SELECTING THE VOLTAGE FUSES

CHAPTER 3: ELECTRICAL INSTALLATION

3.4Selecting the Voltage Fuses

We strongly recommend using fuses on each of the sense voltages and the control power, although connection diagrams do not show them. Use a 1 Amp fuse on each voltage input.

The meter can handle a maximum voltage of 150V phase to neutral. PTs are required for higher voltages. Suffix -G extends the maximum direct voltage to 300V phase to neutral, 600 volt phase to phase.
