2PDC Installation

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

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.

1100 mm deep cabinet 1200 mm deep cabinet

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) Combining 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.

Scenario 1

Scenario 2

When combining cabinets, ensure that all cabinet

surfaces are at the same level.

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.

3Installing 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.

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

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

1. In single-input scenarios, connect the input N

cable to 1N.

2. Connect the three-phase cables, N cable, and

PE cable in turn.

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.)

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

Connecting Cables (Bottom Cable Routing)

1. Remove the transparent covers of the N

bar and input copper bar, and put the

covers aside.

2. Connect cabinet ground cables.

5. The following figure shows the overall

effect after cable connection.

6. Connect the PDC monitoring cable to the

RS485_1 or FE port on the MDU side panel.

(1) Monitoring cable outlet

7. (Optional) Connect the fire linkage cable

by referring to Appendix B.

8. Reinstall the transparent covers of the

input copper bar and N bar.

9. 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.)
