3-3-1 Installation in a Control Panel
Use the following installation procedure.
1 Open a hole in which to embed the NA Unit with the following dimensions and insert the NA Unit
from the front side of the panel.
2 To conform to UL Type 4X standards, the panel thickness must be between 1.6 and 4.5 mm.
Always use the NA5-W with a High-pressure Waterproof Attachment (PWA) in
applications requiring UL Type 4X level protection. This is mandatory because there is a risk of
water entry, which may cause severe equipment damage.
Make sure that the internal dimensions at the back of the PWA allow mounting.
Slide the PWA over the NA Unit from the back until the flat side of the PWA is flat against the inside of
the panel, as shown in the following figure.
