Mounting to DIN rails
1. Pull down the locking tab of the
base part. Hook the back of the
controller onto the upper part of
DIN rail.
2. Push the controller in the
direction of arrow 2.
3. Push up the locking tab to fasten
the controller onto DIN rail.
-
When connecting controllers after
mounting to DIN rail, push up the
locking tab after doing so.
-
Attaching end plates
When mounting controllers to DIN rails, we recommend to attach side connecting
terminal covers (right and left 1set), then end plates (optional) to the ends of the
rightmost and leftmost controllers.
