Phau ntawv yuav tsum tau suav hais tias yog ib feem tseem ceeb ntawm cov khoom no thiab yuav tsum tau nrog nws thaum nws hloov cov tswv cuab raws li ib tug siv rau kev txhim kho kom raug thiab siv raws li zoo raws li rau kev ruaj ntseg ceev faj.
RCF SpA yuav tsis muaj lub luag haujlwm rau kev teeb tsa tsis raug thiab / lossis siv cov khoom no.
CEEB TOOM: Txhawm rau tiv thaiv kev pheej hmoo ntawm hluav taws xob lossis hluav taws xob poob siab, tsis txhob tso cov khoom no los nag lossis av noo (tshwj tsis yog tias nws tau raug tsim tawm thiab ua rau siv sab nraum zoov).
SAFETY CEEB TOOM
1. Txhua qhov kev ceev faj, tshwj xeeb yog kev nyab xeeb, yuav tsum tau nyeem nrog kev saib xyuas tshwj xeeb, vim lawv muab cov ntaub ntawv tseem ceeb.
2.1 POWER SUPPLY NTAWM MAINS (kev sib txuas ncaj qha)
a) The mains voltage yog txaus txaus los koom nrog kev pheej hmoo ntawm electrocution; yog li ntawd, tsis txhob nruab lossis txuas cov khoom no nrog lub hwj huam hloov pauv.
b) Ua ntej fais fab tuag, xyuas kom meej tias tag nrho cov kev sib txuas tau ua kom raug thiab cov voltage ntawm koj lub ntsiab sib raug rau voltage qhia rau ntawm daim ntawv ntsuam xyuas ntawm chav tsev, yog tias tsis yog, thov hu rau koj tus neeg muag khoom RCF.
c) Cov khoom siv hlau ntawm lub tsev yog earthed los ntawm lub hwj chim cable. Yog hais tias qhov hluav taws xob tam sim no siv rau lub hwj chim tsis muab lub ntiaj teb kev sib txuas, hu rau tus kws tsim hluav taws xob tsim nyog rau lub ntiaj teb cov khoom no los ntawm kev siv lub davhlau ya nyob twg.
d) Tiv thaiv lub hwj chim cable los ntawm kev puas tsuaj; xyuas kom meej tias nws nyob rau hauv txoj kev uas nws tsis tuaj yeem txav los yog tsoo los ntawm cov khoom.
e) Txhawm rau tiv thaiv kev pheej hmoo ntawm hluav taws xob poob siab, tsis txhob qhib cov khoom: tsis muaj qhov seem hauv uas tus neeg siv yuav tsum nkag mus.
2.2 Hwj chim muab los ntawm txoj kev ntawm ib tug sab nrauv ADAPTER
a) Siv lub adapter tshwj xeeb nkaus xwb; xyuas lub mains voltage sib raug rau voltage qhia nyob rau ntawm lub adapter rating phaj thiab lub adapter tso zis voltage tus nqi thiab hom (direct / alternating) sib raug rau cov khoom nkag voltage, yog tias tsis yog, thov hu rau koj tus neeg muag khoom RCF; xyuas kom meej tias lub adapter tsis tau puas vim muaj kev sib tsoo / hits lossis overloads.
b) The mains voltage, uas lub adapter txuas nrog, yog qhov txaus txaus kom muaj kev pheej hmoo ntawm hluav taws xob: ua tib zoo saib thaum lub sijhawm sib txuas (xws li tsis txhob ua nws nrog ob txhais tes ntub dej) thiab tsis txhob qhib lub adapter.
c) Xyuas kom tseeb tias lub adapter cable tsis yog (lossis tsis tuaj yeem) nce los yog tsoo los ntawm lwm yam khoom (ua tib zoo saib xyuas cov cable nyob ze ntawm lub ntsaws thiab qhov taw tes uas nws tawm ntawm lub adapter).
3. Nco ntsoov tias tsis muaj cov khoom lossis cov kua dej nkag mus rau hauv cov khoom no, vim qhov no yuav ua rau muaj kev cuam tshuam luv luv.
4. Tsis txhob sim ua txhua yam haujlwm, hloov kho lossis kho uas tsis tau piav qhia hauv phau ntawv no.
Hu rau koj lub chaw pabcuam kev tso cai lossis cov neeg ua haujlwm tsim nyog yuav tsum muaj ib qho hauv qab no tshwm sim:
• cov khoom tsis ua haujlwm (lossis ua haujlwm tsis zoo);
• lub hwj chim cable tau puas lawm;
• Cov khoom lossis cov kua tau nkag mus rau hauv chav tsev;
• Cov khoom tau raug cuam tshuam hnyav.
5. Yog tias cov khoom no tsis siv rau lub sijhawm ntev, hloov nws thiab txiav lub hwj chim cable.
6. Yog tias cov khoom no pib tawm cov ntxhiab tsw txawv txawv lossis haus luam yeeb, hloov nws tam sim ntawd thiab txiav lub hwj chim cable.
