Split PLC Power Rail Prepaid Electric Electricity Meters
The DDS5558is a Din Rail mounting split type single-phase prepayment meter operating with STS standard encryption algorithm. It is available with option for SMPS sustaining power supply, enabling the meter to work with stable performance even in brownouts, making it a sound revenue controller suitable for constantly unstable grid.
The meter operates in two parts: MCU, Metering Control Unit, and CIU, Customer Interface Unit. The CIU is a tactile and audible keypad with LCD display, normally installed under consumer's roof. The MCU, or the main meter is usually installed in a secure, locked enclosure-typically a pavement kiosk or pole-mounted equivalent. It is outside the consumer's premises to faciliate easy inspection by the utility at any time, thus reducing the possibility of tampering.
Thanks to the slim-line size and DIN rail housing, mutiple Power-Rail meters can be mounted in a small enclosure thereby making installation cost effective. It is ideal for installation in Granny Flats, Individual Rented Unit, Shops, Stores and sporting Facilities.
Connection between the meter and CIU is via a pair of communications wires. The MCU contains all critical metering, encryption, decryption and load control functionality. It operates independently of the customer interface unit and is immune to any form of tampering on the customer interface.

Cautions on Installation
1) Before wiring, please carefully check the connection diagram on meter case and confirm the phase line, and neutral line (ground wire) consistent with connection diagram. It is better to use copper wire and copper contact to connect to meter.
1) If the cable is old, operator shall cut the end of cable to ensure the new exposed wire end is about 15mm long to be used to connect; if cable diameter is between 3mm and 6.5mm, directly connect to inside of terminal and make sure it secured; if cable diameter is less than 3mm, then it is necessary to use a suitable size copper or aluminum bushing to clamp cable end so as to avoid loose contact of connection resulting in terminal burnout.
2) During PLC-connection, firstly loosen each screw on each terminal, then insert In-phase line into end of connection aperture and the in-neutral line into end of connection aperture, fully tighten screws of terminals. Similarly insert Out-phase line into end of connection aperture. Tighten screws of terminals fully and make them secured.
3) Power on energy meter to test the working condition, if energy meter works normally, record readings of meter. Otherwise, please carefully test condition of installation and connection and working voltage.
4) Be gentle with the energy meter so as to avoid dropping and collision during whole installation processes.
5) When installing energy meter, please be careful with operation and power usage safety so as to avoid accident.
