The table below describes the routing path and connection methodology for the optional
neutral conductors that may be connected to the inverter’s transformer to satisfy effective
grounding requirements. The inverter enclosure is designed with a routing path to allow for
proper bending space of these conductors, and therefore the path shown below should be
followed. The transformer’s neutral bar has also been designed with a set of holes to allow for
various field connections such as a box lug or a crimped lug.
