No shock protection. Danger of electric shock!
‣ If you are modifying or extending your hardware, always fill the slots from top to bottom. Do
not leave any gaps.
‣ If not all the slots are occupied, always insert a dummy or end cover beneath the last module.
This ensures the unit is shock-protected.
‣ Always ensure shock protection is guaranteed particularly in the case of relay modules (2R,
4R, AOR).
