2 PDC Installation
3
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.

4
(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.

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.
