4.9.2 Installing the AC Input Power Cable of the APM30The APM30 obtains AC input power through the AC input power cable.

ContextWhen the 110 V AC dual-live-wire input is used, the L1 wire connects to AC terminal L andthe L2 wire connects AC terminal N. When the 220 V AC single-phase three-wire input is used,the L wire connects to AC terminal L, the N wire connects AC terminal N, and the PE wireconnects to the grounding terminal. This task takes the 220 V AC to 240 V AC single-phasethree-wire input as an example.
