6.2.2 Wiring Diagrams
・
Please connect a breaker to the voltage input part for safety reasons and to protect the device.
・
Grounding the secondary side of VT(Voltage transformer) and CT(Current transformer) is not
necessary with low-voltage circuit.
◆
When measuring a load with rated input voltage (100-200V system)
Single-phase two-wire system
＊
One current transformer (CT) is required.
