b) Time of Use (TOU) , multi-tariff, holiday setting

c) Easy connection to User Interface Unit (UIU) for split type applications

d) 15 year designed life

e) Balance alarm can be set by user according to his own need

Safety precautions:
- Use only isolated tools.
- Do not connect the meter to a 3 phase - 415V AC - network.
- Place the meter only in dry surroundings.
- Make sure the used wires are suitable for the max current the meter can measure.
- 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.
