It is good practice to always fit the protective cap when a connector is unmated topside prior to deployment to provide mechanical protection. -
Page 18: Preparing Product For Use Or Storage
Document No: IOM-006 Issue Date: 16/11/2020 Revision: Page: 18 of 35 PREPARING PRODUCT FOR USE OR STORAGE Product protection and packaging The REDU is designed to withstand vibration that occurs during transportation. The REDU is manufactured primarily from 316L stainless steel (UNS S31603), and as such is designed to withstand harsh environments. -
Page 19: Unpacking
Document No: IOM-006 Issue Date: 16/11/2020 Revision: Page: 19 of 35 Unpacking Remove wrapping material taking care to inspect for any surface damage or items that may have become separated from the product. For parts supplied individually and wrapped in materials, do not use a knife to cut the wrapping material, as this may cause damage to any elastomeric parts or painting of the product. - Page 20 Repackaging to prevent damage in transport In the event of a requirement to return the REDU back to Siemens Energy, the REDU should be transported back in its designated transportation Box. Transport or topside protective cap should be fitted to the connector(s) and care should be taken to protect the connector(s) with bubble wrap or similar wrapping materials to avoid any surface damage.
