Use a Type SO power cable to connect the primary power to the SR-45i power
supply. The power cable should have a 600 volt minimum rating and should be
sized according to local and national codes. Route the power cable through the
strain relief on the rear of the power supply and connect the hot lines to the input
terminals on the safety contactor CON1 as shown in Figure 3-1. Note that the
center terminal of CON1 is not used in single phase systems.
Be sure to connect
the primary ground cable to the ground stud on the sub-panel
.
