The installation must always be designed and made according to applicable local laws and regulations. ABB does not assume any liability whatsoever for any installation which breaches the local laws and/or other regulations. Furthermore, if the recommendations given by ABB are not followed, the drive may experience problems that the warranty does not cover.
Keep the cable as short as possible in order to minimize the radiated emissions. EMC compliance of the complete installation ■ ABB has not verified that the EMC requirements are fulfilled with an external DC cabling. The EMC compliance of the complete installation must be considered by the customer (or the system integrator).
Electrical installation 25 Electrical installation Contents of this chapter This chapter contains electrical safety precautions, instructions for measuring the insulation of the external power cabling, connection diagrams and instructions for connecting the external power cabling and control cabling.
26 Electrical installation Electrical safety precautions These electrical safety precautions are for all personnel who do work on the drive, motor cable or motor. WARNING! Obey these instructions.
