Electrical connection                                                        Ventilation

User is recommended to use a cable of min temperature withstand           Capacitors, contactors, fuses and electrical connections

capacity of90°C                                                                                   generate heat dissipation(about 2.5 W/kvar total or 8 W/kval

Use flexible cables                                                                                with series reactors)

Paralleling of the capacitor should not be done at the capacitor                 Specific precautions must be taken in order not to exceed

terminals as shown in the figure. Ensure that the paralleling is done          temperature values of -25 C/+55C(class D)category around

at contactor side and two separate cables are coming to the capacitor       the capacitors inside the cubicle. (refer to"Installation Guide"for

terminals from contactor(See figure with "Right"connection)                     moreinformation)

                                                                                                          The airflow inside the cubicle must go from bottom to top
