General Safety
 Where personal safety or significant property damage can occur due to a spill, the application must
have a redundant backup safety system installed.
 Wiring should always be done by a licensed electrician.
 Supply voltage should never exceed 28 VDC.
 Protect the sensor from electrical spikes by isolating the power.
 Design a fail‐safe system for possible indicator and/or power failure.
