2.0 INSTALLATION
2.1 Rack Mounted
The power supply can be rack mounted in a standard 19" rack cabinet. It must be supported by two
side shelf supports to hold the power supply weight. Caution should be used as the supports should
not block the power supply side air input and exit.
The rack vertical height required is 8 3/4 inches. The chassis depth is 21". An additional 3" is
required for clearance of terminals, plugs and wiring. The panel should be secured to the rack cabinet
by the six mounting holes provided.
2.2 Cooling
The power supply is air cooled by an internal fan that pulls air into the power supply chassis from the
rear and side panels. The power supply is approximately 85% efficient, thus, 1100 watts of heat must
be removed from the cabinet. The customer must ensure a free flow of air is maintained through the
cabinet and keep the ambient air temperature at the input to the power supply below 104
°
F (40
°
C) or
even cooler (<35ºC) if 400VAC unit is operated at less than 360 VAC input.
The main air input to the power supply is on the right side. Auxiliary air inputs are on the rear panel.
The fan is located on the left side. All air passages must be unobstructed. If air filters are used on the
cabinet air input, they should be checked on a regular schedule for dirt and dust accumulation.
The inverters have a temperature sensor that will shut down and latch out further operation if an
over temperature condition should occur.
