5.4 General Remarks
The size and weight of the wall-mount case is such that 2/3 persons may be needed to lift the
equipment into position. Test the mechanical installation in the interests of safety, before any
electrical, RF, or optical connections are made.
The equipment must be located on a smooth, flat, perpendicular surface, sheltered if possible,
that is made from a material suitable for bearing the weight of the enclosure, (brick or
concrete is recommended). If the installer is in any doubt about the suitability of a site it is
advised that he/she consult with an appropriately qualified Structural Engineer.
It is also important in determining the location of the case that space is allowed for access to
the front, sides and beneath the equipment to enable maintenance work to be carried out. The
door must be able to fully open but not to obstruct other equipment when doing so.
The location should ideally be served with steel conduits to carry all the cables to and from
the case.
5.5 Electrical Connections
The mains power supply is connected to the IP65 connector located on the bottom/side
surface of the case. It is recommended that the connection is made by a qualified electrician,
who must satisfy himself that the supply will be the correct voltage and of sufficient
capacity.
All electrical and RF connections should be completed and checked prior to power being
applied for the first time.
5.6 RF Connections
Care must be taken to ensure that the correct connections are made with particular attention
made to the base station Tx/Rx ports. In the event that the base transmitter is connected to the
Rx output, damage to the equipment will be done if the base station transmitter is then keyed.
Ensure that connections are kept clean and are fully tightened.
