9 Operation
9.1 Safety notes
WARNING
Hazard from electrical voltage
›
The device may only be operated by people
–
instructed in the function and risks,
–
who have understood them and are in a position to react accordingly.
›
Ensure that children do not operate the device or play with it without supervision.

9.2 Operating conditions
•
Do not operate the Multibox in an explosion-capable atmosphere.
•
During operation, touching the rotor may not be possible.
•
Safety components may not be circumvented or put out of function.
•

–
The controls may not permit any extreme switching operations.
•
In cases of speed control via frequency inverters, make sure that voltage peaks on the motor terminals must be lower than 1000 V
and voltage rise velocities lower than 500V/µs (IEC 34-17).
–
If the motor line is long, use an output filter between the frequency inverter and the motor.
•
If the operational leakage current of 3.5 mA is exceeded, the conditions with a view to earthing pursuant to DIN VDE 0160/5.88.
ART.6.5.2.1 are to be fulfilled.
•
Noise development can be minimised by use of a noise filter.
