Electrostatic Discharge (Esd) Considerations; Electrical Access Ports - Hach LANGE astroTOC UV/Turbo Analyzer Manual Del Usuario

To prevent shock hazards from ground currents in inadequate ground systems, connect the shield at
only the analyzer end. Do not connect the shield wire at both ends.

Electrostatic discharge (ESD) considerations

Potential Instrument Damage. Delicate internal electronic components can be damaged by static
electricity, resulting in degraded performance or eventual failure.
Refer to the steps in this procedure to prevent ESD damage to the instrument:
• Touch an earth-grounded metal surface such as the chassis of an instrument, a metal conduit or
pipe to discharge static electricity from the body.
• Avoid excessive movement. Transport static-sensitive components in anti-static containers or
packages.
• Wear a wrist strap connected by a wire to earth ground.
• Work in a static-safe area with anti-static floor pads and work bench pads.

Electrical access ports

Make electrical connections through the electrical access ports. Refer to
Remove plugs as necessary.
To keep the environmental rating and for safety:
• Make sure that all electrical access ports that are not used have the supplied plugs installed.
• Use sealing-type PG11 fittings or equivalent for power cords, wiring and conduit. Refer to
on page 14.
