Figure 2-5. AC Input Connector and Safety-Ground Stud
A 1-Phase input is connected to terminals L1/L2 or L2/L3 (do not connect a 1-Phase
input between L1/L3), while a 3-Phase input is connected to L1/L2/L3 (a connection to
neutral is not utilized with 3-Phase input). The connector has compression terminals
with female contacts. A ground connection must always be made to the utility earth
protection ground using the AC Input connector pin or rear panel safety-ground stud.
