2Installation Preparations
1. This document describes the process for installing the modular precision power distribution
cabinet (PDC). Before installation, read PDU8000 Modular Precision PDC User Manual (1100
mm Deep) to learn the product information and safety precautions.
2. Use insulated tools during installation and operation.
3. Only engineers certified by the manufacturer or its agents are allowed to perform PDU8000
installation, commissioning, and maintenance. Otherwise, personal injury or equipment
damage may occur, and the resulting PDU8000 faults are beyond the warranty scope.
4. Sections and steps marked as optional in this document can be performed selectively based
on the actual configuration.

3Acceptance Guide
1. Check whether the tiltwatch indicator on the carton has turned red. If yes, record the information
and contact the equipment carrier and the local Huawei office immediately.
2. Visually inspect the equipment appearance to check whether the equipment is paint-peeling,
misshapen, scratched, or soaked. If yes, record the information and contact the equipment
carrier and the local Huawei office immediately.
3. Check against the packing list that the equipment and fittings are correct and complete. If some
fittings are missing or do not comply with the models in the packing list, record the information
and contact the local Huawei office immediately.
Unpacking and Accepting Goods
3.1
1. If any damage is found, report it to the carrier immediately.
2. After the equipment is delivered to the installation site, representatives from the customer and
Huawei unpack and inspect the equipment together.
3. Move the cabinet with caution to avoid bumping or toppling. To prevent damaging the
equipment, exercise caution when removing the packing materials.
Unpacking
3.2
1. Move the PDC to the specified installation position using a forklift.
2. Cut off and remove the binding straps.
3. Remove the packing materials and foam.
4. Remove the plastic bag, take out the fitting box, and put it away.
NOTE
4Installing the PDC
Transporting the PDC
4.1
1. The PDC weighs about 350 kg. Take protective measures during movement to prevent toppling
and bumping.
2. Avoid squeezing the MDU screen during the transportation.

6
1. Move the PDC to the specified installation
position using a forklift.
2. Remove the two L-shaped brackets from
the front and rear of the PDC and pallet.
To prevent cabinet tilting and avoid equipment
damage, adjust all the feet instead of one foot.
5. Adjust the PDC leveling feet using
a wrench to ensure that all castors
touch the ground.
6. Arrange four persons to push the
PDC off the wooden pallet to the
ground with caution.
3. Use diagonal pliers to cut off the ties
securing the unloading ramp, and take out
the unloading ramp.
4. Clip the unloading ramp to the wooden
pallet.
Installing the PDC
4.2
Installing the PDC on a Concrete Floor
1. Determine the PDC
installation position.
2. Mark the positions for
installing expansion bolts.
3. Use a hammer drill to drill
holes to depths of 52 mm to
60 mm at the positions for
installing expansion bolts.
Unit: mm
4. Slightly tighten the
expansion bolt and vertically
insert it into the hole. Knock
the expansion bolt using a
rubber mallet until the
expansion sleeve is fully
inserted into the hole.
5. Partially tighten the
expansion bolt.
6. Remove the bolt, flat
washer, and spring washer.

(5) Concrete floor
(1) Level
9. Level the PDC using a level and an
adjustable wrench.
10.Tighten the four M12 bolts.
7. Align the PDC mounting
holes with the expansion
bolt holes.
8. Adjust the anchor bolts of
the PDC using an
adjustable wrench until the
leveling feet touch the floor.
In the cabinet combination scenario, the bolts
need to be pretightened.
NOTE
1. Wrench a leveling foot clockwise to elevate
the cabinet, or wrench a leveling foot
anticlockwise to lower the cabinet. The
leveling feet can be adjusted within a range
of 0–8 mm.
2. To prevent cabinet tilting, adjust all the feet
at the four corners instead of one foot.
3. Do not remove anchor bolts, because this
work brings you only a great deal of
reworking.
NOTE
Installing the PDC on an ESD Floor
1. Lower the leveling feet of the PDC using
an adjustable wrench until all castors are
off the ground.
2. Lift the PDC onto the support and align
the mounting holes on the PDC with
those on the support.
3. Level the PDC by adjusting the leveling
feet, as shown by (1) and (3) in the figure.
4. Insert four M12 bolts into the mounting
holes on the PDC and support, and
tighten the bolts, as shown by (2) in the
figure
(1) Leveling foot
(2) Fixing bolt
(3) Level
In the cabinet combination scenario, the bolts need to be pretightened.
NOTE

8
1. Remove the front and rear
doors of the PDC and level
the PDC, as shown by (1)
in the figure.
2. Remove the cabinet
connecting plates from the
rack, as shown by (2) in
the figure.
3. Secure the connecting
plates in the connection
positions on the front door
using screws, as shown by
(3) in the figure.
4. Use the same method to
secure the connecting
plates in the connection
positions on the rear door.
5. Repeat the preceding
steps to combine other
PDCs.
6. Reinstall the front and rear
doors of the PDC.
7. Use a torque wrench to
tighten the bolts in
diagonal order.
(Optional) Combine cabinets.
4.3
1. A connecting plate is initially secured by one screw. Remove the screw from the column of the
adjacent cabinet to secure the connecting plate.
2. Ensure that both the vertical deviation and the distances between cabinets are within 3 mm after
the cabinets are combined.

5Installing Cables
Cable Layout Rules
5.1
Binding Cables
No.
Binding Rule
1
Power cables and signal cables are bound separately with a distance above 150 mm.
2
Both ends of a cable are labeled. Labels are clean and correct, and provide concise and
understandable description.
3
Cable ties are neatly cut without sharp burs, evenly distributed, bound to a proper strength,
and fastened towards the same direction if possible,
as shown in the following figure.
4
Each bundle contains no more than 15 cables, and cables are neatly bound.
5
Extra cables are coiled neatly and easy to find.
6
Cables on the surface of a large cable bundle are neatly organized without unnecessary
crossover.
7
Cables are arranged in distinct layers and crossovers are avoided if possible when cables in
different colors are bound together,
as shown in the following figure. Cables are arranged by
thickness when arrangement by thickness conflicts with arrangement by color.
8
Cables are reliably bound along the route, and the binding interval meets the requirements in
following table

Not tied at bends
Extra length for easier plug and unplug
Stroking cables
No.
Bending Rule
1
Cables are not overly bent as over bending may damage the cable cores.
2
Unless otherwise stipulated, the bending radius should be three times more than the cable
diameter if the installation space is sufficient.
3
Cables are not tied where they bend, as shown in
following figure.
4
Cables must be a little longer than the exact cable route length to facilitate plug and unplug,
as shown in
following figure.
5
Cables should be stroked to eliminate abnormal stress on certain cables, as shown in
following figure
.
Cable Bending
Cable Layout
No.
Layout Rule
1
The armoring layers of armored cables are grounded.
2
Cables are securely connected in the correct phase sequence.
3
Cables are neatly arranged, and cable insulation layers are intact.
4
Different types of cables are bound separately.
5
Connection ports and cabling methods facilitate maintenance, cable routing, and capacity
expansion.
6
Cable connectors prepared onsite must be normal, secure, reliable, and neat.
7
Power cables, ground cables, and various signal cables are securely connected. Adapters are
securely plugged or screwed.
8
The N and PE cables are bound separately from the L1/L2/L3 or L cables for each circuit
breaker. Cables are converged at the beam and bound in groups by cable ties.
