77Appendix A Plumbing and Connection OptionsA.1 Safety informationWhen making any plumbing or wiring connections, the followingwarnings must be adhered to, as well as any warnings and notesfound throughout the individual sections. For more safetyinformation, refer to Safety information, page 9.DANGERAlways disconnect power to the instrument when making anyelectrical connections.CAUTIONThe enclosure may tip forwards if it has not been fixed inplace. Only open the enclosure if the enclosure is properlymounted.A.1.1 Electrostatic Discharge (ESD) ConsiderationsImportant Note: To minimize hazards and ESD risks, maintenanceprocedures not requiring power to the analyzer should beperformed with power removed.Delicate internal electronic components can be damaged by staticelectricity, resulting in degraded instrument performance oreventual failure.The manufacturer recommends taking the following steps toprevent ESD damage to the instrument:• Before touching any instrument electronic components (suchas printed circuit cards and the components on them)discharge static electricity. This can be accomplished bytouching an earth-grounded metal surface such as the chassisof an instrument or a metal conduit or pipe.• To reduce static build-up, avoid excessive movement.Transport static-sensitive components in anti-static containersor packaging.• To discharge static electricity and keep it discharged, wear awrist strap connected by a wire to earth ground.• Handle all static-sensitive components in a static-safe area. Ifpossible, use anti-static floor pads and work bench pads.
