• Before starting up, the pump must be integrated into the equipotential bonding, i.e. equipotential
bonding of the pump tube with the tank, equipotential bonding of the motor with the tank or with
the pump tube if pump tube and drive motor are not conductively connected with each other. The
container must be grounded separately if not already given by the type of installation. Establish
equipotential bonding between container to be emptied and filled, e.g. with earthing lead or
by conductive ground which is conductively connected with both containers. If necessary, other
accessories must also be integrated to the equipotential bonding (
