2.2.4 Explanations of voltage classes
NX_5 = 380 - 500 VAC drives -> DC link voltage = 465 - 800 VDC
NX_6 = 525 - 690 VAC drives -> DC link voltage = 640 - 1100 VDC
NX_8 = 525 - 690 VAC drives -> DC link voltage = 640 - 1200 VDC
2.2.4.1
IT networks
The grounding of input capacitors made by default with the grounding screw at terminal X41 of the
bus board in all drives is imperative in all variations of TN/TT networks. Should a drive originally
purchased for TN/TT networks be used in an IT network, the screw at X41 must be removed. It is
strongly recommended that this be done by Danfoss personnel. Ask you local distributor for more
information.
