Ventilation
The performance of the rectifier or other power modules can be limited if the ventilation is restricted. The
rectifier is cooled by drawing air into the front of the unit with a single fan. This air passes through the rectifier
cooling the electronics and exiting the rectifier at the rear. For efficient airflow:
Check the air at the front of the rack is at ambient temperature and not being heated by other
•
equipment.
That the rectifier shelf has at least 3"/75mm clear horizontal space behind it. This space must be clear
•
of cables and any other components that may restrict air movement.
N
: if multiple rectifier shelves are installed then there should be at least 3"/75mm clear horizontal
OTE
space per shelf.
Check the free space in the rack continues vertically to the exhaust point at the top of the rack,
•
without impediment.
Check the hot exhaust air does not re-circulate to the front of the rack as this will be drawn into the
•
rectifiers again, in effect raising the apparent ambient temperature.
Check the operating environment is low dust and fiber.
•
Pay particular attention to the quality of rectifier air intake. Insects, sand, and other
extraneous matter ingress seriously impacts the performance of the rectifiers.
