1.1 Changes in RRU3931E Installation Guide

This section describes the changes in RRU3931E Hardware Description.

Draft A (2016-03-30)

This is a draft.

1.2 Installation Preparations

This section describes the preparations for installation. Before starting the installation, you

must get the installation environment ready, obtain the required reference documents, tools,

and instruments, and familiarize yourself with the skills required.

1.2.1 Installation Environment

Before starting the installation, ensure that the power supply equipment, transmission

equipment, and related matching equipment are ready.

Precautions for Site Selection

lDo not install a RRU3931E near an interference source, such as a broadcast and

television tower, high and low-voltage substation, high-voltage tower, high-power radio

transmitter, and radar station.

lFor the sake of surge protection, the mounting height of a RRU3931E should not be

greater than 10 m. Do not install a RRU3931E along a highway or railway or on the

mountain top, tower, standalone pole in a suburban area or open field, or standalone

rooftop in a non-urban area.

Requirements for the Upper-level Circuit Breaker

Slow-blow fuses of the gL (DIN VDE)/gG (IEC) class in accordance with IEC60269-1 are

recommended. Fuses of the same specifications must be configured for L and N wires for the

sake of O&M security.

Type C bipolar circuit breakers in accordance with IEC60934 are recommended. Circuit

breakers must be configured for L and N wires for the sake of O&M security.

Table 1-1 describes the recommended specifications.

Table 1-1 Requirements on the upper-level circuit breakers and power cables

NOTE

lThe requirements provided in the preceding table are based on the peak power of a RRU3931E and

do not represent power consumption when the RRU3931E is running.

lMinimum value: Ensures that a RRU3931E can work normally under normal circumstances.

However, lightning strikes or abnormal voltage fluctuations may trip the circuit breaker or melt the

fuse.

lRecommended value: Ensures that a RRU3931E can work normally under normal circumstances

and that the circuit breaker does not trip in the event of lightning strikes or abnormal voltage

fluctuations.

lMaximum value: Indicates the maximum rated current allowed in the product design.

Requirements for Surge Protection and Grounding

Huawei by default uses a three-core power cable to connect a RRU3931E and external power

supply equipment. The power supply side must ensure that the PE wire of the three-core

power cable can be properly grounded. In outdoor installation scenarios or outdoor cabling

scenarios, PGND cables must be used to guarantee the surge protection and grounding for the

ground terminals of the mounting kits.

Requirements for power supply

During installation, power off the RRU3931E.

1.2.2 Reference Documents

This section describes reference documents required for installation.

Before starting the installation, you must be familiar with the following reference documents:

lSafety Information

lRRU3931E Hardware Description

1.2.4 Skills and Requirements for Installation Personnel

Installation personnel must be qualified, trained, and familiar with correct operation methods

and safety precautions before performing any operations.

Before starting the installation, pay attention to the following items:

lThe customer's technical engineers must be trained by Huawei and be familiar with the

proper installation and engineering methods.

lThe number of required installation personnel depends on the engineering schedule and

installation environment. Generally, three to five installation personnel are necessary.
