Installation Instructions

3. Before Starting the Installation

Site Prerequisites, Continued

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

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 the

following paragraph

Lightning and surge protection.

Lightning and

surge

protection

A: For Ethernet (SF/UTP) Cables:

Lighting surge protection device (LSP) is required to minimize possibility of

equipment damage to any equipment connected to the unit from lighting

induced surges.

B: Power Supply Cables (for radio unit direct powering):

A power surge protection device (PSP) is required to minimize possibility of

equipment damage from lightning induced surges or power supply surges.

For LSP and PSP details and instructions refer to please refer to item 1 of

Reference manuals on page 14.
