Install three-phase energy meter D103

The D101 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.

Depending on the configuration, the device can be supplied with transformers of different types:

• Type 1 - transformer ring, connects to pins 3-4 of the deviceа
• Type 2 - plug-in transformer, is connected to the socket 5 of the device.

To connect the device, follow these steps:

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