Table 4-2 ISO fault

ISO fault

	Causes	Damaged, worn-through cables (loose, buffeted by
		wind)
		Cables damaged by animals
		Water in junction box
		Damaged insulation and ingress of water to cable
		duct
		Defective power unit
		Bending device defective
		Defect in PV module (damaged)
		High air humidity (causes high leakage currents)
	Diagnostics	Check the sensitivity (limit values) of the insulation
		monitor using a decade resistor
	Measures	Repair the cabling
		Empty and dry out the junction boxes and / or cable
		ducts
		Repair / replace the drive
