5. INSTALLATION
5.1 Mounting
The NXL drive can be mounted on the wall or on the back plane of a cubicle. There are two
possible positions in the wall mounting for the frames MF2 and MF3 (see Figure 5-1)
The NXL type MF2 is mounted with two screws using the middle holes of the mounting plates. If an
RFI filter is used, the upper mounting plate shall be attached with two screws. MF3 and bigger types
are always mounted with four screws, see Figure 5-2 and Figure 5-3.
Enough space shall be reserved above and underneath the frequency converter in order to ensure a
sufficient cooling, see Figure 5-7, and Table 5-4. Also see to that the mounting plane is relatively
even.
Below you will find the dimensions of Vacon NXL frequency converters with IP20 and IP21
enclosures on pages 20 -- 22.
