The oil filter unit and on-load tap-changer head are connected to each other by pipes. After each on-load tap-change, the insulating fluid is treated in the oil filter unit and transported back into the on-load tap-changer. A factory-set minimum run time of the pump [►Section 9, Page 44] ensures the necessary circula- tion of the entire insulating fluid, thus preventing deposits in the filter system. 14 OF 100 018/10 EN Maschinenfabrik Reinhausen GmbH 2021 3 Product description A necessary filter change is signaled by a pressure switch with signaling contact. A temperature-related and thus undesirable signal from the pres- sure switch can be suppressed on customer request. Further information on this is available in the section “Versions [►Section 3.3.2, Page 17]”.

Depending on the desired behavior upon reaching a working pressure of 3.6 bar/0.36 MPa and depending on the voltage supply, the oil filter unit can be supplied with or without a temperature switch / rod-type thermostat. Temperature Rod-type thermostat Note switch – – A necessary filter change is signaled by a pressure switch and a sig- naling contact once a working pressure of 3.6 bar/0.36 MPa is reached, regardless of whether the increase in working pressure is caused by a contaminated filter or by an increased viscosity of the in- sulating fluid due to temperature. For AC For DC If the temperature of the insulating fluid drops below 20 °C, the viscos- ity of the insulating fluid increases and, as a result, so does the work- ing pressure. A necessary filter change is also signaled in this case when 3.6 bar/0.36 MPa is reached, even though the increase in work- ing pressure is caused by the increased viscosity and not by a contam- inated filter. This message is suppressed by a temperature switch with alternating current or by a rod-type thermostat with direct current. – For AC and DC A rod-type thermostat installed in the base of the oil filter unit switches the oil filter unit to permanent operation as soon as the temperature of the insulating fluid falls below 0 °C. The oil filter unit remains in perma- nent operation until the temperature exceeds +5 °C. Table 4: Possible versions 3.3.3 Controller The electrical controller of the oil filter unit is either installed in the motor- drive unit or in a separate control cabinet. Controller in the motor-drive unit It is activated by a potential-free contact of the motor-drive unit. The run time is set in the factory using a time relay and can be switched to permanent op- eration using rotary switch S30. The controller is equipped with electrical safety equipment. A motor protec- tive switch with thermal and magnetic overcurrent trip is fitted per pump unit. Controller integrated in separate control cabinet It is activated by a potential-free contact of the motor-drive unit. The run time is set as follows: ▪ factory setting by time relay ▪ adjustable up to 24 hours by time switch ▪ can be switched to permanent operation using rotary switch S30 Maschinenfabrik Reinhausen GmbH 2021 018/10 EN OF 100 17  3 Product description The controller is equipped with electrical safety equipment.

