The cover of the EV-300 control unit states mounting arrows up to indicate the unit should be mounted to a vertical surface.
What would happen if the control unit was mounted horizontally, would this affect performance etc?

Hi Offshore Dave

Thank you for your enquiry

The EV sensor (the black disc part with the green LED) needs to be mounted in a horizontal plane for the internal sensors to operate correctly, see below

The sensor itself can be mounted flat onto a horizontal surface without using the white bracket, or the sensor can be mounted onto a vertical surface using the bracket to ensure the sensor remains horizontal.

Regards
