Notes on Installation
Maximum allowed line length to external braking and charging resistor: 5 m
Twist unshielded lines.
Danger by insufficient installation!
Protect the lines with the appropriate fusing elements in the supply feeder.
For the connection lines at X9, use at least the cross section of the lines for
mains connection at X3.
