3.5.2 In case of using main unit and connected expansion units

Please connect a breaker (3 to 15A) to the power supply (voltage input) part for safety reasons and to
protect the device.

Single-phase two-wire system

◆

When measuring a load with rated input voltage

Note)
(1) When wiring CT, wire correctly according to this, K for power supply side and L for load side.
(2) Using all CTs for one unit should be same.

◆

When measuring a load with exceed input voltage.

Voltage transformer (VT) is needed when you measure a load with over rated input voltage.
Use VT, its secondary side rating is 110V.
Even if the secondary side voltages of VT are same, when the power source system is different, one
main unit is necessary for each power source system.
(Refer to the previous 3.6.1 in detail.)
