Emerson N400C, N410C manual Workstation Precautions

Removal and Replacement Preliminaries

■Store reusable electrostatic-sensitive parts from assemblies in protective packaging or nonconductive foam.

■Use transporters and conveyers made of antistatic belts and roller bushings. Ensure that mechanized equipment used for moving materials is wired to ground and that proper materials are selected to avoid static charging. When grounding is not possible, use an ionizer to dissipate electric charges.

4.6Workstation Precautions

Use the following grounding precautions at workstations:

■Cover the workstation with approved static-dissipative material (refer to Table 4-2).

■Use a wrist strap connected to a properly grounded work surface and use properly grounded tools and equipment.

■Use conductive field service tools, such as cutters, screwdrivers, and vacuums.

■When using fixtures that must directly contact dissipative surfaces, only use fixtures made of static-safe materials.

■Keep the work area free of nonconductive materials, such as ordinary plastic assembly aids and Styrofoam.

■Handle electrostatic-sensitive components, parts, and assemblies by the case or PCM laminate. Handle these items only at static-free workstations.

■Avoid contact with pins, leads, or circuitry.

■Turn off power and input signals before inserting or removing connectors or test equipment.
