About this document
Purpose This document provides hardware installation instructions for B12 4T4R Procedures are provided for RRH handling, mounting, grounding, powering, and cabling.
Safety information For your safety, this document contains safety statements. Safety statements are given at points where risks of damage to personnel, equipment, and operation may exist. Failure to follow the directions in a safety statement may result in serious consequences.
Intended audience This document is intended for customers installing B12 4T4R
Safety labels The safety alert symbol is used on product labels and in this document to alert the user to important safety instructions.
How to use this document Prior to installing the radio, the installer should be familiar with the safety precautions, warnings, and product conformance statements. Required tools and materials recommended for installation, and a process checklist, are listed in Chapter "Tools, materials, and checklists" . The RRH installation instructions begin with Chapter "Transport, mount, and ground the radio" which provides mounting instructions for the radio. After it is mounted into position, the RRH can be connected to the network in accordance with the instructions given in Chapter "Connect interfaces" . This connection is made via fiber optic cables. In addition, instructions for connecting user and power alarms are provided in this chapter. Next, instructions to connect the radio to its power source is given in Chapter "Finish the installation" . The power source is DC power provided from an external power Converter or DC generator.
Conventions used
In this document, all parts are described as they are shipped. Metric parts are specified in metric units. Non-metric parts are specified in nonmetric units. Lengths and other measurements are given in metric units, with non-metric units given as equivalents for use in non-metric markets.
For manufactured parts, the following system of conventions is used: · Metric sizes of nuts, bolts, flat washers, and lock washers are identified by an uppercase letter M followed immediately by a size in
millimeters (example: M10) · American fractional sizes of nuts, bolts, anchor bolts, and washers are identified by a number followed immediately by a double apostrophe
(example: 3/8"). In the case of lengths measured in feet, "2 feet" is used rather than "2'" so that the single apostrophe is not overlooked.
The illustrations in this document do not contain all details and exceptions, but are rather intended to highlight main points. Dimensions are usually shown in millimeters, with inches in parenthesis. As an example, 680.0 (26.77) equals 680 millimeters or 26.77 inches. Wire gauges are specified in metric units. Equivalent sizes in the American Wire Gauge (AWG) system are given in the following table. Converter or DC generator.
Standard cross-sections and wire diameter of round copper conductors

Safety
General precautions for installation procedures
Notice Inadequate circulation Inadequate circulation of cooling air can cause some units to become too warm. This can lead to operational impairment. Cover all installation slots for unequipped units with blanking panels.
Touching a hot heater may cause burns. Do not touch the heaters. Before touching the units wait until they have cooled down, wear safety gloves and clothes.
Remarquer Circulation inadéquate Une mauvaise circulation de l'air de refroidissement peut faire en sorte que certaines unités deviennent trop chaudes. Cela peut entraîner une déficience opérationnelle. Couvrez tous les emplacements d'installation pour les unités non équipées avec des panneaux d'occultation.
Toucher un chauffe-chaud peut causer des brûlures. Ne touchez pas les appareils de chauffage. Avant de toucher les appareils, attendez qu'ils se soient refroidis, portez des gants de sécurité et des vêtements.
