5.8 Installing the AC Input Power Cable
Prerequisites
The AC input power cable and OT-M5 terminal are available.
Context
Connect the AC input power cable from the SmartACBox to input circuit breakers QF01 to
QF12. Recommended: Route the AC input power cables to input circuit breakers QF01 to
QF06 through cable hole 1; route the AC input power cables to input circuit breakers QF07 to
QF12 through cable hole 2.
Procedure
Step 1
Remove an appropriate length of the jacket and insulation layer from the 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 QF06 are different. When connecting a
stripped cable, ensure that the exposed insulation layer is all in the enclosure, and the
jacket is all 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 QF12, refer to the AC input power
cables to input circuit breakers QF01 to QF06.
