Installing the Mounting Bracket
3.2
⚫To prevent dust inhalation or contact with
eyes, wear safety goggles and an anti-dust
mask when drilling holes.
⚫Clean up any dust in and around the holes
using a vacuum cleaner and measure the
hole distances. If the holes are inaccurately
positioned, drill holes again.
⚫Level the head of the expansion sleeve
with the concrete wall after removing the
bolt, spring washer, and flat washer.
Otherwise, the mounting bracket will not be
securely installed on the concrete wall.
Avoid drilling holes in the water pipes and power cables buried in the wall.
Wall-mountedInstallation
The mounting bracket has four groups of tapped holes, each group containing four tapped holes.
Mark any hole in each group based on site requirements and mark four holes in total. Two round
holes are preferred.
1. Mark hole positions.
3Installing the Cabinet
InstallationSpace
Preparations
3.1
Bolts
•When the cabinet is installed on a wall, you
need to prepare M12 x 60 stainless steel
exploded expansion bolts.
•If the cabinet is installed on a support or a
pole, use the M12 x 40 bolt assemblies
delivered with the cabinet.

11
3. Secure the mounting bracket.
1. Mark hole
positions.
2. Install expansion bolts.
⚫If you need to pole-mount the smart array controller, prepare a pole mounting bracket based
on the dimensions of the smart array controller. You are advised to use M12 U-shaped bolts to
secure the pole mounting bracket.
⚫The figure is for reference only. The actual pole and pole mounting bracket prevail.
Pole-mountedInstallation
1. Secure the pole mounting bracket.
2. Drill holes. (You are advised to
apply anti-rust paint on the
hole positions for protection.)
3. Secure the
mounting bracket.
Support-mountedInstallation
2. Secure the mounting bracket.

12
1. Loosen the screws on the main
cabinet door. 2. Open the main cabinet door and install the support bar.
4Opening the Main Cabinet Door
⚫Before opening the main cabinet door, turn off all upstream switches for the smart array
controller to power off the smart array controller. If you have to operate an energized smart
array controller, wear insulation gloves and take preventive measures.
⚫If you need to open the main cabinet door on rainy or snowy days, take protective measures to
prevent rain or snow fromentering the cabinet. If it is impossible to take protective measures,
do not open the main cabinet door on rainy or snowy days.
Securing the Cabinet
3.3
1. Install the cabinet on the mounting bracket. 2. Remove the security torx wrench bound to
the cabinet base and use the wrench to
tighten security torx screws.
5Installing Components
Install components based on chapter 2 "Configurations in Typical Scenarios."

13
1. Loosen screws and remove the mounting board. Do not remove the screws.
2. Remove screws from the POE module installation position.

⚫To prevent poor cable connection due to overstress caused by ground subsidence, it is
recommended that the cable be bent and reserved 20–30 mm (0.79–1.18 in.) inside the cabinet
and then connected to the appropriate port.
⚫If a cable has a jacket, ensure that the jacket is in the cabinet.
⚫The following describes how to connect a peripheral cable to the RS485/ETH/DC waterproof
connector in common mode and through a tube, and provides reference for connecting
peripheral cables to other waterproof connectors.
Common Connection
1. Remove the locking cap and plug from
the waterproof connector.
2. Route the cable through the locking
cap and then the waterproof connector.
3. Connect the cable.
4. Tighten the locking cap.
5. Check that the cable is connected
correctly and securely. Seal the
waterproof connector and cable hole
using the supplied firestop putty.
6. Clear foreign matter from the cabinet.
If you choose common connection, ensure
that the appropriate cable is available.
Nut Conduit
Fitting
If you choose connection through a tube, ensure that the appropriate cable and tube are available.
Prepare appropriate tubes based on the diameters of bottom cable holes. It is recommended that
the tube specifications comply with the waterproof connector specifications. For example, for a 3/4
in. waterproof connector, a 3/4 in. tube is recommended.

Diameters of bottom cable holesTube
6Connecting Cables
Connect cables in accordance with the installation laws and regulations of the country or region
where the project is located.
Selecting a Connection Method
6.1
You can connect a peripheral cable to the smart array controller in common mode or through a
tube based on site requirements.

15
1. Remove the locking cap and plug from
the waterproof connector, and then
remove the waterproof connector.
2. Secure the tube fitting using the nut
delivered with the tube.
3. Route the cable through the tube
conduit and then fitting.
4. Connect the cable.
5. Secure the fitting to the conduit.
6. Check that the cable is connected
correctly and securely. Then take
appropriate measures to ensure that
the tube conduit and fitting are secured
reliably, and seal the cable hole using
supplied firestop putty.
7. Clear foreign matter from the cabinet.
Crimping an OT Terminal
6.3
⚫Avoid scratching the core
wire when stripping a cable.
⚫The cavity formed after the
conductor crimp strip of the
OT terminal is crimped must
wrap the core wires
completely. The core wires
must contact the OT
terminal closely.
⚫Wrap the wire crimping area
with heat shrink tubing or
PVC insulation tape. The
right figure uses heat shrink
tubing as an example.
⚫When using the heat gun,
protect devices from being
scorched.

You can connect a peripheral cable to the smart array controller in common mode or through a tube.
⚫The way of handling the bottom waterproofconnector varies depending on the connection
method. For details, see section 6.1 "Selecting a Connection Method."
⚫Cables to the cabinet interior are connected in the same way irrespective of which connection
method is used. The following uses common connection as an example.
Preparing Cables
Before connecting cables, prepare appropriate cables by referring to chapter 2 "Configurations in
Typical Scenarios."
