The connections for the protective earth conductor ([PE]) of the connector must be connected to the protective earth conductors of the connected motors. Motor 1/5 Motor 2/6 Motor 3/7 Motor 4/8...
Starting up Starting up CAUTION! Risk of injury due to movable loads in the range of electric chain hoists. If people are in the work area, the loads moved by the electric chain hoists can cause injuries. Ensure that there are no persons in the work area of electric chain hoists as long as loads are being moved.
Page 15
Starting up NOTICE! Damage to the device and connected electric chain hoists due to impulse operation! Repeated, momentary presses of the [RUN] button can damage the device and the connected electric chain hoists. Always press [RUN] for at several seconds, never several times in a row. Starting up the device Ensure the following: There is nobody in the work area of the electric chain hoists.
