How to Avoid Electromagnetic Interference
Original instructions
About us
Overview
Electromagnetic perturbations may cause the application to operate in an unexpected manner.
WARNING
UNEXPECTED EQUIPMENT OPERATION
In a highly disturbed electromagnetic environment,
  • use the BMXXSP•••• shielding connection kit to connect the shielding and
  • use a stabilised 24 Vdc supply for inputs and a shielded cable for connecting the supply to the module.
  • use a shielded cable for capture inputs and reflex outputs if any of them is wired.
  • use a shielded cable for each SSI channel respectively and note that 24 Vdc and GND must be included in the shielded cable. (Each shielded cable includes CLK pair, DATA pair, 24Vdco, 0Vdco. If the reflex output is connected to encoder, it also has to be included.)
Failure to follow these instructions can result in death, serious injury, or equipment damage.
The figure below shows the recommended circuit for a high-noise environment using the shielding connection kit:
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. Improper fuse selection could result to damage to the module.
Failure to follow these instructions can result in injury or equipment damage.
