Xantrex Technology XW4024-120/240-60 manual Torque Values for the XW Series Inverter/Charger

Inverter/Charger Installation

Terminal covers	Color-coded snap-on DC terminal covers are provided to prevent accidental contact with
	the terminals. Terminal covers are required for all installations, even if a XW Conduit Box
	is used. It is also recommended that the shank of the ring terminals (cable lugs) be covered
	with heat shrink or some other form of insulation.
	Table 2-2Recommended Battery Cable Size Versus Length
	Inverter Model	Up to 5 Feet (1.5 m) (90°C wire)	Up to 10 Feet (3 m) (90°C wire)
	XW4024	#4/0 AWG (120 mm2)	#4/0 AWG (120 mm2)
	XW4548	#2/0 AWG (70 mm2)	#4/0 AWG (120 mm2)
	XW6048	#4/0 AWG (120 mm2)	#4/0 AWG (120 mm2)

Important: The NEC/CEC requires both overcurrent protection and a disconnect switch for residential and commercial electrical systems. These items are not supplied as part of the inverter, but are included in the XW Power Distribution Panel.
