DO NOT assemble the connector with wet or dirty hands.
Always make sure that all locking connectors are fully engaged and locked. Otherwise faulty
connetions can result in arcs, electrical shock, and equipment damage.

Do not bend the cable directly behind the contact point. A minimum bending radius of 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 avoided.

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.
