3.4.1 Installing the adjustable mounting rails

The adjustable mounting rail kit contains a pair of mounting rails (left and right handed) that are fitted to each

side of the cabinet and secured by two screws – front and back. The rails can be extended to any length

between 543 mm and 925 mm and are compatible with most standard 19 inch rack assemblies of 600 mm to

900 mm depth.

Figure 3.7 Adjustable mounting rail installation

1. Remove five screws from the front of both sides

of the UPS.

2. Attach a mounting handle assembly (B4) to both

sides of the UPS enclosure, using the holes

vacated in the previous step to secure the

handles in place.

3. Extend the adjustable mounting rail and hold in place (see Figure 3.6).

4. Align the two holes in the back of the adjustable mounting rail with the

holes in the cabinet’s vertical fixing rail.

5. Identify and mark the two vertical fixing rail holes to which the adjustable

mounting rail is to be fixed.

6. Clip captive nuts (B5) to the two vertical fixing rails holes identified above.

7. Secure the rear of the adjustable mounting rail to the vertical fixing rail

using two dome headed bolts (B6).

8. With the rear of the adjustable mounting rail secured in place, and the adjustable mounting rail extended, identify

the four fixing points that will align with the equipment mounting handles and clip four captive nuts to the required

fixing points.

Note: The fixing points will vary according to the equipment height (2U, 3U, 4U) as shown in Figure 3.8.

9. Secure the adjustable mounting rail to the rack’s front vertical fixing rail using two countersunk bolts (B7) and

adapter plate (B3) (see Figure 3.8).

10. Repeat the steps 1 to 9 above to fit the second adjustable mounting rail.

11. When both mounting rails are fitted, carefully insert the UPS / Battery enclosure into the rack so that it rests

correctly on the rails. Then secure it in place using the four dome head bolts (B6) as shown in Figure 3.8.

12. The UPS should now be commissioned as detailed in paragraph 3.5.1 before it is put into service.

WARNING: The UPS / Battery enclosure is heavy. When lifting the equipment ensure that adequate

manpower is available and any mechanical lifting aids are suitable for the weights involved.

WARNING: When inserting the enclosure into the rack ensure that it is held level. If it is inserted at an

angle it could pivot about the back of the mounting rail runners if the front of the enclosure is tilted

upwards.
