The drive unit must be secured against being switched on accidentally (e.g. by locking the key switch
or by removing the fuses from the power supply).
Attach a notice to the ON switch stating clearly that work is in progress on the gear unit.
At the same time the complete installation must be without load, so that no danger occurs during

and bearings may be irreparably damaged by welding.
