Concrete Platform Scenario
3.1
3Securing the FusionCol8000-E
1. Read the related user manual before installing the device.
2. Ensure that the concrete platform levelness meets the requirements before installation.
3. It is recommended that the strength of the concrete foundations be at least C20 and
the load-bearing capacity of the ground be greater than or equal to 500 kg/m2.
1. Determine the location of concrete platforms according to the site space and equipment
dimensions. Mark the reference points of concrete platforms using an ink fountain and
measuring tape.
•When marking the mounting positions for concrete platforms, ensure that the four lines form
a rectangle.
•When the equipment is installed indoors, it is recommended that shock pads be installed.
•It is recommended that the strength level of the concrete foundation be C20 or higher.

Method 2: Installing a Ground Cable
4Connecting Water Pipes
1. Install water pipes.
(1) Condensate drainpipe (DN25)
(2) Spray drainpipe (DN40)
(3) Spray water refill pipe (DN20)
•When installing the water seal,
keep it horizontal and allow a
maximum downward inclination of
5°.
•Install the water seal in strict
accordance with the figure to avoid
reverse connection.
Ground cables can be
routed through plastic-
coated metal hoses for
protection based on site
requirements.
1. The water pipes are connected using thread connectors. The threaded joints must be sealed
with sealing tape or thread adhesive.
2. Clean the external water pipes before connecting them to the water inlet and outlet pipes.
3. Connect the water inlet and outlet pipes of the FusionCol8000-E using thread connectors.
When connecting the water pipes, do not exert excessive force to prevent damage to the
pipes. (When connecting the pipes, use two pipe wrenches or chain pliers.)
4. At low temperatures, take thermal insulation measures to prevent water pipes from
freezing.
5. Water pipes must be wrapped with thermal insulation foam (including the buried pipes).

7
Sealing putty
Paper protective film
2. Remove the paper protective film from the sealing putty.
3. Seal the gap between the water pipe and the equipment using sealing putty after the pipe
is correctly connected.
4. Condensate drainpipes and water refill pipes may freeze and thereby be blocked or crack in
low-temperature areas. Anti-freezing measures must be taken for the pipes.
(1) Water seal
(2) Electric heating belt
(3) Water refill pipe
(4) Drainpipe (The end needs to be
connected to the utility drainpipes.)
(5) Soil
5. Wrap the electric heating belt (distance ≥ 27 mm) before wrapping the thermal insulation
foam. The thermal insulation foam must be able to withstand a temperature higher than
200°C.

6Connecting Cables
1. All power cables and ground cables must
comply with local national standards.
2. After connecting power cables and checking
cable connections, use sealing putty to fill in
the gap between the cables and the cabinet
(as shown in the right figure), and the sealing
putty can be obtained from the fitting bag.
(1) Paper protective film (2) Sealing putty (mandatory)

terminals X502 and X504.
•If a water sensor (rope-type) is connected to the outside,
connect the signal cable to terminals X201 and X202.
Connecting Power Cables
In side cabling mode, remove baffle plates 1 and 2 in front of the cable holes, install the protective coil on baffle plate 1, install
baffle plate 1 to the original position, and then route the power cables through the protective coil and cable holes in sequence.

1. Connect the IN port on the first T/H sensor outside the cabinet to the RS485/12V port on the
main control board.
2. Connect the OUT port on the T/H sensor outside the cabinet to the IN port on the next T/H
sensor outside the cabinet in series.
3. Set the DIP switches on the T/H sensors.
Each smart cooling product supports a
maximum of twelve T/H sensors outside the
cabinet, including a maximum of six cold aisle
T/H sensors and six hot aisle T/H sensors.
(1) RS485/12 V port on the main
control board
(2) Connecting to a T/H sensor
outside the cabinet
The T/H sensors outside the cabinet are used to detect the long-distance temperature and
humidity. They can be flexibly installed based on the onsite situation. It is recommended that
the sensors be deployed near heat sources, or near places that lack cooling air. Place the T/H
sensors outside the cabinet near the cabinet and do not directly face them to the air exhaust
vent of the equipment.
