go-e Charger Gemini Flex (11 kW/22 kW) Installation and Operating Instructions

This quick guide refers to the original user manuals.
It serves as an installation aid for qualified electricians in the area of communication interfaces, but is not a substitute for studying the user manuals.

Install the go-e Charger Gemini flex charging station according to the installation instructions provided by go-e GmbH.

Please note that the site conditions of go-e GmbH apply.

Follow the instructions for the power supply for the go-e Charger Gemini flex charging station.

2.1. Ethernet connection

The go-e Charger Gemini flex has a Wi-Fi network interface and is connected to the FENECON Energy Management System. Please follow the steps below.

Please note that go-e Charger Gemini flex has a Wi-Fi communication interface (802.11b/g/n, 2.4 GHz). Set your Wi-Fi to a frequency of 2.4 GHz (channels 1–13 with the 2412–2472 MHz frequency band).

In a network, IP addresses are typically assigned automatically via DHCP. In many cases, this is handled by the internet router, e. g. a router such as a FRITZ!Box. This can then cause communication between the FEMS and the charging station to fail. To prevent this, IP addresses can be manually assigned.

2.2. Assigning an IP address via DHCP

Once connected to the customer’s network, the go-e Charger Gemini flex is assigned an IP address via DHCP.
This IP address can be found on the DHCP server, e. g. the router.

Please make a note of the assigned IP address. The IP address is required below to set up the FEMS App go-e lesend.

You can find the IP address of your go-e Charger Gemini flex in the go-e Charger app or in the device overview of your router (e. g., Fritz!Box).
