obstacle-free paths.
Before moving the contactor truck, check the path and the ramps.
Keep the shunting area, paths and the ramps free of obstacles and dry.

floor in the travel area.
Move the contactor truck only slowly and constantly.

Maloperation
A contactor truck may only be operated in a panel if the HV HRC fuse-links
installed match the particular panel version. However, there is no coding on the
contactor truck to prevent inserting it in a panel not suitable for the particular
contactor version.
Do absolutely observe the rated currents of the HV HRC fuse-links.
