9.4 Mounting to DIN rail
Caution
Mount the DIN rail horizontally.
When DIN rail is mounted vertically, be sure to use commercially available fastening plates at the end of
DCL-33A. Mount the DCL-33A to the DIN rail so that the DCL-33A cannot move.
However, if the DIN rail is mounted horizontally in a position susceptible to vibration or shock, the fastening
plates must be used as well.
