INSTALLATION

5.1 Mounting
Vacon NX Liquid-Cooled Drive modules must be installed into an enclosure. The drives consisting of one
module will be mounted on the mounting plate. The drives that include two or three modules are mounted
inside a mounting bracket (see) which will then be installed in the enclosure.
Note: If any other than vertical installation position is required, please contact your distributor!
In chapter 5.1.2 you will find the dimensions of Vacon NX Liquid-Cooled drives installed on mounting bases
(plates and brackets).
5.1.1 Lifting the drive
We recommend you to always use a jib crane or similar elevating device to lift the frequency converter/ in-
verter unit. See figures below for correct lifting points.
For units with no mounting bracket (see chapter 5.1.2.2), the best place for hoisting is the hole(s) in the
middle of the mounting plate (Lifting point 1). Vacon NX Liquid-Cooled drives consisting of several modules
can the most safely and easily be lifted by the holes in the mounting bracket (Lifting point 2) using a screw
pin shackle. Pay also attention to the recommended dimensions of the hoisting belt and the beam. See
Figure 5-1.

In cabinet installation, the hoisting procedure described above right may, however, become difficult or even
impossible if the cabinet width does not allow the use of the screw pin shackle in Lifting point 2 (see
above).
In such case, follow the lifting procedure described in Figure 5-2. The mounting becomes easier and safer
if the drive can be laid on a
aligning stud
to guarantee an easy and safe mounting.
