Liquid cooling connection:
The standard delivery of the Vacon NX Liquid-Cooled drive includes hoses on the
cooling element 1.5 m in length and 15 mm in diameter. The hoses are inserted
in 1400-mm UL94V0 approved conduits. Connect the line hose branch to its
counterpart (screw or fast connector) on the of the Vacon Liquid-Cooled drive.
Due to high pressure in the line hose, it is recommended to equip the liquid line
with a shut-off valve, which makes the connection easier. In order to prevent
7
water from spraying in the installation room we also recommend to wrap e.g.
linters around the connection on installing. For more information on the liquid
connection, see Chapter 5.2.2.
When the installation in the enclosure is completed the liquid pump can be
started. See Commissioning of the frequency converter on page 137.
NOTE! Do not switch on the power before ensuring the proper functioning of the
liquid cooling system.
