SECTION 3
Installation When Attaching to a Static Control Work Surface
The 3M
™
Wrist Strap Monitor Model 725 can be used to ground a work surface
while providing a monitored grounding point for an operator. To ground a
work surface, the Wrist Strap Monitor
Model 725 contains a snap located
on its bottom cover, that is connected
internally to the monitor’s ground cord.
To use this feature there must be a 3M
™
Female Snap Fastener Model 3034,
10 mm, snap fastener attached to the
grounding layer of the work surface.
Simply align the male snap on the
monitor with the female snap on the
work surface and press downward on
the monitor. The work surface is now
automatically grounded through a one
megohm resistor by the Wrist Strap
Monitor Model 725.
3M
™
Work Surface 8200 Series use the female 10 mm (3M Female Snap
Fastener Model 3050) snap fastener for grounding. 3M
™
Work Surfaces 1800,
8300 and 8800 Series use the female 10 mm (3M Female Snap Fastener Model
3034) snap fastener for grounding. In addition all 3M
™
Portable Field Service
Kits 8500 Series include the 10 mm (Female Snap Fastener Model 3034) snap
fastener.
Use of an optional 3M
™
Stand-By Jack 3057 at the work station extends the life
of the monitor’s input jack. The user disconnects the wrist strap ground cord
from the wrist band and plugs into the Stand-By Jack 3057 which is mounted at
the work station. Plugging into the Stand-By Jack 3057 prevents the Wrist Strap
Monitor Model 725 from continuously alarming when disconnected from the
wrist band.
The system is now ready for use.
Note: Although the work surface is grounded by
the 3M
™
Wrist Strap Monitor Model 725, it is
not monitoring the ground to the work surface.
