Four LEDs located at the front panel indicate the status of the device. The LEDs assist
maintenance personnel in quickly identifying wiring or communication errors.
A LED test is exercised at power-up, cycling each LED off, green and then red for
approximately 0.25 seconds. At the same time the power-on self test of the device is
performed.

DIN rail mounting and removal
The MBRG-300 gateway is designed to be mounted on a 35 mm DIN rail according to
DIN/EN 50022. The enclosure features a 35 mm profile at the back which snaps into the
DIN rail. No tools are required for mounting. Please observe the rules outlined in the
section called “Mounting rules”.
To mount the unit on a DIN rail, slot the top part of the
MBRG-300 into the upper guide of the rail and lower the
enclosure until the bottom of the red hook clicks into
place.
Mounting rules
The enclosure provides protection against solid objects according to IP20 / NEMAType1
protection rating. When mounting the unit observe the following rules:
• No water splash and water drops
• No aggressive gas, steam or liquids
To remove the MBRG-300 from the DIN rail, use a screw
driver as a lever by inserting it in the small slot of the red
hook and push the red hook downwards. Then remove the
unit from the rail by raising the bottom front edge of the
enclosure.
