III. Installation and Usage Guide

1. Méthode d'installation

Dimensions

– The meter counter display model has dimensions of 150mm×118mm×59mm, and the LCD display model is 160mm×112mm×58mm, both compatible with standard meter boxes.

Câblage

– Adopts 4 terminal blocks (1 for live wire input, 2 for live wire output, 3 for neutral wire input, 4 for neutral wire output). Installation must be performed by a professional electrician to ensure secure wiring and no short circuits.

2. Précautions d'utilisation

– Éviter l'installation dans un endroit humide, haute température, or strong magnetic field environments; it is recommended to install the meter in a well-ventilated location.

– Clean the meter body regularly to prevent dust accumulation from affecting heat dissipation and display performance.

– If verification is required, contact a professional metering institution; do not disassemble the meter by yourself.

3. Remote Meter Reading Configuration

– Connect to a concentrator or intelligent meter management system via the RS485 interface, supporting batch data collection and analysis.

– Can be used with the Chint Cloud Platform to realize functions such as real-time electricity consumption monitoring and electricity fee statistics (additional communication module is required).

IV. Common Issues and Maintenance

1. Troubleshooting

No Display

– Check if the power supply is normal, if the fuse is blown, or try restarting the meter.

Communication Failure

– Confirm whether the RS485 wiring is correct and whether the baud rate setting matches the system.

Abnormal Metering

– If inaccurate metering is suspected, use verification equipment to test the pulse output or contact the power supply department for verification.

2. Recommandations d'entretien

– It is recommended to conduct a comprehensive inspection every 5 years to ensure metering accuracy and equipment stability.

– Disconnect the power supply when the meter is not in use for a long time to extend its service life.

V. Modèles alternatifs recommandés
