The motor cable terminals of the drive are at a dangerously high voltage when mains power is applied, regardless of motor operation.
There can be dangerous voltages inside the drive from external control circuits even when the drive mains power is shut off. Exercise appropriate care when working on the unit. Neglecting these instructions can cause physical injury or death.
The material in this chapter must be studied before attempting any work on the filters.
In addition to the safety instructions given below, read the complete safety instructions of the specific drive (presented in the Hardware Manual accompanying the drive) you are working on.
If work is to be done on the sine filter capacitors, the voltage over the capacitors must be measured to ensure they are discharged.

General safety instructions
WARNING! All electrical installation and maintenance work on the drive should be carried out by qualified electricians.
The drive and adjoining equipment must be properly earthed.
Do not attempt any work on a powered drive. After switching off the supply voltage, always allow the intermediate circuit capacitors 5 minutes to discharge before working on the frequency converter, the motor or the motor cable. It is good practice to check (with a voltage indicating instrument) that the drive is in fact discharged before beginning work.
Sine filter safety instructions
The capacitors of the sine filter are discharged via the drive. Wait 5 minutes after switching off the supply voltage before starting work on the filter. The voltage between each output terminal of the drive (U2, V2, W2) and earth must be measured with a multimeter (impedance at least 1 megaohm) to ensure that the drive is discharged before beginning work.
