2. General Introduction The CL730D22L three-phase CT operated smart energy meter is the latest developed products in CLOU's meter series. It is certificated with MID and DLMS/COSEM, it provides an excellent and stable accuracy and performance. The meter is equipped with a plug-and-play communication module such as PLC/RF/Cellular for AMI integration, so all the operations can be done remotely from the central server, including meter billing/configuration/alarm events upload etc. It keeps records of different tampers which can be configured to switch off the load supply when the tamper occurs. The CL730D22L meter provides TOU multi-tariffs, neutral current and maximum demand measurement. The meter is equipped with communications ports to support AMI applications, in accordance with the DLMS/COSEM standard. It is able to equip with an integrated relay enables the remote connection and disconnection of the external relay. The meter’s application software can be upgraded via local or remote communications. The meters are designed to conform to the latest standards and requirements of electricity utilities, providing a strong foundation for Smart Grid initiatives.

4. Safety Information Meters shall be installed and maintained only by suitably-qualified personnel. The operator must read the following safety advice when performing installation or service work on meters. This technical manual is written for meter installers and for service departments of utilities. The End-user gets a quick reference guide, packed with each meter. In each chapter of this manual, various letter symbols and graphic symbols which are adopted to express danger according to different levels of danger will be explained. Please pay attention!

Warning!

Attention!

              

This sign is to remind of possible danger, which will possibly cause some sever hurt and damage to people and the equipment. This sign is to remind of possible unexpected situation, which might result in personal injury, equipment damage and data error.

Pay attention to product measured load capacity. Correct and reliable installation and connection. Pay attention to effective cross-sectional area of wire connection. Don’t touch bare wire or use bare wire to connect. Don’t use product in an explosive environment. Keep product surface clean. Don’t immerse meter with water and any chemical substance or use chemical substance to clean meter. Displays in the manual are all examples, which may have some difference from the real data in meters. Since it’s life-threatening to touch live components, power must be cut off before installation and replacement. Please obey local rules. Installation and replacing of meter only could be done by qualified person with specified technology. When installing meter, pay attention to meter’s safety. Meters that have appearance damaged or ever fallen down are not allowed to install. Washing meter with water are not allowed. The CLOU Standard applies to production and test in CLOU Electronics, not the standard for client test or acceptance. Only IEC standards apply to the client inspection and acceptance. Before installing or removing a meter, or removing the terminal cover for any reason, insulate the meter from the mains power supply. Always disconnect all measurement and auxiliary circuit connections from the meter before attempting to open the meter housing.
