    Cables must not be connected or disconnected, nor signal tests carried out, while the power is switched on. The Varispeed L7 DC bus capacitor remains charged even after the power has been switched off. To avoid an electric shock hazard, disconnect the frequency inverter from the mains before carrying out maintenance.

  • Page 9

    The DC bus capacitors can remain live for about 5 minutes after the inverter is disconnected from the power. It is therefore necessary to wait for this time before opening its covers. All of the main circuit terminals may still carry dangerous voltages.

    The inverter measures the current level or torque reference S2-05 sec. after the speed-agree condition (acceler- ation finished) for the time set in S2-06 and calculates the average value to estimate the load. This value is used for the calculation of slip which is added to the speed reference at leveling speed (see 6.14).
