4.1.4.1 Requirements for IP20 and IP21/
NEMA 1
To guide air through the gap between the wall and the
filter, mount the filters on a wall. In installations, for
example panels, where the filter is mounted on rails, the
filter is not sufficiently cooled because of false airflow. To
overcome the false airflow, order a backplate (thickness:
2 mm (0.08 in)), shown in
. See
for
order number.
For information about the backplate dimensions, see
chapter 7.4.4 Backplate Dimensions
