During operation they can have live energized uninsulated parts, moving parts, as well as hot surfaces. Care should be taken to ensure correct and safe operation in order to minimize risk to personnel and equipment. All work involving this product, installation, start up as well as mainte nance may only be performed by qualified electrical technical person nel. According to this manual qualified means: those who are able to recognize and acknowledge the possible dangerous conditions based on their training and experience and those who are familiar with the relevant standards and installation codes as well as the field of power transmission. AC motor controls and servo drives must be protected against physical damage during transport, installation, and use. Components or covers must not be bent or deformed as this may decrease insulation distanc es inside the unit resulting in an unsafe condition. On receipt of the unit visual damage should be reported immediately to the supplier. DO NOT ATTEMPT TO POWER UP A UNIT WITH VISIBLE PHYSICAL DAMAGE. This unit contains electrostatically sensitive ponents which can be destroyed by in correct handling. For that reason, disassembly of the unit or contact with the ponents should be avoided. Before any installation and connection work can be done the supply voltage must be turned off and locked out. After turning off the supply voltage, dangerous voltages may still be present within the unit as the bus capacitors discharge. Therefore it is necessary to
