Safety instruction
!
CAUTION
Danger of electrical overvoltage!
•
Connect a charging capacitor with at least 4700 µF!
•
An operating voltage higher than the admissible operating voltage (see the "Technical data of
motor" section) destroys the output stage!
•
Mixing up the connections can destroy the output stage!
•
Never connect or disconnect lines when live!
•
The supply voltage must be selected so that it neverexceeds the admissible operating voltage of
the motor. In particular, interferences by other consumers or by voltages induced by the motor
must be considered, and if necessary a voltage must be selected that offers an adequately high
safety reserve.
Voltage source
The operating or supply voltage is delivered by a battery, a transformer with rectification and filtering, or
better a switch-mode power supply.
Interference suppression and protection measures are required when a DC power supply line with
a length of >30 m is used or the motor is used on a DC bus. An EMI filter is to be installed in the DC
supply cable with a small as possible distance to the motor controller/motor.
Long data or supply lines are to be routed through ferrites.
