Installation
Only trained and qualified personnel should install the P224xx P1 loop-powered isolator.
For SIL applications, the 20 mA signal lines must be galvanically isolated from the mains.
Be sure to observe the national codes and regulations during installation and selection of
cables and lines. Make sure that the connecting cables have an appropriate temperature
rating.
Shut-off
Whenever it is likely that the protection has been impaired, the device shall be made
inoperative and secured against unintended operation.
The protection is likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended function
• after prolonged storage at temperatures outside the specified temperature range
• after severe transport stresses
Before recommissioning the device, a professional routine test must be performed.
This test should be carried out at our factory.
