nit. The lubricant is fed and distributed to the individual lubricating points through pipe system located on the inside of the gear unit. The nozzles and orifice plates used on it have large free cross-sections which have no tendency to blocking. For detailed illustration of the gear unit and possibly the oil-supply system, refer to the drawings in the documentation. WARNING Serious physical injury from defective pressure monitors is possible. Two pressure monitors must be fitted in the oil feed line on the gear unit. Interlocking of these pressure monitors: WARNING at 1.3 bar SHUTDOWNof the input drive at 1.0 bar Note When operating and servicing the components of the oil-supply system, observe the operatinginstructions of the components.For technical data and control information, refer to the data sheet and/or the list of equipment. 5.3 Shaft seal Labyrinth seals on both shaft outlets on the input side prevent oil from escaping the housing and dirt penetrating to the inside of the gear unit. Labyrinth seals prevent wear and tear on the shaft, are maintenance-free and ensure favourable temperature characteristics. As the housing is designed to be open at the output and the output pinion engages in the girth gear direct there, no shaft seals are required here. However, the gear-unit housing must be tightly attached to the girth gear cover. NOTICE Property damage Deficient lubrication is possible by oil leakage on the gear unit. For reliable operation, labyrinth seals require stationary, horizontal positioning away from dirty waterand high dust concentrations. Overfilling of the gear unit can cause leakage, as can oil with high foam content. 1 / 5BA 5 en 0/2.4 Terminal diagram If necessary, 2 pressure monitors, 2 resistance thermometers and/or 1 displacement gauge can be fitted on the gear unit and wired in terminal box. In this case the following description applies. If only one of the devices mentioned above is fitted and wired in the terminal box, only part of
