Ac On-Grid And Ac Back-Up Output Connection - Salicru EQUINOX EQX2 3001-HSX User Manual

5.3.5. AC ON-GRID and AC BACK-UP
output connection.
Before connecting to the grid, make sure that the voltage and
frequency of the grid meet the inverter's requirements. Please refer
to the technical parameters for more details.
This inverter includes a built-in residual current device (RCD).
If an external residual current device (RCD) is used, a type B device
must be used, with a trip current of 30 mA or more.
5.3.5.1. Warnings to consider during
the connection.
A separate AC circuit breaker is required on the grid side and
1.
on the battery side. No load should be connected directly to
the inverter.
Before connecting the AC cable, make sure that both the AC
2.
and DC sources are disconnected from the inverter.
The EQX2-HSX series single-phase hybrid inverter connects to
3.
a 230 V, 50/60 Hz grid.
The AC cable and AC circuit breaker recommended for the
4.
EQX2 HSX series 3~8 kW single-phase hybrid inverter are
shown in the table below:

Fig. 54. Stripping the AC cable.
Remove the ferrules included in the accessory bag from the
4.
AC ON-GRID connector and crimp them to the stripped ends of
the L/PE/N cables with an approved tool to ensure an optimal
connection.
Remove the AC ON-GRID connector from the accessory bag.
5.
Insert the ends of the three cables into the corresponding
6.
holes on the connector: yellow-green cable into the PE port,
phase into the L port and neutral into the N port. Make sure
the cables reach the back of the connector and screw them
in tightly. Pull slightly on the cable to check that it is properly
connected.
Connect the AC ON-GRID connector to the AC ON-GRID
7.
terminal on the inverter, as shown in Fig. 55 below.
