Key Specifications
1.3
•Input voltage: When the line voltage is less than or equal to 500 V, connect the meter
directly. When the line voltage is greater than 500 V, connect the meter through potential
transformers.
•Input current: When the input current is 0 A to 80 A, connect the meter directly (channel 1).
When the input current is greater than or equal to 80 A, connect the meter through current
transformers (channel 2).

3.1 Preparing Cables
The maximum torque of Ua, Ub, Uc and Un terminal screws is 1.7 N·m, and the
recommended torque is 0.9–1.1 N·m. The maximum torque of Ia*, Ia, Ib*, Ib, Ic*, Ic, RS485A
and RS485B terminal screws is 0.4 N·m, and the recommended torque is 0.15 – 0.25 N·m.

3.2 Wiring Scenarios
•You need to set parameters after cable connections are complete. For details, see section 4
"Display and Parameter Settings".
•This meter is generally used in commercial and industrial high-current scenarios. In external
CT scenarios, the precision of the secondary-side current is ±5 mA. For example, if a CT with
a transformer ratio of 400/1 is selected, the error is ±2 A. This meter is not recommended
in scenarios where the plant power is low or the control precision of the grid-connection
point is high. Instead, use a meter with higher precision.
