Ground Monitoring
Wire Attachments and Grounding – See Figure 12 for complete drawing of
Workstation Monitor 724 wire connections.
Tools required – Small blade, screwdriver, and wire cutter.
a) Using a screwdriver move DIP switch #2
on the Workstation Monitor 724 to the OFF
position to deactivate the work surface
audible alarm (Figure 4).
b) Locate the accessory package that contains
a 3M
™
Monitor/Table Mat Cord 2380D,
Workstation Monitor 724 ground wire (with
ring terminal), and the two-wire connector
plug.
c) Attach the Monitor/Table Mat Cord 2380D
(tinned wire end) to the work surface
terminal of the two-wire connector plug
by inserting into opening and securing
with screwdriver (Figure 5A or 5B).
Note: Disconnect the 3M
™
Monitor/
Table Mat Cord 2380D to check for
visual and audible high work surface
alarm condition and reconnect. If
the high work surface lamp (M) is on
before removing the Monitor/Table
Mat Cord 2380D, check for loose
connections or high resistance to
ground (>3.7 Megohms). Disconnect
the Monitor/Table Mat Cord 2380D
from the work surface and check the
resistance to ground by attaching one
lead of an ohmmeter to the connector
on the work surface and the other lead
to ground.
NOTICE
Do not physically connect the 3M
™
Monitor/Table Mat Cord 2380D
and the 3M
™
Workstation Monitor
724 ground wire together. The
ground wire for the work surface
and the ground wire from the
Workstation Monitor 724 must
be attached to separate electrical
grounds. However, by attaching
the wires to the same ground but
at a different physical location,
the Workstation Monitor 724 can
check for loose or lost connections
to ground. This would be indicated
by the high red work surface lamp
(M) illuminating.
