The Positive connection (load return bus) for the power plant must be connected to the principal ground point of the building where installed. Do not connect the Battery Return Bus to the principal ground point of the building. One set of M8 threaded holes on 25.4 mm (1 in.) and 4.45 mm (1-3/4 in.) centers for connection of a two-hole lugged cable are provided on both the small and large load return modules for the connection to the building principal ground point. Any connection to the principal building ground point should be done with due consideration to all applicable local codes.
