    Unpacking, inspecting and storing 1MRS757641 G Unpacking, inspecting and storing Removing transport packaging Protection relays require careful handling. Examine the delivered products to ensure that they have not been damaged during the transport. Remove the transport packaging carefully without force. Attach the protective film (supplied with the protection relay) on the top side of the unit for the installation phase.

  • Page 17: Inspecting Product And Delivery Items

    Returning a product damaged in transit If damage has occurred during transport, appropriate actions must be taken against the latest carrier. Please inform the nearest ABB office or representative. Notify ABB immediately if there are any discrepancies in relation to the delivery documents. Storing If the protection relay is stored before installation, it must be done in the original transport packaging in a dry and dust free place.
