4.4 Communication Connection
After the replacement of the Wi-Fi/LAN, the new module can work only after restarting PV array
connected to the inverter.
4.4.1 Wi-Fi Communication
Wi-Fi communication option is only applicable to Wi-Fi version inverter and Wi-Fi communication
module is required. Please refer to "WIFI/LAN Configuration Instruction" in the accessory box for
detailed instruction.
The Wi-Fi module installation of GEP inverter is shown below.
4.4.2 LAN Communication
LAN Communication is only applicable to LAN version inverter and LAN Communication module is
required.
4.3.4 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 must be grounded.
Please follow the steps below to connect "PE" cable to ground.

L2 = L1 + (1~2mm)
Step 1
Strip the wire insulation sheet of a suitable length with a wire stripper.
Step 2
Insert the stripped wire into the terminal and compress it tightly by crimping pliers.
Step 3
Fix the earth wire
In order to improve the corrosion resistance of the terminal, it is recommended to apply
silica gel on the earth terminal for corrosion protection after the grounding cable connec-
tion is completed.
This port is used for connection of Wi-Fi or LAN module only. No connection to USB is
allowed. Do not connect PC or other device to this port.
