CHAPTER 3: ELECTRICAL INSTALLATION

CONNECTING THE VOLTAGE CIRCUIT

3.3Connecting the Voltage Circuit

For proper meter operation, the voltage connection must be maintained. The voltage must correspond to the correct terminal.

The cable required to terminate the voltage sense circuit should have an insulation rating greater than 600V AC and a current rating greater than 0.1 A.
