Regenerative feedbackis deactivated and the bypass relay drops out. If the Line Module is not disconnected fromthe line supply when the EP terminal is de-energized, for example, because a line contactoris not installed, then the DC link remains charged.Death or serious injury can result when live parts are touched.• Neutralize the voltage in the DC link.NOTICEDamage to the drive electronics when switching the line contactor under loadWhen switching the line contactor (type according to the recommended selection) underload, then the contacts will be subject to premature wear. This can cause the contactor tomalfunction, with subsequent damage to the drive electronics.• Use a leading opening auxiliary contact or use a Voltage Sensing Module (VSM10).• If this is not possible, then avoid switching the line contactor under load.Artisan Technology Group - Quality Instrumentation ...
