3.5 Location, Mounting and Cooling
This power supply is fan cooled. The air intake is at the front panel and the exhaust is at the rear
panel. Upon installation allow cooling air to reach the front panel ventilation inlets. Allow minimum
10 cm (4”) of unrestricted air space at the front and the rear of the unit.
The power supply should be used in an area that the ambient temperature does not 50°C.
3.5.1 Power Supply Rear Support Bracket
Complete the following instructions to install the rear support bracket for mounting the RMX-410x
and RMC-412x programmable power supplies in a NI equipment rack.
1. In the desired rack location, screw the support brackets to rack internal rails as shown in
figure 2-5. The kit includes four #10-32 UNF screws of 12.7 mm (0.5”) length.
2. Once rear brackets are tightly fastened on both sides of the rack, the power supply equipment
can be placed on top of the brackets.
WARNING:
Mounting the power supplies into the rack requires at least two people to support the chassis during
installation.
WARNING:
To prevent injury when mounting or servicing the chassis in a rack, you must take precautions to
ensure the system remains stable.
3.6 AC Source Requirements
The RMX-410x series can be operated from a nominal 100V to 240V, single phase, 47~63Hz. The
input voltage range and current required for each model is specified in Chapter 2. Ensure that under
heavy load, the AC voltage supplied to the power supply does not fall below the specifications
described in Chapter 2.
3.7 AC Input Power Connection
WARNING:
Some components inside the power supply are at AC voltage even when the On/Off switch is in
the ”Off” position. To avoid electric shock hazard, disconnect the line cord and load and wait two
minutes before removing cover.
3.7.1 AC Input Connector
An IEC connector is provided on the rear panel for connecting the unit to the AC power source with
an AC cord. The IEC connector also provides the safety ground connection while the AC cord is
plugged into an appropriate AC.
