Preparation of
the installation
premises
• Access to the installation premises must be facilitated during the
installation period.
• Entrances must be large enough to enable the easy transportation of the
new equipment.
• The floor must be level, smooth and able to bear the load of the
equipment.
• The roof must be engineered to bear the weight of the service personnel
and the outdoor equipment.
Network port
distributors
• Suitable electrical network port distributor should be available.
• The exact location of the network port distributor, as well as the network
ports to reserve, should be known prior to installing the equipment.
• Also, all the reserved ports on the network port distributors should be
qualified and tested before realizing the network connections with the
equipment.
Power supply
cable routing
Routing of AC or DC power supply power cable should be implemented as
prescribed by the local regulations regarding outdoor electrical installations.
Cable conduits
Appropriate cable conduits should exist for the routing of installed cables.
Grounding
Ensure the following:
• To make a protective earth connection, use the grounding point located
close to the radio unit.
• A grounding point (designated GND) should be located close to the
mounting position of the radio unit (0 to 2 m).
• The grounding point must be connected to grounding cable at least 16
mm
2
diameter.
• An appropriate, low-resistance grounding system as specified by the local
regulations is required.
• The equipment will be connected to this grounding point, via the supplied
grounding cable. This can provides only partial protection against
Lightning-induced power surges. For more information regarding
equipment protection against Lightning-induced power surges please refer
to Lightning & Surge protection.
