Site Installation Considerations for an External Enclosure

An External Enclosure is installed with a choice of three methods:

Ground mounted
Wall mounted
Pedestal mounted

Ground Mounted

When installing the enclosure to the ground, two systems are available. The first and most common is the system termed 'Direct Bury'. The second system uses a Transformer Root.

Inground root (direct bury)
This mounting system is popular for installing 'CatWalk' enclosures and consists of an inground root, which is typically a four-sided box without a top or bottom. Appropriate cable access windows are provided. The inground root is lowered into an excavated hole.
The cable ducts are installed prior to back filling with concrete to secure the enclsoure in position. Detailed installation instructions are available on Data Sheet 101 available from Cannon Telecomms on request.

Transformer root
An alternative system which is used with the larger 'StreetWise' and 'AirWave' enclosures. A concrete pad is cast in-situ with its top surface 350mm below ground level. The 'Transformer Root' is sited on the top of the concrete pad and secured in position with expanding bolts or pre-positioned studs. The external enclosure is then bolted to the 'Transformer Root' or may be supplied pre-fitted to it, when it could be designed to include lifting features. Once bolted in position, the ground is back-filled around the 'Transformer Root' and the surface made good. Detailed installation instructions are available on Data Sheet 102 available from Cannon Telecomms on request.

Wall Mounted

Depending on the size and weight of the cabinet, various wall mounting solutions are available. Please speak to our technical staff who will be able to help and advise on the various options available.

Pedestal Mounted

This external enclosure is generally of a small size. The pedestal to which it is attached can be a small in-ground root or an above ground tubular structure for cabling to the equipment within the enclosure. Due consideration must be given to the groundworks to ensure stability during service. Our technical staff will be able to advise on various solutions.
