During primary power interruptions, the unit routes energy from the specified external battery cell to maintain memory retention across CPU cards. High-density contact pins ensure low-resistance connectivity without introducing noise onto deterministic backplane bus communication lines or altering firmware flash compatibility during transient voltage drops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the DSSB 140 unit ship with the internal backup battery included?\u003c\/p\u003e\n\u003cp\u003eA: No, the DSSB 140 is a carrier unit that requires one separate battery cell part number 4943013-2 for complete operation.\u003c\/p\u003e\n\u003cp\u003eQ: Can the DSSB 140 battery carrier be replaced or serviced while the main controller is online?\u003c\/p\u003e\n\u003cp\u003eA: Hot-swapping limits depend on system power redundancy; main rack power must remain stable to ensure RAM memory contents are preserved while the battery unit is disconnected.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eVerify that the primary rack power supply is active before installing or replacing the backup battery module to prevent memory loss.\u003c\/li\u003e\n\u003cli\u003eInsert the required battery cell (part number 4943013-2) into the DSSB 140 housing with correct polarity orientation.\u003c\/li\u003e\n\u003cli\u003eSlide the DSSB 140 housing into the designated subrack guide slot until backplane power connectors fully engage.\u003c\/li\u003e\n\u003cli\u003eTighten front panel retention screws to secure physical mounting stability and complete chassis grounding connection.\u003c\/li\u003e\n\u003cli\u003eVerify cabinet ambient temperature remains within 0 to 55 deg C to maximize backup cell operational life.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":53221837930805,"sku":"DSSB 140 48980001-P","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/DSSB14048980001-P1.png?v=1785221939","url":"https:\/\/www.5gplc.com\/products\/dssb-140-48980001-p-abb-control-system-accessories","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