Sealed packaging surrounds the packaged goods with plastic foil on all sides. Products that have also been dried are identified by a yellow label on the sealed packaging. In the dry state, delivery is also possible in a transport container. The information in the following sections should be applied as appropriate. 4.1.1 Suitability NOTICE Property damage due to incorrectly stacked crates! Stacking the crates incorrectly can lead to damage to the packaged goods. ► The outer marking on the packaging states if, for example, the on-load tap-changer or selector has been packed upright. Never stack these crates. ► General rule: Do not stack crates above a height of 1.5 m. ► For other crates: Only stack up to 2 equally sized crates on top of one an- other. The packaging is suitable to ensure undamaged and fully functional means of transportation in compliance with local transportation laws and regula- tions. The packaged goods are packed in a sturdy crate. This crate ensures that, when in the intended transportation position, the packaged goods are stabi- lized to prevent impermissible changes in position, and that none of the parts touch the loading surface of the means of transport or touch the ground after unloading. Sealed packaging surrounds the packaged goods with plastic foil on all sides. The packaged goods are protected from humidity using a desiccant. The plastic foil was bonded after the desiccant is added. 20 OF 100 018/10 EN Maschinenfabrik Reinhausen GmbH 2021 4 Packaging, transport and storage 4.1.2 Markings The packaging bears a signature with instructions for safe transport and cor- rect storage. The following symbols apply to the shipment of non-hazardous goods. Adherence to these symbols is mandatory. Protect against Top Fragile Attach lifting Center of mass moisture gear here Table 5: Shipping pictograms 4.2 Transportation, receipt and handling of shipments WARNING Danger of death or severe injury! Danger of death or serious injuries due to tipping or falling load. ► Only transport the crate when closed. ► Do not remove the securing material used in the crate during transport. ► If the product is delivered on a pallet, secure it sufficiently. ► Only trained and authorized persons may select the sling gear and se- cure the load. ► Do not walk under the suspended load. ► Use means of transport and lifting gear with a sufficient carrying capacity in accordance with the weight stated on the delivery slip. In addition to oscillation stress, jolts must also be expected during trans- portation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If a crate tips over, falls from a certain height (e.g. when slings tear) or is subject to an unbroken fall, damage must be expected regardless of the weight. Every delivered shipment must be checked for the following by the recipient before acceptance (acknowledgment of receipt): ▪ Completeness based on the delivery slip ▪ External damage of any type The checks must take place after unloading when the crate or transport con- tainer can be accessed from all sides. Maschinenfabrik Reinhausen GmbH 2021 018/10 EN OF 100 21  4 Packaging, transport and storage Visible damage If external transport damage is found upon receipt of the shipment, proceed as follows: ▪ Immediately record the identified transport damage in the shipping docu- ments and have this countersigned by the carrier. ▪ In the event of severe damage, total loss or high damage costs, immedi- ately notify the manufacturer and the relevant insurance company. ▪ After identifying damage, do not modify the condition of the shipment fur- ther and retain the packaging material until an inspection decision has been made by the transport company or the insurance company. ▪ Record the details of the damage immediately on site together with the carrier involved. This is essential for any claim for damages. ▪ Photograph damage to packaging and packaged goods. This also applies to signs of corrosion on the packaged goods due to moisture inside the packaging (rain, snow, condensation). ▪ NOTICE! If the product is delivered in sealed packaging, inspect this im- mediately. If the sealed packaging is damaged, do not under any circum- stances install or commission the packaged goods. Either re-dry the dried packaged goods as per the operating instructions, or contact the manu- facturer to agree on how to proceed. Failure to do so may result in dam- age to the packaged goods. ▪ Identify the damaged parts. Hidden damage When damages are not determined until unpacking after receipt of the ship- ment (hidden damage), proceed as follows: ▪ Make the party responsible for the damage liable as soon as possible by telephone and in writing, and prepare a damage report. ▪ Observe the time periods applicable to such actions in the respective country. Inquire about these in good time. With hidden damage, it is very hard to make the transportation company (or other responsible party) liable. Any insurance claims for such damages can only be successful if relevant provisions are expressly included in the insur- ance terms and conditions. 4.3 Storage of shipments Packaged goods dried by Maschinenfabrik Reinhausen Upon receipt of the shipment, immediately remove the packaged goods dried by Maschinenfabrik Reinhausen from the sealed packaging and store air-tight in dry insulating fluid until used if the packaged goods were not sup- plied in insulating fluid. Non-dried packaged goods Do not store combined filter cartridges for longer than 4 years. Otherwise the trouble-free function of the oil filter unit cannot be guaranteed. 22 OF 100 018/10 EN Maschinenfabrik Reinhausen GmbH 2021 4 Packaging, transport and storage Non-dried packaged goods with functional sealed packaging can be stored outdoors when the following conditions are complied with. When selecting and setting up the storage location, ensure the following: ▪ Protect stored goods against moisture (flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites and so on, and against unauthorized access. ▪ Store the crates on timber beams and planks as a protection against ris- ing damp and for better ventilation. ▪ Ensure sufficient carrying capacity of the ground. ▪ Keep entrance paths free. ▪ Check stored goods at regular intervals. Also take appropriate action after storms, heavy rain or snow and so on. Protect the packaging foil from direct sunlight so that it does not disintegrate under the influence of UV rays, which would cause the packaging to lose its sealing function. If the product is installed more than 6 months after delivery, suitable mea- sures must be taken without delay. The following measures can be used: ▪ Correctly regenerate the drying agent and restore the sealed packaging. ▪ Unpack the packed goods and store in a suitable storage space (well ven- tilated, as dust-free as possible, humidity < 50% where possible). 4.4 Unpacking shipments and checking for transportation damages ▪ NOTICE! Transport the packaged crate to the place where installation will take place. Do not open the sealed packaging until just before installation. If this is not done, damage to the packaged goods may occur due to inef- fectively sealed packaging. ▪ WARNING! When unpacking, check the condition of the packaged goods.Secure packaged goods in an upright crate from tipping out. If this is not done, the packaged goods may be damaged and serious injuries may result. ▪ Check completeness of supplementary parts on the basis of the delivery slip.

The control cabinet may only be connected to circuits that are equipped with an external and all-pole isolating device as close to the control cabinet as possible so that it can be fully de-energized if required (service, maintenance etc.). Furthermore, a control cabinet without its own overcurrent protective device may only be connected to circuits that are equipped with an external over- current protective device. The protective device must ensure protection against indirect touching. The protection recommended by Maschinenfabrik Reinhausen GmbH close to the control cabinet is 1.6 A C (3.0 A C is to be used in a heating circuit with additional heating and supply voltage < 127 V AC/DC). This is to be verified after installation by carrying out a measure- ment. Suitable equipment includes isolating devices in accordance with IEC 60947-1 and IEC 60947-3 (e.g. circuit breakers). When selecting the cir- cuit breaker type, the properties of the relevant circuits (voltage, maximum currents) must be observed. The following should also be noted during in- stallation: ▪ It must be easy for the operator to access the isolating device ▪ The isolating device must be labeled for the device and circuits to be iso- lated ▪ The isolating device may not be a part of the power line ▪ The isolating device may not interrupt the main protective conductor Unless specified otherwise, the connections for the supply circuits must have a conductor cross-section of at least 2.5 mm2 (14 AWG). Check applicable standards and directives to ensure that the specified minimum cross-section of the supply line is sufficient. The voltage supply for the control cabinet must be able to provide 5…7 times the nominal operating current of the motor-drive unit for one second. A maximum voltage tolerance of -20…+10% of the nominal voltage must be observed to avoid damage to the control cabinet. To electrically connect the oil filter unit and control cabinet, proceed as fol- lows: 1. Switch off the voltage supply. 2. Secure the voltage supply to prevent an unintentional restart. 3.
