IP21/NEMA 1 UPGRADE KIT
An IP21/NEMA 1 upgrade kit is available for the IP20
®
versions of the VLT Advanced Harmonic Filter AHF
005/AHF 010. See chapter 5.3.1 IP21/NEMA 1 Upgrade Kit
for further details.

4.1.4.2 Requirements for IP00

NOTICE
IP00 - FORCED AIR REQURIED
When mounting IP00 versions, pay attention to the
specific requirements for cooling and ventilation. Ensure
that the minimum required forced air speed and air
volume are observed as part of the installation of IP00
versions in panels. See Table 4.2 and Table 4.3 for details.
The IP00 versions do not have integrated fans and
ventilation channels. Thus, it is important that the airflow
passes through the filter to avoid that the filter and other
components in the cabinet overheat. When installing a
filter in deep and/or wide enclosures, there is a high risk
that the air bypasses the filter and therefore does not
provide the required cooling. To control the airflow in
wide/deep cabinets, mount air baffles at the top and at
the bottom. See Illustration 4.11 and Illustration 4.12.
Wrong installations - air bypassing the filter
Illustration 4.8 and Illustration 4.9 show a filter installed in a
deep/wide cabinet without air baffles to control the
airflow. The illustrations show that part of the airflow
bypasses the filter, which results in an overheated filter.
