2PDC Installation
4
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.

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.

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.

Hardware Installation Checklist
4.1

11
1. Check cable connections and the
mechanical performance.
①Check that cables are connected correctly outside
the cabinet. Check that all bolts are secured for inlet
and outlet cables and tighten a bolt if it is loose.
②Check that ground cables are properly connected.
2. Check the insulation only after the upstream and
downstream circuit breakers in the PDC are
switched off.
①Switch off the upstream circuit breaker QFS for the SPD in the input module of the PDC,
and switch on other circuit breakers.
②Check that the insulation resistance between the live wires, between the live wire and the
PE, and between the live line and the neutral wire is no less than 0.5 megohm using a
multimeter.
③After checking, turn off all the circuit breakers.
3. Switch on the SPD circuit breaker.
4. Switch on the input power
circuit breaker to power on
the PDC. If the power
indicator on the front panel
of the PDC lights up, the
PDC is powered on properly.
If the indicator of an SPD
module is green, the SPD
module is running properly. If
an indicator is red, the
corresponding SPD module has
failed and must be promptly
replaced.
The input power circuit breaker refers to the output circuit breaker that controls power supply
from the upstream power distribution equipment to the PDC.
5Power-On Commissioning
1. The power-on commissioning personnel must be at least two qualified electricians. One
performs operations while the other monitors the operations. Irrelevant persons should be
warned off.
2. User types are classified into admin and operator. User admin has higher operation rights
than user operator.
3. Powering off the PDC disconnects the power supply to the downstream devices. Exercise
caution with this operation when the PDC is supplying power to a working system.

12
5. After the MDU screen starts, log in to the system as the admin or operator user (the
preset password is 000001 for both types of users), and perform the following operations
by referring to the figures:
•If this is the initial startup, set the language, time, date, network parameters, and system
parameters by using the Setting Wizard.
•If this is not the initial startup and these parameters have been set before, the system uses
the existing settings by default.
The figures are for reference only.
The actual parameter values prevail.
6. After the quick settings are complete, if the monitoring page displays alarms, clear the
alarms.
7. Turn on the PDC input switches.
8. Switch on the output circuit breakers except reserved circuit breakers in the PDC in sequence
to power on the corresponding devices and check whether the monitoring parameters on
the MDU screen are correct.
9. (Optional) Power off the PDC.
①Turn off the output circuit breakers in the PDC.
②Turn off the input circuit breakers in the PDC.
③Turn off the input power circuit breaker of the PDC.
For system security purposes, change the preset password upon first login.

BConnecting the Fire Linkage Cables
Scenario 1: single-input or dual-input PDC; one pair of fire control input
cables control all loads to power off.
Single-input PDC: Connect the positive and negative terminals of the fire control cable to the
24VDC(+) and 24VDC(-) wiring terminals at the rear right of the cabinet respectively.
Dual-input PDC: Connect the positive and negative terminals of the fire control cable to the
24VDC(+) and 24VDC(-) wiring terminals at the rear left or rear right of the cabinet respectively.

15
Scenario 2: dual-input PDC; either of the two pairs of fire control input
cables can control all loads to power off.
Separate the two routes of fire control cables and connect them to the fire control signal
wiring terminals on both sides at the cabinet rear. Connect the positive and negative terminals of
each pair of control cables to the 24VDC(+) and 24VDC(-) wiring terminals at the rear left and rear
right of the cabinet respectively.
1. 24 V DC cables routed into the PDC should be shielded cables.
2. Ensure that the polarities of 24 V DC cables routed into the PDC are correct.
