CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input
common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not,
hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential
of the user input common with respect to earth ground; and the common of the isolated plug-in cards with respect to input common.

The power supplied to the meter shall employ a 15 Amp UL approved circuit breaker for AC input and a 1 Amp, 250 V UL approved fuse for DC input. It shall be
easily accessible and marked as a disconnecting device to the installed unit. This device is not directly intended for connection to the mains without a reliable means
to reduce transient over-voltages to 1500 V.
