The ATC should be independent of the caravan electrics so this should not be able to happen. Seems you have a wiring issue to get sorted.

I have the same mover. And either at the original fitting, or when it was returned to Truma for a new control box and activation motors. Someone managed to cause a short between the two systems. As a result. Using the mover activates the ATC . This has to be when taking the rollers off the wheels as the next time I come to use it the brakes are on. It took a long time to sus this out. I could not find the fault within the mess of wiring. So I fixed the problem by wiring the ATC to the van battery through a switch. Now, using that switch I can get the ATC to go through itโ€™s initialisation sequence and clear the problem. The switch is then turned off for normal use.
