* Neutral wire is blue, live wire is brown (preferred) or black and protective earth wire is yellow-green.
* Rotate (tightening torque: 0.6N.m) the connector of AC cable into the corresponding terminal.
4.3.2 AC circuit breaker and leakage current protection device
Please install an independent two pole circuit breaker to protect the inverter and make sure it is
safe to disconnect it from the grid.
In addition to the built-in RCMU, an external RCD is required to ensure that the inverter system
does not carry DC residual currents. To avoid tripping, the types A can be used.
Inverter Model
GEP3.6-1-10
GEP4.2-1-10/GEP5.0-1-10
Note: it is not recommended that multiple inverters share a single circuit breaker.
The integrated leakage current detection device of the inverter can detect external leakage current
in real time. When the detected leakage current exceeds the limit value, the inverter will quickly
disconnect from the grid. If the leakage current protection device is installed externally, the action
current should be 300mA or higher.
4.3.3 DC Side Connection
1. Before connecting the PV strings, please ensure the plug connectors have the correct polarity.
Incorrect polarity has the potential risk to cause permanent damage to the inverter.
2. The open circuit voltage of the PV strings cannot exceed the maximum input voltage of the
inverter.
3. Only the DC connectors supplied by the manufacturer are suitable for use.
4. The positive and negative pole should not be connected to the PE wire (ground wire). Not follow-
ing this instruction may cause damage to the inverter.
5. Red wire represents positive, black wire represents negative.
6. For the GE series the minimum insulation resistance to the ground of the PV panels must exceed
20kΩ(R=600/30mA). There is risk of electric shock if this minimum resistance requirement is not
met.
Note:There is risk of burning if the DC connector is not connect tightly,you can hear the
"Click" sound to confirm the connectivity.
