Wiring Ac Output; Wiring Dc Input - Growatt 10000TL3-S Installation & Operation Manual

5.4 Electrical Connections
5.4.1 Safety
Danger to life due to lethal voltages!
High voltages which may cause electric shocks are present in
the conductive parts of the inverter. Prior to performing any
work on the inverter, disconnect the inverter on the AC and
DANGER
DC sides
Danger of damage to electronic components due to
electrostatic discharge.
Take appropriate ESD precautions when replacing and
WARNING
installing the inverter.

5.4.2 Wiring AC Output

Conditions for the AC Connection
You must comply with the connection requirements of your utility operator.
All usages must comply with the regulations.
Residual-current protective device
The inverter is equipped with an integrated universal residual-current monitoring unit.
If the network operator stipulates a residual-current protective device, you must use a
residual-current protective device that triggers in the event of a residual-current of
300 mA or more.
Load disconnection unit
You must install a separate three-phase miniature circuit-breaker or other load
disconnection unit for each inverter in order to ensure that the inverter can be safely
disconnected under load.
Measure the public grid voltage and frequency (Voltage: 400Vac; Frequency:
50Hz/60Hz; 3-Phase);
Open the breaker between the PV inverter and utility;

Connection to the AC side terminal
1. The AC side terminals of the inverter are like the following figure,Fig. 6a, it is clear to
confirm that 'L1, L2, L3' represents three live line output, "N" represents neutral line
and
2. The five cables should be put through the protection shell, as Fig. 6 b, crimp five
standard cables with Cord End Terminal. Tighten all screws.Refer to Fig. 6c.
3. Fasten the protection shell onto the bottom of the inverter, make sure the four screws
are tightened, the completed appearance is like the below figure Fig. 6d.
