Wiring
If the sensor is installed in a high-voltage environment and a fault condition or installation error
occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme
caution when making contact with the leads and terminals.
Note
Do not apply high voltage (e.g. AC line voltage) to the transmitter terminals. Abnormally high
voltage can damage the unit (bus terminals are rated to 42.4 VDC).
