PSI 9000 DT Series
Standing surface (handle in -45° position)
2.3.3.3 Installation in a 19” system
The optionally available 2U mounting frame (see
1.9.4
) can be used to install the power supply in a 19” cabinet or
other 19” related system with at least 2U of space. The frame will center the device horizontally on the front plate
of the frame. The entire front of the device remains accessible.
Due to the relatively short depth of the DT housing, the rear side is probably or only hardly accessible once the
frame is installed and tied. It’s thus recommended to make all necessary connections before actually inserting the
frame into the cabinet.
The mounting frame requires to install and use support rails in the 19” system. The rear part of the
frame is 449 mm wide and can rest on small rails capable of supporting the weight of the device.
Recommended procedure (also see Figure 7 to Figure 10 below):
1. Remove the carrying handle from the power supply device:
a. Rotate the handle into -90° position. See
Figure 7
below.
b. Simultaneously pull on both sides of the handle until the axis can slip out of the housing (also see section
2.3.3.1) .
2. Remove the front frame (1). Also remove the rear frame (1) by loosening the 4 screws.
3.
Place the mounting brackets (2) and fix them with 2x screw M4x10 and 2x contact disc M4 each. Here it’s
recommended to use a 90° Torx screw driver (ratchet etc.).
4. Screw the 4 hex spacers (3) M3x10 into the threaded holes which were used to hold the rear frame (
Figure 10
).
5. Place the rear part of the mounting frame (4) on the hex spacers and fix it with 4 screws M3x6 and 4 lock wash -
ers M3 (5). Select the window which fits a PSI 9000 DT rear side layout ( Figure 11 ).
6. If long enough, connect all rear side cables before inserting the frame. If the cables are not long enough, it’s
best to insert the frame into the 19” system first.
7. Fully insert the frame and tighten the front with typical 19” system front tightening screws (not included).
8. Connect the front side DC output to your load.
