Location Requirements

Install the XG in a location that meets the following requirements:

Condition Description

Clean The XG should not be exposed to metal filings or any other form of conductive contamination.

Cool The ambient air temperature should be between 0 °C–50 °C (32 °F–122 °F) for best performance.

Ventilated Whether operating the power supply in a rack or on a bench, allow air to reach the ventilation

inlets on the front and rear of the unit for cooling. The direction of airflow is from the front to the
back of the unit. Ventilation space at the top, bottom or sides of the power supply is not required

WARNING: Shock hazard

Ensure that any mounting screws do not penetrate more than 1/8 in. (3.0 mm) into the bottom
and/or the back of the unit.

Mounting Option A: 1U Rails

1U rails are to support the XG rack mount packages. The rail is a flanged rail type and only
available for a rack depth of 25 inches.

The part number to order this option is RM-XG1.

Tools and Materials Required

To mount and connect the XG, you will need the following tools and materials:

• Screwdriver (Phillips head, #2)

• Standard carpenter’s level

• Eight #10-24 × ¼" (30 mm) Phillips head screws.

Installation Procedures

To install the power supply in an equipment rack:

1. Ensure that your rack resembles the rack shown in Figure 2, and has inner holes within the
specified dimensions.

2. Find the 1U space in which you wish to install your power supply in the specific rack.

3. Place the lower plain flange of the RM-XG1 rail at the lowest point of the 1U space. If it is
placed correctly, a hole on the inner flange of the vertical rack will line up to the oval
mounting slot in the rail.

4. Using the carpenter’s level for accuracy, install the rail using two #10-24 screws.

5. Tighten the screws to a torque of 20.5 to 22.5 in-lbs.

6. Repeat on the opposite side, using the level to ensure both rails align.

7. Slide the XG assembly onto the rails, and against the front rails of the rack.

8. If there are four front mounting locations available, then install four #10-24 screws. Tighten
the screws to a torque of 20.5 to 22.5 in-lbs. If there is only one hole available on either side,
then the RM-XG1 rails are not installed correctly.
