Fastening of the Cubicles

WARNING
hazard of installing under inadequate conditions If a cubicle is found to be raised after the next one is installed, there is a risk of experiencing vibrations, depending on the load. Failure to follow these instructions can result in death, serious injury, or equipment damage.

NOTICE
hazard of installing under inadequate conditions Before positioning the switchgear at its installation site, ensure that the fastening points are at the correct level. Unevenness should not exceed ± 2 mm/m and there should not be a height difference of more than 6 mm over the entire width of the switchgear. Failure to follow these instructions can result in equipment damage.

NOTICE
hazard of inappropriate assembly Comply with precise measurements for the placement of the cubicle, as the positioning of the first cubicle determines the placement of the remaining cubicles. Failure to follow these instructions can result in equipment damage.

Follow the below steps to fasten the cubicle to the floor on standard civil engineering works:

Position first cubicle on the floor in accordance with the switchgear-specific space assignment plan, refer to the Ground Plan of a MCSeT Switchgear within a Switchgear Room
.
Remove the cable compartment cover. Refer to Access to the Cable Compartments, User Guide (BQT6904800).
Once the cubicle is positioned:
- Verify that the cubicle front is correctly aligned both horizontally and vertically.
- If necessary, raise the cubicle and insert shims below the cubicle near the fastening points until the correct horizontal position is achieved, refer to Figure 20
  .
Fasten the cubicle with screws to the two fastening points on both the front end and the rear end.

⁽¹⁾ Add plates as needed.

The additional fastening variants are available on request. For details, contact the manufacturer.

Follow the below steps to fasten the cubicle on C-channel rails on standard civil engineering works:

Drill holes into the C-channel frames at the intended cubicle fastening point, refer to Figure 21.
Position the cubicle on the C-channel rails, aligning the fastening points.
Insert dowel pin and other suitable fasteners (provided by Schneider Electric).
Securely fasten the cubicle to the C-channel rails at the designated points.

NOTE:

The additional fastening variants are available on request. For details, contact Schneider Electric.
C-channel rails are not be provided by Schneider Electric.
