5.3.5.1. Warnings to consider during the
connection.
An AC circuit breaker must be inserted between the loads and
1.
the inverter, as none should be connected directly.
Before connecting the AC cable, make sure that both the AC
2.
and DC sources are disconnected from the inverter.
The EQX2-HT series of hybrid three-phase inverters connects
3.
to a 400 V AC, 50/60 Hz three-phase grid.
The AC cables and circuit breakers recommended for the
4.
three-phase hybrid inverter from the EQX2 HT 4÷12 kW
series are shown in the following table:

50 mm, and remove the insulation from the end of cables L1,
L2, L3/PE/N by about 8 mm, as shown in Fig. 52.
Cable diameter: 12÷18 mm.
Fig. 52. 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 L1, L2, L3/PE/N cables with an approved tool to ensure
optimal connection.
Remove the AC ON-GRID connector from the accessory bag.
5.
Insert the ends of the five cables into the corresponding
6.
holes on the connector: yellow-green cable into the PE port,
3 phases into the R, S, T ports 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. 53 below.
