4.3 Fixation by DIN RAIL
In an environment with slight vibration (less than 0.5G), this is the most convenient way of fixation and is easy for
maintenance. Please use DIN EN50022 DIN RAIL, as shown in the figure below.
Mount 以 Hold PLC facing its front, press it down with a 15 degree tilt onto the DIN RAIL. Swing it down until the
upper edge of DIN RAIL groove on PLC back touches the upper tab of DIN RAIL. Then use this
locked-in point as a pivot to press the PLC forward on the bottom and lock it in position. The procedure
is illustrated below:

position to remove PLC, as shown in the figure below.
