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
signicantly enhance the reliability & availability of the RRH site by providing superior
electrical protection at the RRH and BBU, and also enable exible ber optic and power cable
management solutions.
The RCMDC-2260-RM-48 is suitable for installation for Network Telecommunications Facilities,
(Central Ofce), Outside Plant (Remote Termainal Facilities), and locations where the NEC
applies (Customer Prem Locations).
3.1 Prerequisites
This 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 ber/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 specied by the
manufacturer. Do not carry out any modications or t any parts that are not recommended by
the manufacturer. This could cause electric shock or other injuries.

Procedure
4. Removal of Existing PCB
Below is a picture of an un-connected 2260. In this retrot 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.
