and may adversely affect the Sensor.
heat radiation from the body of the S3D2 may cause the insides of
protective casing to heat up.
power supply inputs are to be used as is for the Sensor power
supply outputs. Connecting a load of 1 A min. to the Sensor’s power
supply outputs will cause the fuse in the case to break.
