Connection

The units are operated at high voltages.
Only carry out connection work after disconnecting the voltage!
All work on the unit must only be carried out by qualified persons.
Non-observance of warning notices can result in death, severe personal injury or
considerable property damage.
Damage or destruction can result if the unit is incorrectly connected.
As the result of the dc link capacitors in the connected SIMOVERT Master Drives, the unit
still contains a hazardous voltage up to 5 min. after isolation. This is why it is only
permitted to open the unit after observing an appropriate waiting time.
The power terminals and control terminals may carry a voltage even when the motor is at
standstill.
When working on the open unit, pay attention to the fact that live parts are exposed. The
unit may only be operated with the front covers attached.
The user is responsible for ensuring that the common rectifier, converter, motor and other
units are installed and connected in accordance with the technical regulations recognized
in the country of installation and other regionally valid regulations. In doing so, particular
attention must be paid to cable dimensioning, fusing, earthing, deactivation, isolation and
overcurrent protection.
The power cables must be fixed in position mechanically outside the unit.
An external 24 V power supply is required for operation of the units (see Chapters 3.5 and 9.3).
Operational range of the unit: 20 V to 30 V.
