Electromagnetic Protection
Electromagnetic perturbations may cause unintended equipment operation.
WARNING
UNINTENDED EQUIPMENT OPERATION
In a highly disturbed electromagnetic environment:
  • Use the BMXXSP••00 shielding connection kit to connect the shielding of each cable.
  • Use a stabilized and dedicated 24 Vdc power supply and a shielded cable for connecting the supply to the module.
  • Use shielded cables for inputs and outputs if any of them are wired.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
NOTE: For more detailed information about BMXXSP••00 shielding connection kit, refer to Modicon X80 Racks and Power Supplies, Hardware, Reference Manual.
The figure below shows the recommended circuit for a high-noise environment using the BMXXSP••00 shielding connection kit:
Improper fuse selection could result to damage to the module.
CAUTION
POTENTIAL MODULE DAMAGE - IMPROPER FUSE SELECTION
Use fast acting fuses to protect the electronic components of the module from overcurrent and reverse polarity of the input/output supplies.
Failure to follow these instructions can result in injury or equipment damage.
