Orion TR Dual Ignition Input

I have an Orion TR Non-Isolated DC-DC 30 amp charger installed in my twin engine boat. I'd like to connect both 12v ignition lines to the H pin so that the charger operates when either engine is running. Does anyone know if this would cause any issues when both engines are running and providing 12v to the H pin at the same time? Thank you.

You can use two diodes to combine the inputs, while preventing backfeed.
