W A R N I N G : E l e c t r i c S h o c k
High voltages can cause life-threatening currents in the body and injury from elec-
tric shock. Allow only trained and qualified electrical technicians to work on the
electrical system. Before any electrical work, disconnect the unit from the power
supply and lock to prevent unauthorized persons switching it on.
Do NOT use excessive force. Forces that are exerted on the load cell from outside
when attaching and removing the weigh bin load cell may damage the very sensi-
tive load cell.
