2.3 The unit is sensitive to ESD
Description
ESD (electrostatic discharge) is the transfer of electrical static charge between two
bodies at different potentials, either through direct contact or through an induced
electrical field. When handling parts or their containers, personnel not grounded
may potentially transfer high static charges. This discharge may destroy sensitive
electronics.
Safe handling
Use one of the following alternatives:
• Use a wrist strap. The wrist strap button is located inside the controller.
Wrist straps must be tested frequently to ensure that they are not damaged
and are operating correctly.
• Use an ESD protective floor mat.
The mat must be grounded through a current-limiting resistor.
• Use a dissipative table mat.
The mat should provide a controlled discharge of static voltages and must
be grounded.
