Appendix A Plumbing and Connection Options
A.1
Safety information
When making any plumbing or wiring connections, the following
warnings must be adhered to, as well as any warnings and notes
found throughout the individual sections. For more safety
information, refer to
DANGER
Always disconnect power to the instrument when making any
electrical connections.
CAUTION
The enclosure may tip forwards if it has not been fixed in
place. Only open the enclosure if the enclosure is properly
mounted.
A.1.1
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 a metal conduit or pipe.
•
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.
