Grass Valley PFR 500/E Dec 10 2001 - Manual (Page 74)

Appendix A
74 PFC500/E Instruction Manual November 17, 2000
Operating limits
The ambient temperature specification is measured at the front door inlet. The site
must have air conditioning of the correct size and placement to maintain the specified
ambient temperature range. The air conditioning must be able to handle the BTU
requirements of the PFC 500/Es.
.
IMPORTANT: The operating limits for temperature and humidity must not be
exceeded inside the closed cabinet in which thePFC 500/Es are mounted. Mounting
equipment in a cabinet directly above or below a PFC500/E does not restrict air
flow to the PFC500/E, because air flows through the PFC 500/E from
front-to-back. Cabinet doors must not impede the front-to-back air flow.
