3.5.1 Electrostatic Discharge (ESD) Considerations
Important Note: To minimize hazards and ESD risks, maintenance
procedures not requiring power to the analyzer should be
performed with power removed.
Delicate internal electronic components can be damaged by static
electricity, resulting in degraded instrument performance or
eventual failure.
The manufacturer recommends taking the following steps to
prevent ESD damage to the instrument:
• Before touching any instrument electronic components (such
as printed circuit cards and the components on them)
discharge static electricity. This can be accomplished by
touching an earth-grounded metal surface such as the chassis
of an instrument or pipe or a metal conduit.
• To reduce static build-up, avoid excessive movement.
Transport static-sensitive components in anti-static containers
or packaging.
• To discharge static electricity and keep it discharged, wear a
wrist strap connected by a wire to earth ground.
• Handle all static-sensitive components in a static-safe area. If
possible, use anti-static floor pads and work bench pads.
3.5.2 Enclosure breakouts
There are four main enclosure openings to insert tubing and cables
(
