If that inverter is this one, it says:

"Back-up Capability with exceptionally fast transfer time just like the UPS - If incoming shore power is interrupted by external events like brownouts, the Freedom X automatically becomes an independent power source that supplies utility grade AC power to your loads when installed with
DC battery"

IMO you don't want it to automatically come on whenever you disconnect shore power. That means with this model, you do need to be able to disconnect the DC input.

ALL RV Inverter/Charger's IF TURNED ON, will automatically transfer to Inv connected loads if there is a Shore/Genset loss of power. If you do NOT want this to happen just turn the Inverter switch OFF. Doug

Yes, this is an inverter, not an inverter/charger. I am not clear on what they mean by "off" and "on" since it seems to have a small draw 4ma when in "off mode", but they also mention a draw 0.6a when "on" with no load. It says it can be turned "on" by the ignition switch method or by a manual remote.

Anyway, the owner's manual requires a disconnect on the DC input so that solves that I suppose.

"The DC circuit from the battery to the Freedom X must be equipped
with a disconnect and over-current device. This usually consists of a
circuit breaker, a “fused-disconnect”, or a separate fuse and DC
disconnect. Do not confuse AC circuit breakers with DC circuit
breakers. They are not interchangeable. The rating of the fuse or
breaker must be matched to the size of cables used in accordance
with the applicable installation codes. The breaker or disconnect
and fuse should be located as close as possible to the battery, in the
positive cable. Applicable codes may limit how far the protection
can be from the battery."

The OP should make sure it is not set to power the converter by inverter, only when there is "shore power" passing through.
