Methods for Mounting and Removal
The RS-232/RS-422 convertor unit (NT-AL001-E) can be mounted on a DIN rail or in an operation panel.
The RS-422A terminal block of the convertor unit can be easily removed.
Mounting to a DIN Rail
Latch the top part of the rear face of the convertor unit (a in the figure) onto the top edge of the DIN rail, and push the
unit in the direction indicated by b in the figure.
Now fit end plates at the right and left of the convertor unit to secure it and ensure that it cannot shift laterally.
