1.0 Installation of 3M
™
Anti-Fatigue Mats 9900 and 9920
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 (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.
To reduce the risk associated with hazardous voltage due to Anti-Fatigue Mats 9900 Series
being used in areas requiring insulating type matting:
• Anti-Fatigue 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 Anti-Fatigue Mats being installed
with an incorrect grounding lead:
• Do not use Anti-Fatigue Mats without using the correct grounding cord, 3M
™
Ground Cord 3040.
To reduce the risk associated with hazardous voltage due to Anti-Fatigue Mats being grounded
through an alternate ground path:
• Grounded equipment or objects should not contact the mat. This could bypass the 1.0 MΩ 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.
