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.

Preparing Consumables2.3

(Optional) Prepare firestop putty for sealing cable holes after cable connection. The fire retardant

bags are to be purchased by the customer.

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.

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.

(1) M12 bolt

(2) Spring washer

(3) Flat washer

(4) Expansion sleeve

(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

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.

NOTE

5Installing Cables

Cable Layout Rules

5.1

Binding Cables

No.

Binding Rule

Power cables and signal cables are bound separately with a distance above 150 mm.

Both ends of a cable are labeled. Labels are clean and correct, and provide concise and

understandable description.

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.

Each bundle contains no more than 15 cables, and cables are neatly bound.

Extra cables are coiled neatly and easy to find.

Cables on the surface of a large cable bundle are neatly organized without unnecessary

crossover.

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.

Cables are reliably bound along the route, and the binding interval meets the requirements in

following table

Cable ties without sharp burs

Cable ties in the same direction

Not tied at bends

Extra length for easier plug and unplug

Stroking cables

No.

Bending Rule

Cables are not overly bent as over bending may damage the cable cores.

Unless otherwise stipulated, the bending radius should be three times more than the cable

diameter if the installation space is sufficient.

Cables are not tied where they bend, as shown in

following figure.

Cables must be a little longer than the exact cable route length to facilitate plug and unplug,

as shown in

following figure.

Cables should be stroked to eliminate abnormal stress on certain cables, as shown in

following figure

Cable Bending

Cable Layout

No.

Layout Rule

The armoring layers of armored cables are grounded.

Cables are securely connected in the correct phase sequence.

Cables are neatly arranged, and cable insulation layers are intact.

Different types of cables are bound separately.

Connection ports and cabling methods facilitate maintenance, cable routing, and capacity

expansion.

Cable connectors prepared onsite must be normal, secure, reliable, and neat.

Power cables, ground cables, and various signal cables are securely connected. Adapters are

securely plugged or screwed.

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.
