Grounding lug—A two-holed standard barrel lug that supports up to 6 AWG wire.
Grounding nuts—Two M6 nuts.
Grounding wire—This wire should be sized to meet local and national installation requirements. For
U.S. installations, you must provide a 6 AWG copper conductor. For installations outside the U.S.,
consult your local and national electrical codes. The length of the grounding wire depends on the

Wire-stripping tool to remove the insulation from the grounding wire.
Number 1 Phillips screwdriver.
Crimping tool to crimp the grounding wire to the grounding lug.
Power cables—one for 3-kW output power or two for 6 kW output power. Each cable is 4.6 meters
(15 feet) in length with one plug at one end and terminal lugs on each of four inputs.
Power cables that connect the PIU to the power source. These cables need to be sized to meet local
and national electrical codes.
