Zizindikiro zolowetsa zimagawana chizindikiro chimodzi chobwerezabwereza. Kuti mukhale ndi chitetezo chokwanira cha phokoso, yambitsani ma siginecha ogwirizana, malo owonetsera magetsi, ndi malo omwe ali pafupi ndi malo amodzi. Chizindikiro chofala (monga chimatanthauziridwa ndi Miyezo yambiri) ya gawo lolowera ndi mbali yoyipa ya 24 volt supply. Malo a chassis a module amapita ku I/O Terminal Block ground terminal. Kuti muteteze chitetezo chaphokoso, gwirizanitsani izi ndi chassis yotsekera ndi waya wamtali wautali. Ma transmitters awiri oyendera ma waya (mtundu wa 2) amayenera kukhala ndi zolowera pawokha kapena zopanda maziko. Zida zoyendera magetsi ziyenera kugwiritsa ntchito mphamvu yofanana ndi gawo lolowera. Ngati chopereka chosiyana chiyenera kugwiritsidwa ntchito, gwirizanitsani chizindikiro chofala ndi module wamba. Komanso, tsitsani mfundo imodzi yokha pa siginecha yodziwika bwino, makamaka pagawo lolowera. Ngati magetsi sanakhazikike, maukonde onse a analogi ali pamtunda woyandama (kupatula zishango za chingwe). Motero derali likhoza kukhala lapadera ngati liri ndi gawo lina lakutali. Ngati mawaya otetezedwa agwiritsidwa ntchito kuchepetsa phokoso la phokoso, mawaya a chishango amayenera kukhala ndi njira ina yopita pansi ndi malo aliwonse opangira magetsi kuti asapangitse phokoso chifukwa cha kukhetsa kwamagetsi. Mawaya atatu otumiza amafunikira waya wachitatu kuti apereke mphamvu. Chishango chikhoza kugwiritsidwa ntchito ngati kubwerera kwa magetsi. Ngati dongosololi liri lokha, waya wachitatu (chingwe cha katatu) chiyenera kugwiritsidwa ntchito m'malo mwa chishango cha mphamvu, ndipo zishango zimayikidwa pansi. Payokha, magetsi akutali angagwiritsidwenso ntchito. Malo oyandama amayenera kugwiritsidwa ntchito kuti apeze zotsatira zabwino. Kuyika zinthu zonse ziwiri kumapanga chizungulire. Dera litha kugwirabe ntchito ngakhale izi, komabe kupeza zotsatira zabwino kumafunikira kutsata kwamphamvu kwamagetsi kwa transmitter. Ma Isolated 4 ma transmitters amatha kupewa zovuta za loop pansi ndi masensa omwe ali kutali. Ngati gawoli layikidwa pa I/O Terminal Block yokhala ndi Box Terminals kapena I/O Terminal Block yokhala ndi Zotchinga Zotchinga, Mbali Yothandizira Yothandizira iyenera kugwiritsidwa ntchito popereka ma waya owonjezera. Kwa I/O Terminal Block yokhala ndi Wire to Board Connectors, malo olumikizirana akunja nthawi zambiri amakondedwa, ngakhale block Terminal Yothandizira ingagwiritsidwe ntchito. Mabotolo Othandizira Othandizira ali ndi ma terminals onse olumikizidwa mkati. The Auxiliary Terminal Block yokhala ndi ma terminals okhala ndi ma terminals 13, iliyonse yomwe imakhala ndi AWG # 14 imodzi (avg 2.1mm2 cross section) mpaka AWG #22 (avg 0.36mm2 cross section) waya, kapena mawaya awiri mpaka AWG #18 (avg. 0.86mm2 cross section). Mbali Yothandizira Terminal Block yokhala ndi zotchinga ili ndi ma terminals asanu ndi anayi, iliyonse yomwe imatha kukhala ndi waya umodzi kapena awiri mpaka AWG #14 (avg 2.1mm2 cross section). Pa ma transmitters a mawaya 3 ndi 4, I/O Terminal Block yokhala ndi materminal box ndi Auxiliary I/O Terminal Block ingagwiritsidwe ntchito popanda mizere ina yowonjezera. Mzere wowonjezera wama terminal ndiwofunikira pa I/O Terminal Block yokhala ndi zotchingira zotchingira ndi Mbali Yothandizira. Ma terminals a +24V Out ndi omwe amapangidwa wamba kuchokera ku DC+ kuyendetsa masensa a waya a loop-powered 2. Pa china chilichonse kupatula ma transmitters a 2-waya, jumper the Auxiliary Terminal Block to DC-.
