Caution
Mount the DIN rail horizontally.
When DIN rail is mounted vertically, be sure to use commercially available fastening plates at both ends of
KT7 series. Mount the KT7 series to the DIN rail so that the KT7 series 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.
