Three orions 30A dc-dc chargers - leave input cables and disconnect output

Hello,

I have to give my RV to mechanic and I would like to know how should I prepare the orions connections.

I’m pretty sure that this mechanic will disconnect the starter battery (it is standard procedure when working on a car) and I would like to know if it is safe to leave the input cables connected.

For output (auxiliary batteries) i have a fuse which have a button to connect/disconnect power and I can disconnect this auxiliary batteries easly, but for input next to the car starter battery - i have different fuses.

I would like to know if it is safe to leave the input cables connected and disconnect only the output cables?

In documentation I see that orions should be connected in this order:

1.Disconnect remote

2.Connect input starter battery

3.Connect output battery

4.Connect remote

in this order. So I believe that disconnecting should be in reverse order so I should disconnect output batteries (auxiliary batteries) first, and then input.

The question is - is it safe to leave the input cables connected? Im sure that mechanic will start the engine one or two times before he disconnect the starter battery (input) - will it burn the orions or not? later then he will disconnect the starter battery and then all orions will have no power from input and output - and it will be great, but there is a chance thet mechanic will start the engine with input connected.

Thanks in advance for help.

Regards,

Matt

With the remote out the orions wont power on. So it should remain Safe.

But don’t leave cables flapping in the wind so to speak. Make sure they are well taped or something when disconnected.

Great information - thanks.

I actually have fuses near auxiliary batteries - so I can easly switch them off without unplugging cables.

On starter battery side - it is all connected to the clamps, so mechanic will unplug the main clamp (positive and negative) without disconnecting actual cables.

But information that this little remote when is unplugged - will make my orions safe - is really useful.

Thanks again, and have a great day!
