Grounding The Work Area; Recommended Materials And Equipment; Operating Guidelines - HP EliteDesk 405 G4 Desktop Mini Maintenance And Service Manual

Grounding the work area

To prevent static damage at the work area, use the following precautions:
Cover the work surface with approved static-dissipative material. Provide a wrist strap connected to the
●
work surface and properly grounded tools and equipment.
Use static-dissipative mats, foot straps, or air ionizers to give added protection.
●
Handle electrostatic sensitive components, parts, and assemblies by the case or PCB laminate. Handle
●
them only at static-free work areas.
Turn off power and input signals before inserting and removing connectors or test equipment.
●
Use fixtures made of static-safe materials when fixtures must directly contact dissipative surfaces.
●
● Keep work area free of nonconductive materials such as ordinary plastic assembly aids and Styrofoam.
● Use field service tools, such as cutters, screwdrivers, and vacuums, that are conductive.

Operating guidelines

To prevent overheating and to help prolong the life of the computer:
● Keep the computer away from excessive moisture, direct sunlight, and extremes of heat and cold.
Operate the computer on a sturdy, level surface. Leave a 10.2 cm (4-inch) clearance on all vented sides
●
of the computer and above the monitor to permit the required airflow.
