In 4.4, the matters needing attention:
4.1.1. auxiliary power supply
Multifunction power meter auxiliary power switching power supply, if not for the special statement, with the AC/DC85~265V power supply interface, ensure that the power supply provides for the series of products, in order to prevent damage to the product. (DC power supply is "1", "2" is negative)
①, recommended to install the 1A fuse in power line.
Second, for the power quality is poor, recommended to install surge suppressor and fast pulse suppressing device in the power supply circuit.
4.4.2. signal input
Calculation by each measurement channel separate collection, ensure the use of the same, symmetry, which has various connection mode, suitable for different forms of load.
①, voltage input: input voltage should be less than the rated input voltage products 120%, otherwise it should consider using the PT; installation 1A fuse in the input voltage;
Second, the current input: input current should be less than the rated input current products (1A, 5A) 120%, you should use an external CT;
If the use of the CT is connected with other instruments, wiring should be used in tandem;
Recommend the use of wiring row, not directly connected with CT, in order to assemble; prior to the removal of the current input line of products, we must first disconnect the CT a circuit or short circuit two times.
Third, to ensure that the input voltage, current, phase sequence and wiring diagram consistency, direction should be consistent, otherwise it will numerical and symbolic power, electric energy error!
Connection mode, the instrument outside, to be consistent with the internal network settings, three line three line NET=N.3.3; three-phase four wire NET=N.3.4. Set the inconsistent cause a voltage or power is not correct.
The 4.4.3 notes:
①, communication connection is recommended to use three core shielding wire, each core cross section is not less than 0.5mm2, are respectively connected with the A, B, grounding, shielding layer of the ground, wiring should enable the communication line from the power cable or other strong electric field environment.
In the end, suggest that A, B and instrument matching resistance, resistance range is 120 ～ 10K Ω (according to the bus connection to the instrument number of different resistance range similarities and differences, the general 32 the following instruments incorporated with 120 Ω resistor is bette
