You can use that exact diagram. But you can't run both elements at once - That would be 7500 watts and pull 32 amps. You only have 30 available.
Volts * Amps = Watts,
So Watts / Volts = Amps
So 1500 / 240 = 6.25 Amps
And 2000 / 240 = 8.4 Amps
You could run a 4500 ish watt element and a 2000 watt element together: 6500 / 240 = 27 Amps
But you'll be running awefully close to the rated limit of your system, and risk popping the breaker.
