8.4-8 Compendium Motion Control SIMOVERT MASTERDRIVES
8.4.3 Connecting
The SIMOVERT MASTERDRIVES are operated with high voltages.
Any work on the unit may only be carried out by qualified personnel.
If this warning is ignored, serious bodily injury or considerable damage
to property can occur as a consequence.
Because of the DC link capacitors, there continues to be dangerous
voltage in the unit until up to 5 minutes after disconnection. The unit
must not therefore be opened until at least this length of time has
expired.
Even when the motor is at a standstill, the power terminals and the
control terminals can carry voltage. During work on the converter, it is
to be disconnected from supply.
When handling the opened converter, it must be kept in mind that live
components are exposed.
The CBC contains electrostatically sensitive components. These
components can very easily be destroyed by improper handling.
