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).

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.
