Electrical devices and lines normally generate electromagnetic fields. These fields can negatively affect other devices and cause malfunctions. To best avoid such disturbances, certain basic principles must be observed when working with electrical equipment.

For any electrical work performed on the crane:

In order for the crane to operate without faults, all electrical components and all connection cables must be installed by professionals.

Observe the following points amongst others:

─     Do not lay signal lines together with current-conducting lines.

─     With frequency converters: guide connection cables for braking resistance and connection cables for motors through the cable fittings in the panel and lay them in a direct path to the frequency converter.

─     Lay the shields of shielded cables over a wide area and earth them.

─     Do not twist, braid or solder shields. Instead, use the supplied installation material.

─     Earth the unused wires of cables in the panel.
