CAUTION:
To reduce the risks associated with improper cleaning of the mats, which, if not avoided may result in
electrostatic overstress damage to static sensitive electronic components:
• Follow proper cleaning procedure outlined in this instruction manual.
• Do not use hydrocarbon solvents such as paint thinner.
• Do not use oil-based cleaning solutions such as Murphy

Oil Soap or Pine-Sol

Static Control Anti-Fatigue Mats 9900 and 9920
WARNING
To reduce the risk associated with hazardous voltage due to 9900 Series Mats being used in areas requiring
insulating type matting:
•
M 9900 Series Mats are electrically conductive -- do not use this matting in areas with
possible exposure to high voltage.
To reduce the risk associated with hazardous voltage due to 9900 Series Mats being installed with an
incorrect grounding lead:
•
Do not use M 9900 Series Mats without correct grounding cord, M™ Ground Cord 040.
To reduce the risk associated with hazardous voltage due to 9900 Series Mats being grounded through an
alternate ground path:
• Grounded equipment or objects should not contact the mat. This could bypass the 1.0 M
Ω
resistor in the ground
cord.
To reduce the risk associated with back strain due to the heavy weight of the mats:
• Follow safe lifting procedures during installation or moving.
1. Pre-clean the floor area where the mat is to be installed.
2. Place mat into desired location.
3. Attach the supplied ground cord (3M Ground Cord 3040) to the female snap on the mat.
4. Route ground cord to ground point and connect the ring terminal on the other end of the ground cord to
an approved ESD ground.
Note: If the mat is being placed on an ESD conductive/dissipative tile or epoxy flooring it may not be
necessary to connect a ground cord to the mat. The ESD flooring may be able to provide a sufficient
ESD ground path for the mat. Verify the surface to ground resistance following measurement method
outlined in ESD Standard ANSI/ESD S7.1. This can be done using the 3M
™
Test Kit 701, which includes a
megohmmeter and electrodes (see Optional Accessories section) or an equivalent measurement system.
