Install three-phase energy meter D103

The D103 can be installed in an electrical panel on a DIN rail or on a wall using the DIN rail strip that is supplied in the kit.

The device should be connected to the power grid by trained personnel with a minimum of group III approval for electrical safety when working on installations up to 1000 V.

To connect the device, follow these steps:

1. Connect the current transformer wires to the device in accordance with the wiring diagram.
2. Slide the current transformer on the phase conductor.
   The transformer has an energy direction indicator, from the electricity meter towards the consumers.
3. Connect the phase and neutral wires to the device in accordance with the wiring diagram.
