2 PDC Installation

1. This document describes the process for installing the modular precision power distribution

cabinet (PDC). Before installation, read the User Manual to learn the product information and

safety precautions.

2. When installing or operating a device, you must use insulated tools.

3. Only engineers certified by the manufacturer or its agents are allowed to perform PDC

installation, commissioning, and maintenance. Otherwise, personal injury or equipment

damage may occur, and Huawei will not be liable for any loss.

4. Sections and steps marked as optional in this document can be performed selectively based

on the actual configuration.

NOTICE

1. Due to the limitations of the door height, you can move the device into the equipment room by

tilting it. Keep it upright in the equipment room.

2. Take protective measures during moving the PDC to prevent toppling and bumping.

3. During movement, be careful to avoid squeezing the MDU screen.

Leveling foot Level

1. Mark the positions for installing the PDC based on the marking-off template. Drill holes and install

expansion sleeves.

2. Place a level on the PDC. Adjust the anchor bolts of the PDC using an adjustable wrench until the

leveling feet are in contact with the floor. Then level the PDC.

(Optional) Combine cabinets

2.3

3. Secure the PDC.

(Optional) When the PDC installation environment is 5# channel steel and that the PDC cannot be

secured using the mounting holes, secure the PDC using the mechanical part shown in the

following figure.

NOTE

Scenario 1

Scenario 2

When combining cabinets, ensure that all cabinet

surfaces are at the same level.

NOTE

1. Open the front and rear doors.

Wrench the anchor bolts using

an adjustable wrench to adjust

the cabinet height.

2. Remove the cabinet

connecting kits from the rack.

3. Screw the connecting kits in

the connection positions on

the front door.

4. Use the same method to

secure the connecting kit in

the connection positions on

the rear door.

5. Repeat the preceding steps to

combine other PDCs.

6. Use a torque socket wrench to

tighten the bolts in diagonal

order.

3 Installing Cables

This document uses the dual-input top cable routing and single-input bottom cable routing as

examples. Cable connections for other scenarios are similar.

1. Ensure that all circuit breakers, including upstream output circuit breakers, are switched to OFF

before connecting cables.

2. The PDC ground cable is secured to the equipment room ground bar. The resistance between

the PDC ground cable and the equipment room ground bar is less than 0.1 ohm.

3. 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.

NOTICE

1. Remove the rodent-proof meshes at the top and put them aside.

2. Remove the transparent covers of the N bar

and input copper bar, and put the covers

aside.

3. Connect cabinet ground cables.

4. Connect the input power cables. 5. Connect the output power cables.

Connect the three-phase cables, N cable, and

PE cable in turn.

NOTICE

6. The following figure shows the overall

effect after cable connection.

7. Connect the PDC monitoring cable to the

RS485_1 or FE port on the MDU side panel.

(1) Monitoring cable outlet

8. (Optional) Connect the fire linkage cable by

referring to Appendix B.

9. Cut suitable holes in the rodent-proof

meshes and reinstall the rodent-proof

meshes.

10.Reinstall the transparent covers of the input

copper bar and N bar.

11.Seal the gap between cables and the

cabinet using flake sealing putty. (Remove

the paper protective film from the sealing

putty and use the aluminum foil film together

with the sealing putty.)

4. Connect the input power cables. 5. Connect the output power cables.

Connecting Cables (Bottom Cable Routing)

1. Remove the rodent-proof meshes at the bottom and put them aside.

2. Remove the transparent covers of the N bar

and input copper bar, and put the covers

aside.

3. Connect cabinet ground cables.

6. The following figure shows the overall effect

after cable connection. 7. Connect the PDC monitoring cable to the

RS485_1 or FE port on the MDU side panel.

(1) Monitoring cable outlet

8. (Optional) Connect the fire linkage cable by

referring to Appendix B.

9. Cut suitable holes in the rodent-proof

meshes and reinstall the rodent-proof

meshes.

10.Reinstall the transparent covers of the input

copper bar and N bar.

11.Seal the gap between cables and the

cabinet using flake sealing putty. (Remove

the paper protective film from the sealing

putty and use the aluminum foil film together

with the sealing putty.)
