Always follow the ESD-prevention procedures described in
Discharge, page
-vii, to avoid damage to equipment. Damage from static discharge can cause
immediate or intermittent equipment failure.
Ensure that the chassis cover is secure. The chassis allows cooling air to flow effectively within it.
An open chassis allows air leaks, which could interrupt and redirect the flow of cooling air from
internal components.
Electrical equipment generates heat. Ambient air temperature might not be adequate to cool
equipment to acceptable operating temperatures without adequate circulation. Ensure that the room
in which you operate has adequate air circulation.
With a dry, clean, well-ventilated and air-conditioned area.
That maintains an ambient temperature of 10° to 35°C (50° to 95°F).
Keep tools and chassis components off the floor and away from foot traffic.
Clear the area of possible hazards, such as moist floors, ungrounded power extension cables, and
missing safety grounds.
Keep the area around the chassis free from dust and foreign conductive material (such as metal
flakes from nearby construction activity).
