Wiring the Inverter
6.2.4 AC Wiring Considerations
The connection to the Amphenol AC connector for all models can be made with a exible or
rigid cable with a copper conductor that has the appropriate cross section according to table 6.1
and which has an installation condition that gives a correction factor equal to one. The AC cable
should be protected by a minimum type B 40 Amp breaker for 10 TL / 15 TL / 20 TL and minimum
type B 60 Amp breaker for 30 TL.
This connector is developed for connection to copper wires (for other applications please contact
Amphenol). The cross section of the cable should be calculated by considering the material used,
thermal conditions, length of the cable, the type of installation, and AC voltage drop.
Please note the cable length and the cable cross-section, due to the risk of undesirable tempera-
ture rise and power losses. In some countries, (e.g. France, Germany, Australia) system installa-
tion requirements have to be followed (UTE 15712-1, VDE 0100 712, AS/NZS 5033:2005). This
recommendation will dene minimum cable sections and protections against overheating due to
high currents. Please make sure that you follow specic requirements in your country.
For the security of your installation and for the safety of the user, please install required safety and
protection devices that are applicable for your installation environment (example: automatic circuit
breaker and/or overcurrent protection equipment).
WARNING
Death and serious injury may occur
In the case of damage or bodily harm resulting from the use of this device
in a way contrary to it’s intended purpose or as a result of unauthorized
modications made to the parameters of the inverter, Delta will not be held
liable in these situations..
The solar inverter must be grounded via the AC connector’s PE conductor. To do this, connect the
PE conductor to the designated terminal.
The AC connector is protected from unintentional disconnection by a clip mechanism which can
be released with a screwdriver.
The AC voltage should be as follows:
● L1-N: 230 V
AC
● L2-N: 230 V
AC
● L3-N: 230 V
AC
6.3 DC Connection (from PV array)
WARNING
Death and serious injury may occur
► When doing DC wiring, please ensure the wiring is connected with the
correct polarity.
► When doing DC wiring, please conrm that PV array’s power switch is
off.
