Monitors worksurface mat 1.
Connect the white mat monitor cord here.
O. Operator 1 Remote Jack:

Installation
1. Determine the mounting location of the Zero Volt
Monitor. The front panel should be visible to both
operators.
2. Determine the mounting locations of the operator
remotes. Be sure to install the remotes at a distance
that enables its leads to reach the back of the
monitor.
3. Install tinned wire ends of the mat cords to their
appropriate screw terminal block located at the back
of the monitor.
4. Attach the worksurface mats to ground using the
green mat ground cords. Install the ring terminal end
of the cord to an appropriate ground point. Attach
the snap terminals to the snaps on the worksurface
mats.
5. Install the tinned wire end of the green monitor
ground cord to the ground terminal located at the
back of the monitor. Install its ring terminal to an
appropriate ground point. Be sure to use a different
ground point than the one used for the mats. The
face plate screw of a grounded AC wall outlet may
provide a convenient connection point.
6. Route the mat cords from the back of the monitor
to the snaps on worksurface mats. The white cord
is for worksurface mat #1. The black cord is for
worksurface mat #2.
7. Insert the operator remote cables into their
appropriate jacks located at the back of the monitor.
The white cable is for operator #1. The black cable
is for operator #2.
8. Connect the power adapter to the power jack
located at the back of the monitor. Plug the power
adapter into a proper AC power outlet. The monitor
is now powered.
