optocoupler output protection
The outputs from the opto device (C and E) are effectively a BJT collector and emitter. It will not produce any voltage to drive the LEDs therefore the LEDs will not activate. This means the TVS on each is pointless: -



Here's how you interface the output: -



You need a power supply on the transistor side and a resistor to current limit the transistor. An LED can be inserted in series with the resistor.
