Installation txoj kev ntawm ob-hauv-ib xob laim ntes:
1. lub koob yees duab network ob-hauv-ib lub teeb ntes tau teeb tsa nyob rau hauv series nyob rau hauv pem hauv ntej ntawm lub network koob yees duab chaw nres nkoj (lub "INPUT" qhia lub davhlau ya nyob twg yog txuas nrog rau kab, thiab lub "OUTPUT" qhia lub davhlau ya nyob twg txuas nrog lub koob yees duab tiv thaiv) , thiab tom qab ntawd PE grounding davhlau ya nyob twg yog welded los yog bolted rau hauv av daim phiaj nrog tooj liab tub ntxhais hlau.
2. Txoj kev sib txuas ntawm lub hwj chim kab davhlau ya nyob twg ntawm lub koob yees duab network ob-hauv-ib lub teeb ntes hluav taws xob: ob qhov kawg ntawm lub zog hluav taws xob txuas nrog "L / +" thiab "N / -" raws li.
3. Kev sib txuas ntawm RJ45 network teeb liab kab ntawm lub koob yees duab network ob-hauv-ib xob laim ntes: nws tau nruab rau hauv series, thiab RJ45 siv lead ua taub hau yog txuas ncaj qha rau hauv.
4. Qhov chaw hla ntawm kev tiv thaiv xob laim hauv av yuav tsum yog ≥2.5mm2 thiab luv luv li sai tau. Kev txhim kho ntawm cov khoom tiv thaiv xob laim no yuav tsum muaj qhov kev tiv thaiv hauv av tsawg dua 4Ω, thiab kev tiv thaiv kev tiv thaiv xob laim yog qhov zoo tshaj plaws thaum cov xaim hauv av thiab cov av tiv thaiv tau tsim nyog.
5. Lub teeb ntes hluav taws xob no tsis muaj kev saib xyuas, thiab kev ua haujlwm ntawm lub teeb ntes hluav taws xob yuav tsum tau kuaj xyuas thiab kaw lub sijhawm tom qab cua daj cua dub.
1. Ua ntej lub surge protector hlua txuas nrog cov cuab yeej tiv thaiv, lub hwj chim yuav tsum raug muab tua, thiab kev ua neej nyob yog txwv nruj heev. .
2. Tso rau hauv cov kab ntawm cov kab ntawm cov khoom tiv thaiv, kev sib txuas ntawm kev sib txuas yuav tsum txhim khu kev qha, thiab cov khoom tiv thaiv surge muaj cov khoom nkag (IN) thiab cov zis (OUT) cov cim. Cov zis davhlau ya nyob twg txuas nrog cov khoom tiv thaiv, tsis txhob txuas rov qab. Txwv tsis pub, lub surge protector yuav puas thaum xob laim tawm tsam, thiab cov khoom siv yuav tsis muaj kev tiv thaiv zoo (saib rau hauv daim duab qhia kev teeb tsa thiab xov hluav taws xob).
3. Cov xaim hauv av (PE) yuav tsum muaj kev ntseeg siab rau hauv av xaim ntawm kev tiv thaiv surge, thiab qhov ntev yuav tsum yog qhov luv tshaj plaws kom ua tiav qhov kev tiv thaiv zoo tshaj plaws.
4. Cov khoom siv yuav tsum tau muab tshem tawm thaum txhim kho cov xaim hauv av kom tsis txhob muaj kev puas tsuaj rau cov khoom siv vim qhov kev taw qhia ntawm cov hluav taws xob muaj zog xws li hluav taws xob vuam los ntawm cov xaim hauv av kawg.
5. Txuas cov xaim hauv av ntawm lub surge protector thiab lub plhaub hlau ntawm cov khoom siv rau hauv av collector bar.
6. Thaum lub sij hawm siv, lub surge protector yuav tsum tau kuaj tsis tu ncua. Yog tias nws ua tsis tau, nws yuav tsum tau kho lossis hloov lub sijhawm kom muaj kev nyab xeeb ntawm cov cuab yeej tiv thaiv.
7. Cov uas tsis yog kws tshaj lij yuav tsum tsis txhob cuam tshuam nws.
