Notes: All input AC circuit breakers are of the “high inrush” type to prevent nuisance tripping during power-up.
Wiring and connections must meet the requirements of the National Electric Code, state and local codes
and requirements, and the requirements in this manual.
To connect the input AC voltage, route the AC conduit through the appropriate knockout hole. See
SECTION 6.3. Route the AC wiring to terminal lugs AC1 and AC2 located above the AC breaker as
shown in FIGURE 6.1-2. For proper connection, torque the AC1 and AC2 terminal strip screws to
18 inch pounds (2Nm), and the ground lug screw to 35 inch pounds (4Nm), see FIGURES 6.1-2
and 6.1-3.
