Title
Connect the phase (L1, L2, L3), neutral (N) and earth (PE) wires of the AC grid input to the GRID terminal
block respecting the correct assignment:
•
Phase (L1)
→
L1 terminal
•
Phase (L2)
→
L2 terminal
•
Phase (L3)
→
L3 terminal
•
Neutral (N)
→
N terminal
•
Earth (PE)
→
PE terminal
Be careful not to reverse the phases with the neutral. If this happens, the system may present malfunctions.
In this case, the xStorage Home 3P detects the fault by disabling the operation and signaling the problem
with a specific alarm code.
In order to minimize electromagnetic disturbances, it is required to install the EMI suppression toroidal ferrite
cores supplied in the box on the cable connected to the AC GRID input.
6.3.1 Reduction of electromagnetic disturbances – EMI suppression ferrite cores installation
Refer to the installation instructions shown in
Figure 8
.
The xStorage Home 3P may be not compliant with the EMC standards requirements if the ferrite cores are
not installed according to the instructions provided.
Refer to the application wiring diagram shown in
Figure 9
.
WARNING:
Make sure to comply with the local regulations to set up an auxiliary off-grid power supply
system in case of a power outage.
WARNING:
The power supply system of the loads connected to the EPS port for
off-grid operation
relies on an external interlocking system that automatically disconnects the part of the system
composed by the xStorage Home 3P and the loads connected to it from the distribution network.
The interlock system must be provided in compliance with the safety requirements of the current standard.
WARNING:
The NEUTRAL conductor (N) of the EPS port is floating. If local regulations require that the
NEUTRAL conductor (N) must be connected to the earth potential,
it is necessary to provide an external
electrical connection between the PE protective conductor and the NEUTRAL conductor connected
to the EPS port.
Not providing the connection between NEUTRAL and PE can lead to the malfunction of
the RCD protection systems provided for the privileged line and placed downstream of the inverter and / or
to the malfunction of the connected loads.
