2260-ALM-RS485 INSTALL INSTRUCTIONS

2. Introduction In a split Radio Base Station (RBS) architecture the typical RBS consists of a Base Band Unit (BBU) and Remote Radio Heads (RRH) connected by cabling. Power to the RRH is provided through copper cables traveling from the base station to the top of the tower or roof top. This creates a conductive path, making the active equipment at the top and the base of the site vulnerable to damage by direct lightning strikes. Protection systems installed in front of both the BBU and the RRH must be able to withstand direct lightning currents in order to protect the sensitive equipment. Raycap’s RRH solutions featuring Strikesorb® SPD technology significantly enhance the reliability & availability of the RRH site by providing superior electrical protection at the RRH and BBU, and also enable flexible fiber optic and power cable management solutions.

The RCMDC-2260-RM-48 is suitable for installation for Network Telecommunications Facilities, (Central Office), Outside Plant (Remote Termainal Facilities), and locations where the NEC applies (Customer Prem Locations).

3.1 PrerequisitesThis document describes the steps to achieve communication link from an existing 6 OVP RM at the base, to the newly installed 12 OVP (RVZDC-6627-PF-48) at top of the tower.

Installers of Raycap’s RRH surge protective and fiber/power management solutions must be industry professionals who have attended training on the proper installation of the equipment by Raycap and/or the mobile operator. Installers are required to read this installation guide thoroughly prior to installation of the Raycap RRH protection equipment.

Installers shall obey all general and regional installation and safety regulations related to work on high voltage installations, as well as regulations covering correct use of tools and personal protective equipment. Use this equipment only for the purpose specified by the manufacturer. Do not carry out any modifications or fit any parts that are not recommended by the manufacturer. This could cause electric shock or other injuries.

Procedure4. Removal of Existing PCB

Below is a picture of an un-connected 2260. In this retrofit kit you will be replacing the main circuit board with a new circuit board providing the communication link to a 12 OVP (RVZDC-6627-PF-48) at the top of the tower. The following step-by-step instructions will lead you through the installation process.

(Installed cables and wires not shown for clarity)

4.1 WARNING – Disconnect or disable the DC power source to the product prior to beginning this installation.

4.2 Remove 4 screws securing touch guard shielding to access power cables. Set touch guard and screws aside.

4.3 Make note of each cable connection to ensure proper connections are established when reinstalling -48V, Return, and Ground cables.

Remove -48V, Return, and Ground cables from ALL terminals.

4.4 To remove touch guard to access PCB terminals, remove the 4 white plastic screws and set aside. This touch guard will not be used when installing the 2260-ALM-RS485 kit.

4.5 Make note of each wire connection to ensure proper connections are established when reinstalling alarm wires.

ATTENTION – Electrostatic sensitive devices. ESD mitigative procedures, such as wearing wriststraps are to be used during installation and maintenance.

Remove alarm wires from ALL terminals.

4.6 Remove the 4 stand-offs using a 1/4" nut driver and set aside.

4.7 Remove the 4 Philips head screws securing the PCB and set aside.

4.8 Slide PCB down to disconnect from front-PCB.

4.9 Disconnect ribbon cable from PCB.

4.10 Remove PCB and set aside. This will not be reused.
