WARNING
The units are operated at high voltage levels.
All connection work must be carried out in the no-voltage condition!
Only qualified personnel who are familiar with all the safety instructions in these operating
instructions, as well as the assembly, installation, operating, and maintenance instructions, -
should carry out work on these units.
Non-observance of these warnings can result in death, serious personal injury, or substantial
property damage.
Connecting the unit incorrectly can lead to it being damaged or destroyed.
The units may be connected to a line supply with a residual current operated circuit breaker if a
universal current sensitive device is being used, which in the case of a ground fault, can also
detect a DC component in the fault current. It is recommended to use a residual current operated
circuit breaker with a response current ≥300 mA, which means that it is not suitable for protecting
personnel. If you have additional questions, please contact Technical Support.
Even when the motor is stationary, power terminals and control terminals can still be at a certain
voltage.
Even after being disconnected from the power supply, the snubber capacitors in the converter
unit can still be at a dangerous voltage level. For this reason, the unit should not be opened until
an adequate period of time has elapsed.
When handling the unit while it is open, remember that live parts are exposed. The unit must
only be operated with the front covers provided by the factory in place.
The user is responsible for ensuring that the SIMOREG CCP, the motor, converter unit and other
devices are installed and connected in accordance with the recognized technical rules in the
country of installation and applicable regional regulations. Special attention should be paid to
cable dimensioning, fuses, grounding, shutdown, disconnection, and overcurrent protection.
The units described here control rotating mechanical equipment (drives). Failure to follow these
operating instructions may result in death, serious physical injury, or extensive material damage.
Perfect, safe and reliable operation of the units is conditional upon them having been
professionally transported, stored, mounted, and installed, and having been carefully operated
and maintained.
Also observe all of the safety instructions in the converter unit operating instructions.
Note
Please observe the installation instructions for EMC-compliant design of drives in Chapter 6.1 of the
operating instructions of the basic SIMOREG DC-MASTER or SINAMICS DCM unit.
