How to reset an Elfin EE11A modbus-to-ethernet adapter

Hardware

Hi,

I need to factory reset an Elfin EE11A RS485 to Ethernet converter (which is used to read Modbus data from a SUN2000-12KTLM2 solar power inverter and send it to Home Assistant on a Raspi via the Huawei Solar integration.

Problem: How can the Elfin be resetted?

Information from the manufacturer is scarce.
For the EW11A, the manual says to “connect reload pin to GND” for reload (<1.4s) and factory reset (>4s). But the EE11A, doesn’t seem to have a reload PIN:

Has someone managed to reset/reload a EE11? Is there another way to re-configure the converter?

Help is highly appreciated!

There’s a flying l lead on an elfin ew11a, which makes the required short for you when you press the button.
