AC Wiring
1.
Prepare AC cables: Prepare six 35 ~ 50 mm
2
600V cables for AC wiring. The PCS supports 3-
phase/4-wire connection type AC wiring with L1, L2, and L3 phase and Neutral terminals, and
each phase terminal requires two cables to connect. Attach the AC cables to the two-hole lugs,
and use a thermal casing to prevent the exposure of the naked part.
2.
Remove the protective cover of AC terminals: Remove the protective cover in front of the
AC terminals as the figure shown below. There are three labels indicating the phaseof the
terminals: “L1” for L1 phase, “L2” for L2 phase, “L3” for L3 phase, and “N” for Neutral phase.
Each phase terminal provides a back-to-back connection way for connecting two AC cables.
3.
Connect AC cables to AC terminals: Loosen the hex socket screws of the AC terminals by
Allen wrench, then lead the AC cables with two-hole lugs through the AC cable glands into the
PCS, connect and secure these cables to the relevant “L1”, “L2”, “L3” and “N” terminals.
4.
Reinstall and secure the AC protective cover.
