The DDSK150 consists of two parts. A customer interface unit (CIU), and a metering and control unit (MCU). A CIU is a keypad based display, to be installed within consumers homes wherever there is a plug point. A MCU is the main meter, installed away from consumer's home in a kiosk, meter box or a pole-mounted enclosure .MCU communicates with CIU via wireless communication such as Power Line Carrier (PLC), Radio Frequency(RF), and LoRa. This non-wired setup allows for easy inspection by utility and service providers at any time without visiting consumers' houses and reduces the chance of fraud by tampering.
- Use only isolated tools.
- Place the meter only in dry surroundings.
- Make sure the AC wires are installed correctly before activating the current/voltage.
- Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
- Installation, maintenance and repair should only be done by a certified electrician.
- Never break the seals or open the front cover as this might influence the functionality of the meter.
- Do not through, drop, kick or other physical violence to the meter as there are high precision components inside that will break or make the meter measure inaccurate.
- Do not mount the meter in area's with harm gas, dust, mildew or insects or on unstable surfaces.
