Recommended Air Flow Clearance
Be sure that there is adequate clearance for air ventilation around
the 8720MC-RPS Regenerative Power Supply. Cooling air flows
from the bottom to the top of the units. For best cooling effect, do
not mount the 8720MC-RPS Regenerative Power Supply directly
above each other. The figure below shows recommended air flow
clearance.
When mounting the 8720MC-RPS Regenerative Power Supply, pay
attention to the following:
• Mount the units vertically.
• When two or three units of 8720MC-RPS Regenerative Power
Supply are installed in parallel, install the master unit at the
rightmost end viewed from the front side.
• Be sure that the ambient temperatures surrounding the units is
between -10 to 50 degree C (14 to 122 dgree F). In case of
Model 8720MC-RPS190BM and 8720MC-RPS190BS units, the
ambient temperature is -10 to 40 degree C (14 to 104 degree F).
To cool down the temperature in the cabinet, provide sufficient
space to allow adequate air flow over the components. If
necessary, add circulating fans to assure good convective heat
transfer.
• Do not mount any devices behind the units. This area must be
kept clear of all power wiring (control power wiring, main
power supply wiring and DC bus power wiring).
