2.13. Shunt trip installation (optional)
Verify if in your country this feature is mandatory before installing the equipment.
eProWallbox
is equipped with an AC normally open contact (CN3). To ensure correct selection
of the shunt trip device, it is necessary to bear in mind that the contact on the
eProWallbox
has
the following characteristics: rated 3A 250V, programmed to command a Shunt device in
accordance with IEC 61851-1 standard. If a fault occurs in the internal switching device, this
function is used to command the opening of the MCB (or similar safety device) placed upstream
of the
eProWallbox
.
External devices used for this purpose can include:
Motorized RCD
Auxiliary contact of MCB
Any other type of device compatible with this type of contact and with the above rating
chosen by the installer.
The shunt trip device must be selected by the installer compatibly with the MCB device
identified for correct installation.
Couple the shunt trip device to the compatible MCB, following the instructions on the
respective installation manuals
Connect the signal cables of the shunt trip device to the CN3 “push-in” terminal of the
electronic board.
2.14. Closing operations and power supply
1.
Check to ensure the power supply cables are connected properly, making sure that
the respective positions of the phases and neutral in the CN1 terminal block respect
the markings.
