WARNING

SIMOVERT MASTERDRIVES units are operated at high voltages.

 

All work carried out on or with the equipment must conform to all the

 

national electrical codes (VBG 4 in Germany).

 

Maintenance and service work may only be executed by qualified

 

personnel.

Only spare parts authorized by the manufacturer may be used. The prescribed maintenance intervals and also the instructions for repair and replacement must be complied with.

Hazardous voltages are still present in the drive units up to 5 minutes after the converter has been powered down due to the DC link capacitors. Thus, the unit or the DC link terminals must not be worked on until at least after this delay time.

The power terminals and control terminals can still be at hazardous voltage levels even when the motor is stationary.

If it is absolutely necessary that the drive converter be worked on when powered-up:

Never touch any live parts.

Only use the appropriate measuring and test equipment and protective clothing.

Always stand on an ungrounded, isolated and ESD-compatible pad.

If these warnings are not observed, this can result in death, severe bodily injury or significant material damage.
