How to install the solar panels to a RENOGY ROVER 40A MPPT CHARGE CONTROLLER

[Lotus18]

I was wondering, if someone could help with wiring a camping solar panel to a Charge Controller? That solar panel works on a different Charge Controller (Eco-Worthy) but not this one, which I have just received 2 days ago... It is a RENOGY ROVER 40A MPPT CHARGE CONTROLLER. I attach all the cable correctly (battery in first and last out), but the Renogy screen stays blank.
