The cable must not be bent or crushed on the direct exit of the cable screw joint. A minimum
bending radius r≥4x (static steady), r≥5x (dynamic) cable diameter must be maintained. The
cable must be routed in a way that tensile stress on the conductor or connection(s) is
prevented.
Pay attention to the following when wiring:

Check that the wiring is correct before commissioning the system. If the measured open
circuit voltage differs from the specifications, then there is a wiring fault. Ensure that the
polarity is correct.
