You must remove three terminal block covers for the 4000 W DC-input power supply. The
left-side inner terminal block cover has two securing screws, and the right-side inner terminal
block cover has one securing screw.
You must install the plastic insulators that are shipped with the power supply.
Be sure to place a plastic insulator over the smaller terminal block, even if you are not attaching
DC-input wires to it; this action ensures that the plastic insulator is available for future use.
