Please follow the following safety instructions during all repair work on the crane:

─     Switch off the mains switch. Secure the switch to ensure it cannot be turned back on accidentally.

─     Unplug the mains disconnector plug from the socket on the crane panel. Secure the socket with a padlock to ensure it is not plugged back in accidentally.

─     Use suitable lifting platforms and fall protection equipment.

─     Adequately cordon off the operating range around the lifting platform.

─     Switch off any other cranes using the same crane track or cranes working above or below the crane undergoing maintenance. Secure the switches to ensure they cannot be turned back on accidentally. Otherwise, other cranes could overturn the hoisting platform or crash into the crane undergoing maintenance.

─     Notify personnel in the area that maintenance work will be performed.

─     Only trained electricians should work on the crane electrical system!

─     Even after the emergency stop button has been pressed, life-threatening high voltages are still present in the panels.

These safety instructions apply especially to ABULiner:

─     Danger of burning! The braking resistance and frequency converter become hot during operation. Allow the braking resistance and frequency converter to cool down before working on the crane.

─     Parameters and settings in the frequency converter may only be changed by persons trained by ABUS using PC software or control panel (optional).

─     Should changes to the circuitry of the crane be necessary, be sure to contact ABUS Service. See ABUS Service.

─     Before working on the crane, disconnect the power line and wait at least four minutes until the voltage has dissipated.

─     Do not open the housing of the frequency converter.
