# 120V North America Home-Style PRO300 / Universal Harness Installation

| The Airwallet Pro is designed for machines with coin acceptance terminals. Home-style machines do not have that. However, the Airwallet Pro is capable of controlling a relay that can control the power to the machine. This relay can be provided by Airwallet and installed together with the Airwallet Pro as illustrated (below).
