Abstract
An HVAC actuator may include a rotatable output shaft, a drive mechanism configured to selectively drive the output shaft, two or more wiring terminals, and a removable blocking tab configured to block wire attachment to at least one of the two or more wiring terminals. When the removable tab is removed, wire attachment to the previously blocked at least one wire terminals may no longer blocked. The removable block tab may be a break-away tab. The HVAC actuator may include a housing enclosing the drive mechanism, and the break-away tab may be integral to the housing. In some instances, the removable tab, once removed, is not configured to be reattached, but this is not required.
