Standard configuration 5and1 (99999.1KWh) LCD screen. Passive standard configuration pulse output (polarity), optional remote pulse output passive (polarity). Easy access to different AMR systems, in accordance with IEC 6205331 and DIN43864 standards. Two LEDs indicate power status (green) and power pulse (red). Unidirectional measurement of single-phase, two-wire active power consumption. This is independent of the direction of the charging current. Complies with IEC 62053-21. Direct connection operation, two connection modes can be selected. S type connection is standard configuration, U type connection is optional. Extend the terminal cover for safe use. Package list: 1 energy meter 1 user manual Note: 1. When installing the instrument, connect the cables according to the wiring diagram in the user manual 2. The instrument should be installed in a dry and stable place, can be installed indoors, avoid direct light, humidity, heat, mildew, smoke, dust, sand and gas corrosive 3. After the test seal can be installed and used, unsealed or the storage time is too long, the instrument can be retested 4. Only an experienced electrician or professional technical personnel can install the meter, please read the manual 5. Should be installed on the refractory wall, not easy to shake 6. It is recommended to use copper wire entry when wiring, to avoid poor contact caused by burning the table 7. When the meter is correct, the indicator light will turn on. The meter's load capacity is between 0.05lbs and lmax, excessive capacity will result in burnout.
