LE LOEB <br /> ELECTRIC <br /> 1.0 Program Overview <br /> This scope of work is designed for teams that are completing both the Arc Flash Relay Install (AFRI) <br /> Program and the Parts, Repair, and Maintenance (PRM) tasks. This work consists of several major <br /> services, most of which must be executed during a single 12-14-hour utility outage. <br /> • Arc Flash Relay Installation <br /> o Through light sensors and current monitoring, arc flash relays will rapidly detect and clear <br /> most arc flash events before these events cause significant damage to equipment. <br /> • Arc Flash Study <br /> o Arc Flash Label Application <br /> ■ Updated Arc Flash Label to be installed considering the relay clearing time. <br /> ■ Arc Flash refresh will not be part of this SOW. <br /> ■ Reference Appendix P for label template and further guidance. <br /> • BMS Integration <br /> o By tying in the Arc Flash Relay to the site's BMS, Amazon will have the ability to monitor <br /> the health of its main switchboards. <br /> • GSF Critical Load Support <br /> o Additional temporary power plans required at GSF PM due to refrigeration units. <br /> • Infrared (IR)Window Installation <br /> o By installing IR Windows on the line side of the main switchboards and upstream <br /> Amazon or landlord owned equipment, infrared scans can safely be performed on <br /> equipment that has an incident energy level that is greater than 40 calories. <br /> • Infrared window installation in opportune situations is acceptable downstream <br /> of the main. <br /> • Infrared (IR) Scanning <br /> o IR scan is only required when thermal deficiency was corrected. The scan is the <br /> responsibility of the primary contractor and must be completed the following day <br /> when site is normally loaded. <br /> • Preventative Maintenance (PM) <br /> o Formally known as"LVPM" <br /> o Major Service and Preventive maintenance based on ANSI/NETA MTS standard and Amazon PM <br /> Requirement Appendix A. <br /> o Correction of known issues from previous IR scans which will be provided prior to site walks. <br /> • UPS Replacement <br /> o Upgrading original AFRI install sites that didn't have UPS backup or UPS that doesn't meet current <br /> design standards. These older UPS are at the end of their battery life. <br /> The purpose of this program is to ensure electrical distribution equipment is maintained and in good <br /> working order to prevent unplanned interruptions to the facilities operations. In addition, arc flash relays <br /> are to be installed to lower the safety risk to Amazon associates or contractors operating or repairing <br /> electrical distribution equipment. <br /> 31 Page <br />
