A.4 Temperature derating for the power entry module of a VM600 rack
The AC-input rear panels with mains sockets used by ABE04x racks have a compact filtered
power entry module with an IEC type C14 connector (IEC 60320).
As shown in Figure A-1, this power entry module requires temperature derating when the
VM600 rack operates in environments with temperatures greater than 50°C.
Basically, the power entry module (and VM600 rack) can operate at 100% power for
temperatures up to 50°C, but for temperatures greater than 50°C it must be derated linearly
to 50% power at 70°C.
