The ELS input needs LAN/inc in the ecliptic coordinate system. For an Earth equatorial orbit, you need an ecliptic LAN of 180° and an ecliptic inclination of 23.45°. This corresponds to the ascending node of earth's equatorial plane through the ecliptic plane. This might be the opposite LAN of what you might expect since the origin of the ecliptic coordinate system is the vernal point which is actually defined as the ascending node of the ecliptic plane though the equatorial plane.