7. Tsis txhob txuas cov khoom no rau txhua yam khoom siv lossis cov khoom siv uas tsis tau pom dua.
Rau kev tshem tawm kev teeb tsa, tsuas yog siv cov ntsiab lus tshwj xeeb thiab tsis txhob sim dai cov khoom no los ntawm kev siv cov khoom uas tsis tsim nyog lossis tsis tshwj xeeb rau lub hom phiaj no.
Tsis tas li xyuas qhov tsim nyog ntawm qhov chaw txhawb nqa uas cov khoom yog anched (phab ntsa, qab nthab, qauv, thiab lwm yam), thiab cov khoom siv rau kev txuas (ntsia hlau anchors, screws, brackets tsis muab los ntawm RCF thiab lwm yam), uas yuav tsum tau lav lub kev ruaj ntseg ntawm qhov system / installation dhau sijhawm, kuj xav txog, rau example, cov neeg kho tshuab kev vibrations ib txwm tsim los ntawm transducers. Txhawm rau tiv thaiv qhov kev pheej hmoo ntawm cov cuab yeej poob, tsis txhob muab ntau lub zog ntawm cov khoom no tshwj tsis yog tias qhov ua tau no tau teev tseg hauv phau ntawv qhia.
8. RCF SpA xav kom cov khoom no tsuas yog ntsia los ntawm cov kws tshaj lij cov neeg tsim khoom tsim nyog (lossis cov tuam txhab tshwj xeeb) uas tuaj yeem ua kom muaj kev txhim kho kom raug thiab lees paub nws raws li cov cai hauv kev quab yuam.
Tag nrho cov suab kaw lus yuav tsum ua raws li cov qauv tam sim no thiab cov kev cai hais txog cov tshuab hluav taws xob.
9. Txhawb nqa thiab trolleys
Cov khoom siv yuav tsum tsuas yog siv rau ntawm cov tsheb thauj khoom lossis kev txhawb nqa, qhov tsim nyog, uas tau pom zoo los ntawm cov chaw tsim khoom. Cov khoom siv / kev txhawb nqa / trolley sib dhos yuav tsum tau txav nrog ceev faj heev. Kev nres tam sim ntawd, lub zog thawb ntau dhau thiab cov plag tsev tsis sib xws tuaj yeem ua rau lub rooj sib txoos tig.
10. Muaj ntau yam khoom siv hluav taws xob thiab hluav taws xob uas yuav tsum tau txiav txim siab thaum txhim kho lub suab nrov (ntxiv rau cov uas nruj me ntsis acoustic, xws li lub suab siab, lub kaum sab xis ntawm kev pab them nqi, zaus teb, thiab lwm yam).
11. Tsis hnov lus
Kev raug cov suab nrov tuaj yeem ua rau tsis hnov lus mus tas li. Cov qib acoustic siab uas ua rau tsis hnov lus txawv ntawm ib tus neeg mus rau lwm tus thiab nyob ntawm lub sijhawm ntawm qhov raug. Txhawm rau tiv thaiv kom muaj kev phom sij txaus ntshai rau qib siab ntawm acoustic siab, txhua tus neeg uas raug rau cov qib no yuav tsum siv cov cuab yeej tiv thaiv tsim nyog. Thaum siv cov khoom siv hluav taws xob uas muaj peev xwm tsim tau cov suab nrov, nws yog qhov yuav tsum tau hnav pob ntseg ntsaws los yog lub pob ntseg tiv thaiv.
Saib cov kev qhia tshwj xeeb hauv phau ntawv qhia txog lub suab siab tshaj plaws uas lub suab nrov muaj peev xwm ua tau.
TSEEM CEEB
Txhawm rau tiv thaiv qhov tshwm sim ntawm lub suab nrov ntawm cov cables uas nqa microphone teeb liab lossis kab teeb liab (example, 0 dB), tsuas yog siv cov tshuaj ntsuam xyuas thiab tsis txhob khiav lawv nyob ib puag ncig ntawm:
- cov khoom siv uas tsim cov khoom siv hluav taws xob siv hluav taws xob siab (example, siab zog transformers);
- mains cables;
- kab uas muab cov suab nrov.
Kev ua haujlwm ceev faj
- Tsis txhob thaiv qhov cua grilles ntawm chav tsev. Nyob cov khoom no kom deb ntawm tej qhov chaw tshav kub thiab ib txwm ua kom muaj cua txaus nyob ib ncig ntawm lub qhov cua grilles.
- Tsis txhob overload cov khoom no rau lub sijhawm ntev.
- Tsis txhob yuam cov khoom tswj (cov yuam sij, pob qhov rooj, thiab lwm yam).
- Tsis txhob siv cov kuab tshuaj, cawv, benzene lossis lwm yam khoom tsis haum rau kev ntxuav qhov chaw sab nraud ntawm cov khoom no.
RCF SpA xav ua tsaug rau koj tau yuav cov khoom no, uas tau tsim los lav kev ntseeg siab thiab kev ua haujlwm siab.
