4.3.2 AC Circuit Breaker And Residual Current Device
An independent three or four pole circuit breaker for each inverter must be installed at the output
side to ensure that the inverter can be securely disconnected from the grid.
The internal integrated residual current detection device (RCD) of inverter can detect external
leakage current in real time, when detecting the leakage current value exceeds the limit value, the
inverter will be disconnected from the grid as soon as possible. If an external RCD is installed , the
action current should be 500mA or higher.
4.3.3 Earth Terminal Connection
The inverter is equipped with earth terminal according to the requirement of EN 50178.
All non-current carrying exposed metal parts of the equipment and other enclosures in the PV
power system should be grounded.
Please connect 'PE' cable to ground.
1. Strip the wire insulation sheet of a suitable length with a wire stripper.

2. Insert the stripped wire into the terminal and compress it tightly by crimping pliers.
Step 3:
From the accessory bag terminal, set on the wire and tool clamping.
Use tool clamp terminals
If use line pressing pliers, wire diameter
smaller two separating, crimping terminal
shape rules after no prominent spikes.
Insulation casing spin out completely
covered terminal wire tube.
Insulation casing set to the
cable.
Put the cold-press terminal
received cables.

GEP30~35-L-10/GEP50~60-10 models using cold pressed terminals
GEP12~20-L-10/GEP25~36-10 models use terminals
Step 4:
Use flat head screw driver side screw counterclockwise communication terminals,
make five interface is open.
Step 6:
The communication terminal cover closed, using communication connection cap
screw clockwise twist will exchange cover tighten.(2.3 N.m fastening torque).
Step 5:
The communication cable line according to the sequence access communication
terminal station, then twisting the screw clockwise (2.3 N.m fastening torque).
