3.9 Enclosing size 5 to 6 drive for high
environmental protection
An explanation of the environmental protection rating is provided in
section 11.1.9 IP / UL Rating on page 167.
The standard drive is rated to IP20 pollution degree 2 (dry, non-
conductive contamination only). However, it is possible to configure the
size 5 to 6 drive to achieve IP65 rating at the rear of the heatsink for
through-panel mounting (some current derating is required).
Refer to Table 11-3 on page 160.
This allows the front of the size 5 to 6 drive, along with the various
switchgear, to be housed in an IP65 enclosure with the heatsink
protruding through the panel to the external environment. The majority of
the heat generated by the drive is dissipated outside the enclosure,
thereby maintaining a reduced temperature inside the enclosure.
This relies on a good seal being made between the heatsink and the
rear of the enclosure using the gaskets provided.

In order to achieve the high IP rating on the size 5 drive, it is necessary
to seal a heatsink vent by installing the high IP insert as shown in
Figure 3-32.

To seal the space between the drive and the backplate, use the two
securing brackets as shown in Figure 3-30. The securing brackets,
gasket and high IP inserts are included in the through-panel mounting
kit. The part numbers are shown in Table 3-5.
