1. 2 Safety instructions The Vacon NX frequency converter is meant for fixed installations only Do not perform any measurements when the frequency converter is connected to the mains After disconnecting the frequency converter from the mains wait until the fan stops and the indicators on the keypad go out if no keypad is attached see the indicators on the cover Wait 5 more minutes before doing any work on Vacon NX connections Do not even open the cover before this time has expired Do not perform any voltage withstand tests on any part of Vacon NX There is a certain procedure according to which the tests shall be performed Ignoring this procedure may result in damaged product Prior to measurements on the motor or the motor cable disconnect the motor cable from the frequency converter Do not touch the IC circuits on the circuit boards Static voltage discharge may damage the components Before connecting the frequency converter to mains make sure that theVacon NX front and cable covers are closed ALIMAK 34849 1 01 A Earth Ground 1 3 Earthing and earth fault protection The Vacon NX frequency converter must always be earthed with an earthing conductor connected to the earthing terminal The earth fault protection inside the frequency converter protects only the converter itself against earth faults in the motor or the motor cable Due to the high capacitive currents present in the frequency converter
