v
Do not put the ESD mat near any electrical circuit that has power turned on. The internal resistance
(1 megohm) in the ESD cable limits the current if it touches a high voltage.
v
Do not put the ESD mat near a grounded surface. Ground the ESD mat only through the ESD cable. The ESD
cable supplies a high resistance to ground for your safety. If the ESD mat touches a grounded surface, the high
resistance in the ESD cable is bypassed, which causes the ESD mat not to work as expected.
