    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 and knocks.

  • Page 24: Transportation, Receipt And Handling Of Shipments

    4.4 Transportation, receipt and handling of shipments In addition to vibrations, jolts must also be expected during transportation. In order to prevent possible damage, avoid dropping, tipping, knocking over and colliding with the product. If the packaging tips over or falls, damage is to be expected regardless of the weight.

  • Page 25: Storage Of Shipments

    Hidden damage When damage is 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. –...

  • Page 26: Mounting

    5 Mounting This chapter describes how to correctly mount and connect the device. The pressure relief device is mounted on a device flange on the transformer or on-load tap-changer. Note the connection diagrams provided. DANGER Electric shock! Risk of fatal injury due to electrical voltage. Always observe the following safety regulations when working in or on electrical equipment.
  • Page 27 CAUTION Risk of injury and damage to property! Escaping hot oil and gas can lead to injuries and damage to the device. Direct escaping hot oil and gas away from people and critical transformer parts. The pressure relief device can be mounted horizontally or vertically, as close as possible to potential error sources.

  • Page 28: Checking The Pipe Flanges

    5.1 Checking the pipe flanges The pipe flanges must be flush and clean to allow the device to be positioned with the least possible stress. NOTICE!  A residual distance between the flanges caused by a deviation in evenness can cause damage to the flanges.Even slight unevenness can cause the flange of the device to be curved too much, leading to cracks in the flange caused by the resulting transverse stress.
