As long as the outside disconnect is lockable and the technician actually uses a lock, it should be code compliant. But testing of the inside unit may then require a lot of running back and forth between inside and outside.A technician working on the unit would know to turn off the disconnect. At least he/she should or they have no business working on them. I never saw in the instructions, on the ones that I have installed, where there was any mention of an inside disconnect.
Even if they do not specifically mention an inside disconnect, the instruction typically include the CYA requirement that the installation must be done in accordance with the applicable electrical codes.
