4.10 Mounting the enclosure
4.10.1 Concrete slab
Use the tagline to guide the enclosure as it is lifted. As the enclosure is lowered, align the mounting bolts and
slowly lower the enclosure into place.
CAUTION: Follow all local safety practices and guidelines while lifting the enclosure. As the
enclosure is lowered, ensure that it remains as level as possible and lines up with the anchoring
bolt locations. Ensure the rubber mat is in the proper position. Open the door and proceed with
leveling the enclosure and securing it into place.
Leveling the enclosure

Four 0.125" shims are provided with the enclosure. Before securing the enclosure, make sure that it is level.
Place the shims as close as possible to the bolts.

Check that the enclosure is level font-to-back and side-to-side.

A shim may need to be added under one or two of the corners of the enclosure. To place a shim, take just
enough weight off the enclosure to slide the shim into place.

Allow the full weight of the enclosure to rest on the shims, and then check the level again.

Once the enclosure is level, tighten all bolts to the appropriate torque. After securing the enclosure, remove the
slings and lifting eyes.
4.10.2 Steel platform
If the steel platform is located at ground level, the procedures are the same as those for a concrete slab.
4.10.3 Roof mounting
CAUTION: The mounting platform must be installed before the enclosure can be installed. All grounding
must be in place before the installation.

Place the enclosure onto the roof using either a freight elevator with access to the roof, or by using a crane or
hoist on the roof.

Do not remove the enclosure from its pallet until it is on the roof and is ready to be positioned.
4.10.4 Installing multiple enclosures side-by-side

If two or more enclosures are to be installed adjacent to one another, install the environmental components of
the interface kit before bolting the enclosures into place.

For detailed procedure, refer to the next chapter and drawings 747-602-08, 747-603-08, or 747-607-08.
