EX-FACTORY SETTING

/SET: Preset according to the Ordering Information Sheet

(No. ESU-9437)

BEZEL OPTION

Bezels are used to adapt the 48N Series to an existing panel

cutout. In order to replace M-System’s 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.
