2. Secure the device by sliding the latch up.
The connection of the device to the mains must be carried out by
trained personnel with a permit of at least group III for electrical
safety when working on installations up to 1000 V
To connect the device, run next steps:
1. Connect the leads of the current transformers to the device
according to the wiring diagram. If your transformers are
equipped with a quick plug, do not connect them to a running
device.
Connecting a transformer plug to an operating device
may damage the device.
2. Slide the current transformers over the wires of the 1st, 2nd and
3rd phase. Current transformers are numbered (1-2-3) and have a
power direction indicator. It is accepted that the energy moves in
the direction from the electricity meter towards the consumers.
Installing the current transformers in accordance with the energy
direction indicators will give the best measurement accuracy.
3. Connect three phases and a neutral wire to the device in
accordance with the connection diagram.
