• Pass the AC cable
through the AC
cable gland
(23).
• Strip the AC cable
and wires
• Install ferrule with plastic collar on the wires.
• Install the wires (based on the AC connection type) respecting the
connections as indicated on the screw terminal block (L1=R ; L2=S ;
L3=T):
A.Five-cores cable (L1, L2, L3, N and PE).
B.Four-cores cable (L1, L2, L3 and N).
C.Four-cores cable (L1, L2, L3 and PE).
D.Three-cores cable (L1, L2, L3).

In case of a wrong phase sequence the inverter will
not connect to the grid and it will provide an error state.
• Re-install the screw terminal block inside the AC quick fit connector.
ATTENTION –
A
Push the screw terminal block till a double “click”
will be heared.
• Tighten the cable gland ring (7.5Nm).
ATTENTION –
A
Make sure the cable glands are properly sealed to
ensure to keep IP65 protection degree.
7.5.1 Connection of AC quick fit connector to the inverter
• Pull out the protective cap from the AC output connector
(17)
.
• Connect the AC quick fit connector
(09)
to the AC output connector
(17)
.

A
Push the connector till a double “click” will be heared.
• Secure the AC quick fit connector. Install and screw the holding clip.
ATTENTION –
A
The AC quick fit connector must not be subject to
tensile forces (examples: do not connect weights to the AC cable, do
not leave excess cable windings hanging, etc).
8. Input connection (DC)
For the strings connections it is necessary to use the DC input quick fit
connectors
(13)
, located on the bottom side of the inverter.
13
The input connectors are divided into 2 groups (one group for each input
MPPT). For each MPPT 2 pairs of quick fit connectors are available.
Respect the Maximum DC input power for each MPPT as follow:
MPPT
PVS-10-TL
PVS-12.5-TL
PVS-15-TL
IN1
17A / 7.8kW
18A / 8.3kW
22A / 10kW
IN2
17A / 7.8kW
18A / 8.3kW
22A / 10kW
8.1 Preliminary operations to the connection of
the PV generator
• Checking the correct polarity of the strings
• Checking of leakage to ground of the photovoltaic generator
• Checking of strings voltage
• Installation of quick-fit connectors
8.2 Connection of the input strings
WARNING –
B
When the photovoltaic panels are exposed to sunlight
they provide continuous DC voltage to the inverter. To avoid risks of
electrical shock, all wiring operations must be carried out with the DC
disconnect switches (internal
(07)
and external to the inverter) and
external AC disconnect switches OFF.
• Connect all the strings required by the system by pushing the quick fit
connectors in the right position.
ATTENTION –
A
Using coupling parts that are not compliant with
the quick fit connector models on the inverter could cause serious
damage to the unit and lead to invalidation of the warranty.
