5. INSTALLATION
5.1 Mounting
The frequency converter can be mounted in either vertical or horizontal position on the wall or on the back
plane of a cubicle. However, if the drive is mounted in a horizontal position, it is not protected against
vertically falling drops of water.
Enough space shall be reserved around the frequency converter in order to ensure a sufficient cooling, see
Figure 5-11, Table 5-10 and Table 5-11. Also see to that the mounting plane is relatively even.
The frequency converter shall be fixed with four screws (or bolts, depending on the unit size). The
dimensions of installation are presented in Figure 5-11 and Table 5-10.
Lift units bigger than FR7 out of the package using a jib crane. Ask the factory or your local distributor for
information on how to lift the unit safely.
Below you will find the dimensions of both wall-mounted as well as flange-mounted Vacon NX frequency
converters. The dimensions of the opening needed in flange mounting are given in Table 5-3 and Table 5-5.
The sizes FR10 to FR12 are floorstanding units. The enclosures are equipped with fixing holes. For dimen-
sions see below.
