Figure 4.1: Submeter Connections
4.3: Ground Connections
The meter's Ground Terminal (PE) should be connected directly to the installation's protective
earth ground.
4.4: Voltage Fuses
Eaton recommends the use of fuses on each of the sense voltages and on the control power, even
though the wiring diagrams in this chapter do not show them.
• Use a 0.1 Amp fuse on each Voltage input.
• Use a 3 Amp fuse on the power supply.
