An interlocking device for monitoring and enforcing shipping and acclimation conditions includes a servo motor, at least one locking pin, a battery, and a printed circuit board disposed within an enclosure, where the battery is electrically coupled to the servo motor and the printed circuit board. The interlocking device further includes a housing of an input power connector insertable into a first end of the enclosure to prevent the housing of the input power connector from electrically coupling to a power source, where the servo motor is configurable to engage the at least one locking pin to prevent a removal of the housing of the input power connector while inserted in the first end of the enclosure. The interlocking device further includes the printed circuit board configured to control the servo motor based on readings from one or more sensors electrically coupled to the printed circuit board.
