subjected to the splashing of oil or other hazardous liquids. Doing so may
result in re, electric shock or injury.
yAssign qualied personnel the task of installing, wiring, operating/
controlling, inspecting and troubleshooting the product. Failure to do so
may result in re or injury.
yDo not transport, install the product, perform connections or inspections
when the power is on. Always turn the power o before carrying out these
operations. Failure to do so may result in electric shock.
yProvide a measure to retain the position of the movable part of the
equipment when the product is used in a vertical application. The motor
loses its holding torque when the power is cut o. Without appropriate
measures the movable part will descend, resulting in injury or damage to
the equipment.
yInstall the motor in the enclosure to avoid contact with the hands, or
provide sucient earthing. Failure to do so may result in electric shock.
yConnect the product correctly and securely according to the wiring
diagram. Failure to do so may result in re or electric shock.
