wire
from the vision system's mounting fixture to frame ground or Earth ground. If a
ground wire is used, it should be attached to one of the four mounting points on
the back plate of the vision system and not to the mounting points on the front
of the vision system.
1. Align the holes on the mounting surface with the mounting holes on the
vision system.
2. Insert the M4 screws into the mounting holes and tighten using a 2.5mm hex
wrench; the maximum torque is 0.90 Nm (8 in-lb).
Note: The maximum insertion depth of the M4 screws should be
6mm in the rear housing and 3.75mm in the front housing, plus the
thickness of the mounting material used.
