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.
