Step 5 (If a leakage test with nitrogen has been performed, skip this step.) Raise the
water pressure in the chilled water pipe to 0.8 MPa. If no leakage occurs after 30
minutes, retain the pressure for 24 hours. The expected result is that the pressure
drop is less than 0.01 MPa and the pipe does not leak. Then, release the pressure
in the pipe.
Step 6 Manually close the chilled water valve.

3.6 Installing Cables

● Connections of all power cables, control cables, and ground cables must comply
with local electrical regulations, and the cable specifications should comply
with local cabling specifications.
● For details about the current in full load, see the NetCol8000-C nameplate.
● Primary power supply: 380–415 V AC, 3 PH, 50/60 Hz. The neutral wire does
not need to be connected.
● Only trained and qualified personnel are allowed to connect cables.
● Before connecting cables, use a voltmeter to measure the input voltage and
ensure that the power supply is disconnected.
● All smart cooling products must be securely grounded before being powered
on.
● Wear insulated gloves and use insulated tools to prevent electric shocks or
short circuits.
● Keep cables away from fans and copper pipes (otherwise, take protective
measures), and connect cables securely.
● When laying out cables, ensure that the power and signal cables are reliably
separated and that the electrical and ELV cables are bound separately.
● Cable colors in this document are for reference only.
