Use a shielded motor cable in order to guarantee error-free operation of the
controller. In addition, no other conductors except the motor connection may be
included in this line.
In the case of drive units with an electronic brake, ensure that the brake is
equipped with adequate suppression. We recommend the use of RC-elements for
interference suppression purposes.
We recommend for a motor cable length of approx. 10 m the usage of a motor cable of
a leakage capacitance (wire/shield) of up to or less than 150 pF/m. If the Earth Leakage
Circuit Breaker (RCD) will be triggered unintentionally, we recommend setting the
switching frequency to a suitable fixed frequency of the door controller with the
parameter P.160. The optimum setting can be determined by measuring the leakage
current. The switching frequency with the lowest leakage current must be set.
The 30 mA Type B RCD cannot be used with this door controller. A 300 mA type B
earth leakage circuit breaker must be used here.
