Wire Connection
Note: 1. For voltage input connection terminal,bracket terminals (Ua) (Uc) (Ub) shows 3 phase 3 wire connection method,
2. Current input is current input terminal , all the inputs and outputs must be coherent
Model 1: (3pcs CT) 3 phase 4 wire working mode
Model 2: (2pcs CT): 3 phase 3 wire working mode

Voltage input via PT
Explanation :
A. Voltage input: Input voltage should not be higher than the rated input voltage of meter, otherwise a PT should be used.
B. Current input: Standard rated input current is 5A. A CT should be used when the input current is bigger than 5A. If some other meters are
connected with the same CT , the connection should be serial for all meters.
C. Please make sure that the input voltage is corresponding to the input current, they should have the same phase sequence and direction,
otherwise data and sign error may occur (power and energy).
D. The connection mode of meter which is connected to power network should depend on the CT quantity. For 2pcs of CT, it should be 3 phase
3 wire connection. For 3pcs of CT, it shoud be 3 phase 4 wire connection.
E. Please pay high attention on the difference between 3 phase 3 wire and 3 phase 4 wire connection , becasue wrong connection may lead to
incorrect calculation of power factor, power and energy .
