* 1：110 V, 220 V direct connection is possible. For the circuit over this voltage, transformer (VT) is
necessary (Primary voltage of VT can be set up to 6600 V, and secondary voltage of VT can be set up
to 220V as optional setting). Star – delta connection and delta – star connection transformer instead of
VT cannot measure definitely to be out of phase. Please use a transformer of the same connection.
* 2：5 A primary current can be set when using the current sensor is as follows.
5A, 6A, 7.5A, 8A, 10A, 12A, 15A, 20A, 25A, 30A, 40A, 50A, 60A, 75A, 80A, 100A, 120A, 150A, 200A,

4000A, 5000A, 6000A (Primary current of CT can be set up to 6000A in any . However, secondary
current of CT can not be set to other than 5A).
* 3：Please refer to 2 (1) as for the ratio error of the current sensor.
* 4：Demand shows the moving average of a set period.
* 5：Always accumulating the integrated values of Wh and varh. It can capture short-cycled load fluctuation.
