Sense is connected to dangerous voltages. Improper use or installation can be dangerous or even fatal. Please make sure to follow these guidelines:

1.  The installation should be conducted by a qualified professional, according to local electrical codes.
2.  Personal protective equipment should be worn when installing a current sensor on a conductor exposing hazardous live voltages. If the current sensors are used in a manner other than specified, the safety protection provided may be impaired.
3.  Do not try to open the Sense monitor, touch any internal parts, or try to repair it.
4.  If you believe the monitor, sensors, or cables may have been damaged, do not try to use them.
5.  Use the Sense monitor only in the United States and Canada, and only with a 60Hz 120V/240V split phase system.
6.  Install the Sense monitor where it will not be exposed to direct sunlight or extremely low or high temperatures. No exposure to water. RH < 90%; Elevation < 2,000 meters; Temperature 0 – 68°C.
