59Electrical installationWhat this chapter containsThis chapter describes the electrical installation procedure of the drive.WARNING! The work described in this chapter may only be carried out by a qualifiedelectrician. Follow the Safety instructions on the first pages of this manual. Ignoringthe safety instructions can cause injury or death.Make sure that the drive is disconnected from the mains (input power) duringinstallation. If the drive is already connected to the mains, wait for 5 min afterdisconnecting mains power.Checking the insulation of the assemblyDriveDo not make any voltage tolerance or insulation resistance tests (e.g. hi-pot ormegger) on any part of the drive as testing can damage the drive. Every drive hasbeen tested for insulation between the main circuit and the chassis (2500 V rms50 Hz for 1 second) at the factory. Also, there are voltage-limiting circuits inside thedrive which cut down the testing voltage automatically.Input cableCheck the insulation of the input cable according to local regulations beforeconnecting it to the drive.ohmPEMotor and motor cableCheck the insulation of the motor and motor cable as follows:1. Check that the motor cable is disconnected from the drive output terminals U2,V2 and W2.M 2. Measure the insulation resistances of the motor cable and the motor betweeneach phase and the Protective Earth by using a measuring voltage of 1 kV DC.The insulation resistance must be higher than 1 Mohm.Electrical installation
