Raycap has made all reasonable efforts to ensure that the instructions contained in this document
are adequate and free of material errors and omissions. Raycap will, if deemed necessary, explain
issues which may not be covered by this document.
The contents of this document are subject to revision without notice due to continued progress in

1.2 Warnings
Please read this manual prior to use to become familiar with the product’s numerous features and
operating procedures. To maintain the maximum degree of safety, follow the sequences as outlined.
Before using the product, read all instructions and cautionary markings on the product and on any
equipment connected to the product.
CAUTION – Unless otherwise noted, product usage that is not recommended or sold by the product
manufacturer can result in risk of re, electric shock, or injury to persons.
CAUTION – Do not operate the product if it has been damaged in any way. Return damaged
products to their manufacturer for repair or replacement.
CAUTION – Do not disassemble the product as incorrect reassembling can risk electrical shock or re.
WARNING – Disconnect or disable the DC power source to the product prior to beginning its
installation. Ensure that the DC power source to the product remains de-energized until the
completion of the installation and after all connections have been veried to be correctly congured.
ATTENTION – Electrostatic sensitive devices. ESD mitigative procedures, such as wearing
wriststraps are to be used during installation and maintenance.
ATTENTION – Installation of the hybrid cable requires an approved hanger to be used no more than 3
feet from the entrance of the Raycap unit. Refer to cable manufacturer’s instructions for proper hardware.
CAUTION – Do not bend ber-optic cables beyond their minimum bend radius. Bending the cables
beyond their minimum bend radius can damage the cables and cause problems that are difcult to
diagnose.
CAUTION – Do not let ber-optic cables hang free from the connector. All ber must be secured
against movement in wind while maintaining enough slack to prevent any tension along the run. Do
not allow fastened loops of cables to dangle, which stresses the cables at the fastening point.
WARNING – Do not look directly into a ber-optic transceiver or into the ends of ber-optic cables.
Fiber-optic transceivers and ber-optic cables connected to transceivers emit laser light that can
damage your eyes.

INSTALL INSTRUCTIONS RCMDC-6627-PF-48
WARNING: Do not stare into the laser beam or view it directly with optical instruments even if the interface
has been disabled.
1. If the ber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.
2. If the optical transceiver is covered by a rubber safety cap, remove the cap. Save the cap.
3. Prior to connecting the ber to the device, clean it using proper industry accepted cleaning methods.
4. Insert the cable connector into the optical transceiver.
5. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in
a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.
For conditions other than those described above, please contact a Raycap Account Representative at
[phone], [phone], [e-mail], or www.raycap.com
Thank you for choosing quality products from Raycap.
2.0 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 signicantly 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.
3.0 Overvoltage Protection Package Contents
• One (1) Enclosure including the SPDs, cable glands, the DC distribution and
ber management parts.
• Incorporated Mounting bracket and related accessories.
• Mounting hardware accessories (bolts, washers and nuts)
3.1 Prerequisites
This document describes how to install the RCMDC-6627-PF-48 on-site and how to mount, and connect it to
external interfaces.
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 specied by the manufacturer. Do not carry out any modications or
t any parts that are not recommended by the manufacturer. This could cause electric shock or other injuries.

3.3 General Install Information
Whenever installing a RCMDC-6627-PF-48 at the top and connecting it at the base to a
RCMDC-4520-RM-48x, RCMDC-2260-RM-48, or a RCMDC-3315-PF-48, the (4520),
(2260) or (3315) should include a retrotted alarm board to communicate properly to the
newly installed (6627).
Whenever installing a (6627) at the tower top, the alarm board rotary switch should be in
the default #1 position.
Any unit installed at the base connected to a (6627) at the top, whether it be a (4520),
(2260) retrot, (3315) retrot, or another (6627) will be at rotary switch position 2. If there
are subsequent units daisy chained at the base they will take the next number on the rotary
switch #3 and on as more units are daisy chained together. As many as 4 units can be
daisy chained together the last being at rotary switch #5 position.
