BEZEL OPTION

Bezels are used to adapt the 48N Series to an existing panel cutout. In order to replace the 48 Series products, use the one attached to the 48N Series as standard.  When the existing panel is cut according to DIN standard, specify ‘/D’ suffix code.
For a new installation, no bezel is required. Please refer to ‘Mounting Requirement’ and mount the 48N directly.
Ingress protection is invalid when the 48N is mounted with a bezel, or when multiple modules are stacked side by side.
