Installing the Bowden wire
Bowden wires must be installed in a way that they are not bent excessively (large bending
radii).
Secure Bowden wires by means of cable ties .
Minimum permissible bending radius: R = 50 mm. This bending radius is only permitted a
maximum of six times for each Bowden wire. The remaining bending radii should be as large
as possible.
The total bending angle across the length of the Bowden wire must not exceed 360°.
Risk of personal injury and/or equipment damage
If a mechanical Circuit Breaker interlock is installed, two or more Circuit Breakers must not
be closed simultaneously by electrical or mechanical means.
The delay between the close commands must be at least 100 ms.
