3Installing the Equipment
1. Read the NetCol5000-C(030, 032, 065) In-row Chilled Water Smart Cooling Product User
Manual (2019) or instructions before installing the NetCol5000-C.
2. You are recommended to use tools that are fully insulated when installing devices.
3. Only engineers from the manufacturer or engineers certified by the agent are allowed to
install, commission, and maintain smart cooling products. Otherwise, personal injuries and
device damage may be caused, which is beyond the smart cooling product warranty range.

Removing Air Filters
3.1 Discharging Nitrogen 3.2
Slowly open the exhaust valve to release nitrogen and
close the valve afterwards.
1. The equipment has been injected with 0.2–0.6 MPa
of nitrogen before delivery. If no nitrogen is
discharged, contact Huawei technical support.
2. You can open or close the exhaust valve using a flat-
head screwdriver.
Removing the Pallet

2. Keep a clearance of at least 25 mm between pipes. Secure the pipes to supports every a
certain distance.
3. Clean the water inlet engineering pipes to avoid impurities entering into the humidifier.
4. A reducing valve must be installed if the inlet water pressure exceeds 0.7 MPa.
5. Pipes should be wrapped with thermal insulation foam along the route.

(Optional) Leakage Test with Nitrogen
4.5
•If the pressure has fallen, apply soapy water on the pipes, especially pipe joints, to check for
leakages. Rectify the leakages if any.
•If the pressure is stable, wrap all pipes and connectors with thermal insulation foam.
•Install a reducing valve on the outlet of the nitrogen cylinder. Its outlet pressure must not
exceed 0.8 MPa.
•In addition to the leakage test with nitrogen, there is the leakage test with water. You can
choose one test based on site requirements.
1. Rotate the chilled water valve to the
maximum (100%).
2. Check that the needle and exhaust valves
on the pipeline are closed.
3. Connect a reducing valve and a nitrogen
cylinder at the needle valve position
shown in the figure, charge 0.8 MPa of
nitrogen (when the pressure is stable),
and leave them for 24 hours.
4. Check for pressure change after 24 hours.
Injecting Water to Expel Nitrogen
4.7
Clean the main pipe beforehand to avoid blockage of the
heat exchanger due to foreign construction matter. Close
the isolation valve on the water inlet and outlet pipes
before the cleaning.
1. Open the general water supply valve.
2. Press the button on the side of the actuator and
manually rotate the valve handle to the maximum in
the specified direction. Check that the chilled water
valve is in the open state (100%).
3. Slowly open the exhaust valve to let out gas.
4. Adjust the gas releasing speed until no gas flows out
of the valve. Then close the exhaust valve.
5. Manually close the chilled water valve.
(Optional) Leakage Test with Water
4.6
Manually open the chilled water valve. Inject water to 0.8 MPa,
and preserve the pressure for 24 hours. Then connect a pressure
gauge to a needle valve on the pipeline to measure the
pressure. If the reading remains unchanged, the pipe is not
leaking. You can perform the following operations.
If the leakage test has been
done with nitrogen, skip the
test with water.

5Installing Cables
Connecting the Equipotential Ground Cable and Power Cable
5.1
1. When routing the cables, wrap the section of all signal cables inside the smart cooling
product with the corrugated pipes and route them out of the corresponding cable holes so
that the strong- and weak-current cables are separated.
2. Route the power cable along the rear door post, and use cable ties to secure the cable to the
post every 150–200 mm.
1. Connect the equipotential cable. 2. Connect the power cable.
(Optional) Connecting the Water
Sensor
5.2
1. Connect the temperature and humidity
(T/H) sensor cable.
T/H sensors in the aisle should be installed
at the door frame inside the server cabinet
and 1.5 m above the ground (33 U). After
they are secured, set the sensor positions
based on their location and the table.

•A maximum of 32 smart cooling products can be networked in one group. The teamwork
cable between two adjacent smart cooling products must not exceed 10 m.
•If CAN networking is required onsite, set Enable teamwork CAN resistor for the first and last
smart cooling products to Yes on the screen.
Connect one end of the FE network cable to the
FE port on the main control module, connect the
other end to the POE port on the smart ETH
gateway.
CAN teamwork networking cable
1. Prepare the 8 pin standard network cable, the cable pin sequence requirements are shown
below.
2. Connect the CAN_OUT port of each smart cooling product to the CAN_IN port of the following
smart cooling product using a CAN network cable. After powering on the device, set the Enable
teamwork CAN resistor to Yes for the first and last devices in a teamwork group.

Connecting the FE monitoring cable (SNMP/Modbus-TCP protocol)
(Optional) Connecting the Monitoring Network Cable
5.5
The smart cooling product supports both RS485 monitoring and FE monitoring.
The FE monitoring and FE teamwork use the same network cable. Connect the FE monitoring
cable in the same process of connecting the FE teamwork network cable.
RS485 Monitoring Network Cable (Modbus-RTU Protocol)
1. Make the COM network cable by referring to the following figure.
•If there is no teamwork control, connect the COM_IN port on each smart cooling product to
the customer's monitoring system.
2. Group smart cooling products for monitoring based on performance requirements and
connect the monitoring network cables.
•In CAN networking, connect the COM_IN port on the first smart cooling product in each
monitoring group to the monitoring device.
