Preparations
Precautions
Only trained and qualified personnel are allowed to install, operate, and maintain Huawei equipment, and they must
understand basic safety precautions to avoid hazards.
If a Mini-shelter is assembled onsite, the site environment should be equal to or above 0°C.
If the cabinet is scratched during transportation, paint or apply glue to the scratched areas.
Prepare a rainproof cloth to protect the Mini-shelter from rain.
Do not step on the base of the shelter to avoid sand and dust.
Before disassembly, clear the space for arranging components, and lay protection materials to protect the components from
scratches and damages. During disassembly, keep small structures and fixtures such as screws together and use
appropriate screwdrivers to avoid stripping screws.
Requirements for the Mini-shelter location:
A Mini-shelter should be installed in a high place where water can be easily drained. Swales and the areas prone to
pondings are unsuitable for site construction.
The cabinet must comply with installation space requirements for later cabinet maintenance.
Requirements for the Mini-shelter installation direction:
Maintenance personnel must be safe when they maintain at the front door of the Mini-shelter.
The Mini-shelter is not exposed to direct sunlight and stays away from the wind.
When installing a mini-shelter in a residential area, ensure the Mini-shelter doors do not face the residential area.
Requirements for Installation Space

Routing Cables in a Mini-shelter
Requirements for Cable Routing
Routing Cables out from the Cabinet
Requirements for routing commons:
Cables are routed through cable trays at both sides of the rack and cable trays at the rack top.
The bending radii of power cables, ground cables, and signal cables should be greater than or equal to five times the radii o f power
cables, ground cables, and signal cables respectively.
Cables should be routed separately without interference.
Routed cables are close to each other, clear, and free of damage.
Cable ties are bundled neatly to the same direction. Cable ties in the same position should be at the same level.
Routed cables are labeled clearly.
Cables routed along the floor should be protected with protection tubes that comply with NFPA70 standards.
Cables to temperature control equipment are bundled first in the cable beam in the upper right of the Mini -shelter and then routed to
the cabinet.
After routing external cables to the Mini-shelter from the cable holes at the bottom of the Mini-shelter, block the cable holes in the
seal cover using black mud.
Requirements for routing special cables:
For power cables:
–48 V DC power cables are bundled together.
Power cables, transmission cables, and signal cables are routed separately and are at least 30 mm away from each other.
When routing multiple power cables, bundle them.
No joint is found in a new power cable.
For protection ground (PGND) cables:
PGND cables in a base station should be connected to the same ground bar.
PGND cables must not be routed in from above. They must be underground or routed indoors.
Both ends of the external conductor of a coaxial cable and the shield layer of a shielded cable should have good electrical c ontact
with the metal shell of the device they connect to.
PGND cables and signal cable should be bundled separately with a proper distance to avoid interference.
Switches or fuses must not be installed on PGND cables.
All conductive metal in the metal shell are connected to protection ground terminals properly.
When the cabinet door is connected to the ground screws at the cabinet bottom using a ground cable, the OT terminal on the
cabinet door should face upwards, the OT terminal at the cabinet bottom should face inwards.
Route external cables into the cabinet through the cable holes at the
cabinet bottom.
1. Remove the seal cover from the bottom.
2. Cut a hole in the seal cover along the lines using a knife or a pair
of scissors based on the cross-sectional area of the cable.
3. Plug the cable hole using the processed seal cover. The cable can
be routed through the hole in the seal cover.

Installing PGND Cables
Principles for connecting ground cables:
1. An indoor ground bar should be installed in the cabinet and near the ACDB or power system (when no ACDB is
configured). All ground cables are routed straightly and bound neatly.
2. Ground screws in the cabinet are hexagonal head screws, so cables should be secured using tools such as an
adjustable wrench, a solid wrench, a socket wrench to ensure proper grounding.

Cable Label Handwriting Description
Fonts:
To make fonts easy to read and look aesthetic, comply with standard font templates (Chinese font) requirements
when writing labels onsite. International users can decide fonts based on actual conditions. The font size and
number of letters are decided based on actual conditions. The standard font template is as described in the
following table. When filling only Chinese characters, choose fonts of proper size to make your hardwiring readable
and aesthetic.
Handwriting direction:
(1) The handwriting direction of characters on the power cable label is the same as the direction of "TO: ", as
shown in the following figure.

Pen:
To make fonts easy to read and look aesthetic, use dedicated black grease pens for handwriting. You can purchase
black grease pens (excluding ballpoint pens) based on actual conditions, for example, there is a shortage of
dedicated pens or the dedicated pencils are missing. In special conditions, you can use black ballpoint pens.
However, you are not recommended to use them because handwriting with ballpoint pens is hard to read.
(2) The direction of characters on the signal cable label is as follows:
