<Attentions when Connecting the Power Supply Wiring>
1 Whenconnectingtheterminalblockusingstranded
wire,makesuretousetheroundcrimp-styleterminalfor
connectiontothepowersupplyterminalblock.Placethe
round crimp-style terminals on the wires up to the covered
part and secure them in place.
2 Whenconnectingtheterminalblockusingasinglecorewire,
