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. Enough space shall be reserved around the frequency converter in
order to ensure a sufficient cooling, see Figure 5-6, Table 5-6 and Table 5-7. For safe
installation, ensure that the mounting surface is relatively even.
The frequency converter should be fixed with four screws (or bolts, depending on the unit size).
The dimensions of installation are presented in Figure 5-6 and Table 5-6.
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 are the dimensions of the NX frequency converters with IP21 enclosure in Figure 5-1 and
with IP21 for collar installation in Figure 5-2. The dimensions of the opening needed in collar
installation are given in Table 5-3 and Table 5-5.
