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.

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:

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.

Wall-mounted Installation
In wall-mounted installation scenarios, note the following:
lThe wall has a capacity of bearing at least four times the weight of the RRU3931E to be
installed without damage.
lExpansion bolts must be torqued to 28 N·m to ensure the bolts work properly without
causing cracks on the wall.
