Connecting the AC Input Power Cable
3.7.2
Connect AC input power cables of the SmartACBox to input circuit breakers QF01 to QF05 and
QF07 to QF11. It is recommended that AC input power cables be routed to input circuit breakers
QF01 to QF05 through AC input cable hole 1 and be routed to QF07 to QF11 through AC input
cable hole 2.
1. Remove an appropriate length of the jacket and insulation layer from each AC input power
cable using a wire stripper.
•
The lengths of the jackets and insulation layers
that need to be removed from the AC input
power cables to input circuit breakers QF01 to
QF05 are different. When connecting a stripped
cable, ensure that the exposed insulation layer is
in the enclosure, and the jacket is outside the
enclosure.
•
For the lengths of the jackets and insulation
layers that need to be removed from the AC input
power cables to input circuit breakers QF07 to
QF11, refer to the AC input power cables to input
circuit breakers QF01 to QF05.

2. Crimp OT terminals.
3. Route the cables through AC input cable holes 1 and 2.
4. Connect each AC input power cable to the U, O, and W terminals of the circuit
breaker, and use a torque screwdriver to tighten the bolts.
To avoid device damage, do not mix up the U, O, and W terminals when connecting cables.
