Description
To increase the degree of protection of the cabinet units from IP20 (standard) to IP21,
additional canopies are supplied.
Increasing the degree of protection in this way ensures that not only is the cabinet unit
protected against the ingress of foreign bodies with a diameter of 0.5" (12.5 mm) and above
(IP20, protection level provided as standard), but also against the ingress of water droplets
falling vertically from above (IP21).
The canopy is mounted using spacers at a distance of 10" (250 mm) above the top cover of
the cabinet. The canopy increases the height of a cabinet unit by 10" (250 mm), as shown in
the diagram below (number (1)).
