Installing the fuse housing

A fuse housing is now installed on a number of jib cranes. The scope of delivery indicates whether this housing needs to be installed.

Three fuses are placed in the housing, which are used to fuse the crane.

Terminal for protective conductor

Fuse isolating link

 

*   Attach the connection cable from the mains power supply to the fuse isolating link.

*   Attach the connection cable to the trolley power supply on the fuse isolating link.

*   Connect both protective conductors to the terminal for protective conductors.

*   If necessary: connect both neutral conductors to the terminal for neutral conductors.
