GROUND RING INSTALLATION
The ground ring assembly includes a floor flange which interfaces
with the brush ring located on the perimeter of the turntable. The
floor flange provides constant electrical contact with the user’s
ground plane and is usually installed with the turntable.
Mounting methods vary according to user specifications. Clearance
holes are provided along the outside perimeter of the ground ring
as a means of attaching the ring to a customer supplied ground
plane. These mounting holes are provided at evenly spaced
intervals.
1. When attaching the ground ring, first center and level the
turntable assembly into the turntable pit. The cutout diameter in
the floor needs to be per the Dimensional Drawing for the
table.
2. Install the floor flange around the turntable. A gap of 5/16” to
7/16” should be maintained around the turntable. Trim flange
to length by match drilling with floor and installing ¼-20
flathead screws.
3. Install wear strip on inside of floor flange by aligning with top
of turntable flange.
4. Make sure that pre-drilled mounting holes in wear strip are
aligned to 2.54cm (1.00”) from bottom of flange.
5. Trim wear strip to size after ensuring that the full
circumference of the flange is covered by the strip.
6. Using pre-drilled holes on wear strip as a template, drill holes
through the flange.
7. Secure wear strip to floor flange using 6-32 x 3/8” hex head
stainless steel thread cutting screws (furnished with turntable).
8. Apply conductive grease (furnished with turntable) on wear
strip along the brush contact area (approximately 1” to 2” from
the top of the strip).
