Dust on devices may cause electrostatic discharge and result in poor contact for
connectors or metal connection points. This problem can shorten the life span of
devices and cause faults.
The equipment room must be free from explosive, conductive, magnetically-
permeable, and corrosive dust.

Use dustproof materials for ground, wall, and ceiling construction.
Use screens on the door and windows facing outside. The outer windows
should be dust-proof.
Clean the equipment room regularly and clean the air filter door monthly.
Wear shoe covers and ESD clothing before entering the equipment room.
