NOTICE Material damage Risk of damage to or destruction of the backstop and/or the gear unit through incorrect direction of rotation.
5.8.1 As a rule the fan is fitted on the highspeed shaft of the gear unit and is protected from accidental contact by an airguide cover. The fan sucks air through the grid of the airguide cover and blows it by way of its air ducts on the side along the gearunit housing.
5.8.2 Cooling coil The gear unit can be fitted with a cooling coil in the oil sump. Cooling water is supplied to the cooling coil by way of a water connection. The operator must ensure this. Either fresh water, sea water or brackish water can be used for cooling purposes.
5.8.3 Separate or external oilsupply system It is possible to use an oilsupply system which is separately supplied by Siemens or an external system to ensure cooling of the oil. Note Be sure to observe the operating instructions of the oilsupply system for operation and maintenance.
5.10 Heating At low temperatures it may be necessary to preheat the gearunit oil before switching on the drive unit or even during operation. In such cases the use of heating elements is possible. The heating elements convert electrical energy into heat which is transferred to the surrounding oil. The heating elements are located in protective tubes inside the housing, thus making it possible to replace the heating elements without draining off the oil.
5.11 Heating element in "Ex"version If heating elements are designed to be explosion-proof, the gear unit is additionally equipped with oil-level monitoring by means of an oil-level limit switch. This monitoring system checks the oil level in the gear unit for immersion of the heating elements (see item 5.11.1).
5.13 Oiltemperature monitoring system The gear unit can be fitted with a temperature monitor for measuring the oil temperature in the oil sump. In order to measure the temperatures and/or temperature differences, the temperature monitor should be connected to an evaluating device provided by the customer. If the gear unit is designed as an appliance of category 2 in conformity with Directive 94/9/EC, it is, as a standard, equipped with a Pt 100 resistance thermometer, a thermoelement or with a temperature control for measuring the oil temperature in the oil sump.
5.14 Oillevel monitoring system The gear unit may be fitted with an oillevel limit switch for monitoring the oil level. The oillevel monitoring device has been designed for checking the oil level when the gear unit is at a standstill, prior to operating start.
The gear unit may also be set up for temperature monitoring at the bearing points. The gear unit is then equipped with tapped holes for fitting Pt 100 resistance thermometers. For this version Siemens must be consulted.

5.16 Changeover The gear unit can be fitted with a clutch as an option. The gear unit can be changed for two speeds. Changeover is done manually. NOTICE Material damage Risk of destruction of the gear unit or gearunit components. The shifting operation may only be done with the motor at a standstill and while the load hook is lying on the floor or with the brake on the output side switched on.
When transporting the gear unit, observe the notes in section 4, "Transport and storage". Fitting work must be done with great care by authorised, trained and qualified personnel. Siemens cannot be held liable for damage caused by incorrect assembly and installation.
The products supplied are listed in the dispatch papers. Check immediately on receipt to ensure that all the products listed have actually been delivered. Parts damaged and/or missing parts must be reported to Siemens in writing immediately. • Remove packaging material and transporting equipment and dispose of in accordance with regulations.
