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
SCZ10. Mount the SCZ10 to the DIN rail so that the SCZ10 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.
