Crane transport

WARNING

Risk of injury! • Pay attention to the weight!

• Use means of transport suited to the requirements and load carrying capacity!

• Suspend the SION® vacuum circuit-breaker in the withdrawable frame from a crane only in the inserted state!

For crane transport, especially of heavy circuit-breaker versions, we recommend use of a work-shop crane, for example the Compac CC055 or CC055 junior from the following company: KSM ServiceTechnik GmbH & Co. KG Bosch contract wholesaler Robert-Koch-Strasse 8 21423 - Winsen / Luhe Germany www.ksm-wakon.de

Storage

CAUTION

Damage! If the packing has been opened, make sure during storage that the SION® vacuum circuit-breaker is in the following state in the with-drawable frame:

• OPEN (OFF) position

• Closing spring relaxed Until it is installed, store the withdrawable module with the SION® vacuum circuit-breaker (and earthing switch) in closed, dry, well-ventilated and, as far as possible, dust-free rooms in its foil (dense packing for overseas trans-port). Relative humidity in storage rooms should be less than 60 %. The withdrawable module with the SION® vacuum circuit-breaker (and earthing switch) can be stored and trans-ported outside the context of its normal operating conditions within the limit temperature range of -40 °C to +55 °C in closed foil (tight and closed packing). As the stacking quantity depends on the weight of the packing unit, the load-carrying capacity of the packing and its overall height, no more than three packing units should be stacked on one another. The weight of the packing unit is documented on the delivery note. The withdrawable module with the SION® vacuum circuit-breaker (and earthing switch) for overseas transport are packed with VCI foil. The VCI foil creates a protective atmosphere that safeguards the circuit-breaker against cor-rosion. The protective atmosphere evaporates without residues after a short time when the VCI foil is removed, so the circuit-breaker can be used directly out of the packing without any subsequent treatment.

Maintenance

Maintenance

DANGER

Risk of injury! Working on the withdrawable module with the SION® vacuum cir-cuit-breaker activated/deactivated and with the spring energy store charged can lead to mortally serious injuries. • Disconnect the operating voltage and switch off the low-

voltage supply before performing maintenance work!

• Close and open the vacuum circuit-breaker manually. By doing so, you will make sure that the circuit-breaker is open and that the spring energy store is relaxed.

• Close and open the vacuum circuit-breaker manually. By doing so, you will make sure that the circuit-breaker is open and that the spring energy store is relaxed.

Maintenance

General The SION® vacuum circuit-breaker requires no maintenance under normal conditions. We nevertheless recom-mend a regular visual check. For optimum insulation, the insulating parts must be clean: • Switch off the low-voltage supply before performing maintenance work!

• In the event of heavy soiling, wipe off all other parts with a lint-free cleaning cloth.

• Grease the contact faces to busbars with Vaseline.

Maintenance

Product liability The manufacturer's product liability will be rendered null and void if at least one of the following criteria applies: • Original Siemens spare parts are not used.

• Fitters performing replacement have not been trained and certified by Siemens PTD M C.

• Parts have been incorrectly fitted or adjusted.

• Settings are not made in accordance with Siemens specifications.

• After installation and setting, no final check is performed with a tester approved by PTD M C including docu-mentation of the test results.

So that documentation can be kept complete, it is important for measurement results to be submitted to PTD M C Q.

Service For details of contacts for service work, consult Siemens PTD Services • Tel.: +49 180/5247000

Disposal

If possible, the materials of the withdrawable module should be recycled. Disposal of the withdrawable module with minimum environmental impact is possible on the basis of existing legal regulations. The components of the withdrawable module, of the SION® vacuum circuit-breaker and of the installation accesso-ries can be recycled as mixed scrap, although dismantling to the maximum extent possible into sorted scrap and mixed scrap residues is more environmentally sustainable. Electronic scrap must be disposed of in accordance with applicable regulations. The ® withdrawable module with the SION vacuum circuit-breaker consists of the following materials: • Steel (partly phosphatized, galvanized and yellow chromated)

• Copper (partly silver-plated)

• Aluminum (partly silver-plated)

• Plastics (polyamide, polyester, polycarbonate, ABS-PC mixture; partly fiberglass-reinforced)

• Rubber materials

• Ceramics

• Lubricants

When delivered by Siemens, the circuit-breaker does not contain any hazardous substances in terms of the haz-ardous substances regulations applicable to the territory of the Federal Republic of Germany. For operation out-side the Federal Republic of Germany, the applicable local laws and regulations must be complied with.
