2.2 Electrical hazards
WARNING: HAZARDOUS VOLTAGES
Risk of electric shock. Do not touch parts at high electric voltages, there is the risk of
suffering severe injuries by an electric shock. Covers marked with this symbol must
only be opened by trained electricians after having reliably de-energised (Lockout/
Tagout) the equipment. Observe the national regulations for example - EN 50110-1
for Europe.
WARNING: AUTOMATIC RESTART
Risk of injury or damage to the equipment. After a mains power failure, the pump will
operate automatically again. This also applies in the case of an emergency shut-
down. To prevent the pump from operating automatically, the pump must be
integrated with a control arrangement such that it can only be switched on manually
after the mains power has returned.
▪ Always operate the pump with a properly connected protective earth
conductor and make sure that the motor terminal box is closed.
▪ Lay electric feed lines so that there is no risk of tripping.
▪ Lay the connecting lines so that the connecting lines do not get
damaged. Protect the lines against humidity and contact with fluids.
Avoid thermally stressing the lines by unfavourable laying. Provide
strain relief for the connecting lines so that the plugs and the line
connectors are not subjected to excessively high mechanical stresses.
▪ Take appropriate precautions to make sure that the pump does not
start while laying electric feed lines.
2.3 Thermal hazards
WARNING: HOT SURFACE
Risk of burn. During normal operation, the pump surface temperature can reach
above 70 °C (158 °F). There is a risk of getting burns. Note the symbols on the pump
indicating the hazards. If the pump is hot, wear the required protective clothing. All
the work must be done using protection gloves if the pump is still warm.
▪ Handle the pump only after venting and after it cools down.
▪ Do not remove the oil-fill or oil-drain plugs while the pump is operating.
There is a risk of suffering burns. Always wear protective gloves and
protective goggles for protection against the oil.
▪ Note the warning information on the housing surface. If these warning
notices have been removed, covered or obstructed, include
corresponding additional warning information.
2.4 Hazards caused by materials and substances
WARNING: HAZARDOUS SUBSTANCES
Risk of injury. When pumping toxic, chemical, radioactive and corrosive gases as well
as pyrophoric substances, you must comply with the national and international safety
regulations and guidelines. If such gases or substances are to be pumped, consult us
first for the suitability of the pumps for special applications.
