5.2.3
830W Airflow Requirements and Temperature Rise
The power module supply incorporates one 60mm fan. The fan will provide no less than 14
CFM airflow through the power supply when installed in the system
CFM airflow through the power supply when installed in the system
The power supply meets UL enclosure requirements for temperature rise limits. All sides of the
power supply, with exception to the air exhaust side, are classified as “Handle, knobs, grips,
etcetera, held for short periods of time only.”

5.2.4.1
AC Input Voltage Specification
The power supply operates within all specified limits over the following input voltage range (see
the following table). The power supply shall power off if the AC input is less than the 75-80VAC
range. The power supply operates properly starting at 80-85VAC input voltages.

5.2.4.3
AC Line Fuse
The power supply shall have a single line fuse, on the line (Hot) wire of the AC input. The input
fuse shall be a slow blow type. AC inrush current shall not cause the AC line fuse to blow under
any conditions. No protection circuits in the power supply shall cause the AC fuse to blow
unless a component in the power supply has failed. This includes DC output load short
conditions.
