PDU8000 Modular Integrated PDC V1.0

Quick Guide

1Installing the PDC

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

install expansion sleeves.

Securing the PDC

1.1

Leveling foot Level

3. Partially drive the bolts into the expansion sleeves and use a socket wrench to tighten the bolts

in diagonal order.

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) Installing the Tail Frame

1.2

3. Open the cabinet rear door, and remove the rear

door, hinges, ground cable and the connecting kits.

2. Use four M5 tapping screws to secure one

upper sealing plate to the tail frame.

1. Use eight M5 tapping screws to secure the tail

frame accessories to the tail frame.

4. Move the tail frame to the PDC rear door,

and secure it to the PDC using eight M5

tapping screws.

There are two upper sealing plates, and the

one used in this step has a gap.

Put aside the fittings as they are needed in follow-up

installation processes.

1.3 (Optional) Combining Cabinets

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.

2Connecting Cables

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

before connecting cables.

2. Bundle the N and PE cables separately from the L1/L2/L3 or L cables for each circuit breaker

when routing cables. Converge them at the beam and bind each group of them by cable ties.

Ensure that each group has not more than 15 cables.

3. Connect cables from the PDC to the power distribution bars based on terminal specifications in

the following table.

5. Install the cabinet rear door and accessories at the corresponding positions on the tail frame.

Verify that ground cables are properly connected to the cabinet and cabinet rear door.

NOTE

This figure shows how to connect cables for dual inputs. For details about how to connect cables

for a single input, see the procedure for connecting cables for dual inputs.

When cables are routed in from the top, first connect the IT power distribution input cable and

the power distribution input cable of the air conditioner.

When cables are routed in from the bottom, first connect the power distribution input cable of

the air conditioner and the IT power distribution input cable.

It is recommended that you connect cables from left to right when connecting IT and air

conditioner power distribution inputs.

(1) Connect the power cables of the IT equipment

to the terminals of IT output in the PDC.

4. Connect the output cables for the PDC. (2) Connect the power cables of the air

conditioner to the terminals of air conditioner

output in the PDC.

(3) Connect the lighting power cables to the lighting output in the PDC.

Connect the lighting cables to XT2-1–

XT2-6.

In the MCCB dual-input scenario for

the air conditioner power distribution,

the L wire of the lighting cable is

routed on the right side of the cabinet

rear door, and the N and PE wires of

XT2-4–XT2-6 are routed along the

cabling beam in the middle of the PDC

to the N and PE bars on the left side.

5. Connecting Signal Cables for the PDC.

When the MODBUS TCP protocol is used,

connect one end of the network cable to the FE

port in the PDC, and connect the other end to

the collector.

NOTE

6. Secure the cables to cable-routing board by

using cable ties.

7. (Optional) Cut proper cable inlets and

outlets in the rodent-proof meshes and

install the PDC top panel back. Seal the

cable inlets and outlets using firestop putty.

4Power-On Commissioning

1. Switch on the SPD circuit breaker. If the SPD indicator is green, the SPD is running properly. If

the SPD indicator is red, the SPD is faulty and must be replaced immediately.

2. Switch on the upstream output circuit breakers to power on the PDC. If the power indicator on the

front panel of the PDC lights up, the PDC is powered on properly.

•Click the textbox after the IP address assign, and choose Automatic (DHCP).

•Set Rated frequency and Rated line voltage on the System Param. screen based on the

actual situation and retain default values for other system parameters.

•The user name is admin (preset password: 000001).

NOTE

3. After the MDU screen starts, set the language, time, date, network parameters, and system

parameters by using the Setting Wizard.

4. After the quick settings are complete, if the monitoring page displays abnormal alarms, clear

them.

5. Switch on the input circuit breakers on the front panel of the PDC.

6. Switch on the output circuit breakers in the PDC in sequence to power on the corresponding

devices and check whether the monitoring parameters on the display panel are correct.

7. (Optional) Power off the PDC.

(1) Switch off the output circuit breakers in the PDC.

(2) Switch off the upstream input circuit breakers.
