2.4 Location, Mounting, and Ventilation
Use the power supply in rack mounted or in benchtop applications.
2.4.1 Rack Mounting
WARNING
Ensure that the screws for the rack mount brackets do not extend more than
1/8" (3.0 mm) into the sides of the unit.
The power supply is designed to fit in a standard 19" (483 mm) equipment rack. To install:
1. Use the rack mount brackets at either side of the front panel to install the power supply in a rack. To
mount the supply for relay rack applications, move the brackets back to their alternate locations which
are midway along each side.
2. Provide adequate support for the rear of the unit without obstructing the ventilation inlets on the sides
of the unit. Use a support bar such as Hammond RASB19WH2 at the rear of the unit. Follow the
manufacturer's instructions to install the support bar.
Rack mount slides are not suitable for the 1200 Watt unit, however, standard mounting rails are available from
the manufacturer.
2.4.2 Ventilation
Whether you place the power supply in a rack or on a bench, allow cooling air to reach the ventilation inlets on
the sides of the unit and allow 4" (10 cm) of unrestricted air space at the rear of the unit for the fan exhaust. Any
ventilation space at the top and bottom of the supply will further lower internal operating temperatures.
Check Section 1.3.6 for the operating ambient temperature range and the operating altitude specification.
