2.4. Electrostatic Discharge (ESD) Precautions
Warning
: The I-Gate 4000 PRO terminal contains devices that can be
damaged by accidental introduction of ground or foreign voltages. Therefore,
read carefully all points in this section regarding electrostatic discharge (ESD)
and other electrical precautions before proceeding with installation.
Certain tools and test equipment commonly used on electromechanical systems
should never be used on the I-Gate 4000 PRO. These include: battery buzzers, AC
wire-wrap guns, electric soldering irons and guns, test picks and test lamps.
The following precautions must be observed:
!
The I-Gate 4000 PRO uses various Metal Oxide Semiconductor (MOS) devices.
All personal tools, test equipment and metal objects that come into contact with
MOS devices must be electrically grounded. Any static or foreign voltage that is
introduced into these devices may damage them permanently.
!
Do not use tools or test equipment, such as test lamps and picks that draw an
appreciable amount of current when attached to the system.
!
Do not use tools or test equipment that could introduce foreign voltages into the
system. For example, a battery-powered buzzer operates on only six or nine
volts, but the voltage introduced across the buzzer coil when the magnetic field
collapses can reach a momentary peak in excess of 100V, which can destroy
solid-state devices.
!
Use only hand-powered or battery-powered wire-wrap guns in equipment
cabinets. AC-powered wire-wrap guns and lead verification equipment can be
used at the distribution frames only if all cabling has been disconnected from the
cabinet.
!
When handling I-Gate 4000 PRO cards, always use an anti-static strap.
