COMMISSIONING vacon • 13588. COMMISSIONING8.1 SafetyBefore commissioning, note the following directions and warnings:Internal components and circuit boards of the frequency converter are live whenVacon NX Liquid-Cooled drive is connected to mains potential. Coming into contactwith this voltage is extremely dangerous and may cause death or severe injury.The motor terminals U, V, W and the DC-link/brake resistor terminals B–, B+/R+,R– are live when Vacon NX Liquid-Cooled drive is connected to mains, even if themotor is not running.The control I/O-terminals are isolated from the mains potential. However, the relayoutputs and other I/O-terminals may have a dangerous control voltage presenteven when Vacon NX Liquid-Cooled drive is disconnected from mains.Do not make any connections with the frequency converter connected to the mains.After having disconnected the frequency converter from the mains, wait until theindicators on the keypad go out (if no keypad is attached see the indicator throughthe keypad base). Wait 5 more minutes before doing any work on Vacon NX Liquid-Cooled drive connections. Do not even open the cover before this time has expired.Before connecting the NX Liquid-Cooled drive to mains, ensure the functionality ofthe coolant circulation and check the circulation for possible leaks.Before connecting the drive to mains make sure that the switchgear enclosuredoor is closed.9000.emf9000.emf9000.emf9000.emf13006.emf13006.emf13006.emfPhone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
