  • Page 18: Packaging, Transport And Storage

    4 Packaging, transport and storage 4.1 Purpose The packaging is designed to protect the packaged product during transport, loading, unloading and during periods of storage in such a way that no detri- mental changes occur. The packaging must protect the goods against per- mitted transport stresses such as vibration, knocks and moisture (rain, snow, condensation).

  • Page 19: Markings

    4.3 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 Fragile Attach lifting Center of mass moisture gear here Table 4: Shipping pictograms...
  • Page 20 Visible damage If external transport damage is found upon receipt of the shipment, proceed as follows: – Immediately record the transport damage found 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 sales department at Maschinenfabrik Reinhausen GmbH and the relevant insurance company.

  • Page 21: Storage Of Shipments

    4.5 Storage of shipments When selecting and setting up the storage location, ensure the following: – Store the product and accessories in the original packaging until installa- tion. – Protect stored goods against moisture (rain, flooding, water from melting snow and ice), dirt, pests such as rats, mice, termites etc. and against unauthorized access.

  • Page 23: Wiring Requirement Of Operating Site

    5.1.2 Wiring requirement of operating site Note the following when wiring the operating site: – Do not route lines which cause interference (e.g. supply lines) and lines susceptible to interference (e.g. signal lines) in the same cable duct. – Maintain a distance of more than 100 mm (3.94") between lines which cause interference and those which are susceptible to interference.

  • Page 24: Cable Recommendation

    5.2 Cable recommendation Please note the following recommendations from Maschinenfabrik Rein- hausen GmbH when wiring the device: – Excessive line capacitance can prevent the relay contacts from interrupting the contact current. In control circuits operated with alternating current, take into account the effect of the line capacitance of long control cables on the function of the relay contacts.
  • Page 25 Use a suitable thermometer pocket in accordance with IEC 60076-22-7 (corresponds to DIN EN 50216-4). 1. Fill 2/3 of the thermometer pocket with oil. 2. Unscrew the double screw connection G1 and screw into the thermometer pocket. Figure 4: Double screw connection G1 and thermometer pocket 8122419/01 EN .
  • Page 26 NOTICE!  Damage to the device! Ensure that the counter nut is free be- fore aligning or turning the combi well. Insert the combi well into the ther- mometer pocket, align it and screw tight with the counter nut. Figure 5: Inserting the combi well into the thermometer pocket Mounting .
