Koma kupatula nkhani ya zachuma, pali nkhani yachitetezo yomwe ndimaiona kuti ndi yosangalatsa kwambiri. Magalimoto a sitima amagwira ntchito m'malo omwe kulephera kwa magetsi kungakhale ndi zotsatirapo zoopsa - osati pazida zokha, komanso kwa okwera ndi ogwira ntchito. Njira yolephera pang'onopang'ono monga kupumula kwa screw terminal, komwe kumapereka zizindikiro zochenjeza zomwe zitha kuzindikirika poyang'aniridwa nthawi zonse, imatha kuthetsedwa m'gulu lankhondo lomwe limasamalidwa bwino. Koma nthawi zowunikira zikasowa, kapena njira yowunikira ikapanda kuphatikiza kujambula kutentha kwa kulumikizana kwamphamvu, zizindikiro zochenjeza zimasowa mpaka kulephera kuchitika. Popeza malo olumikizirana masika a masika amalephera kuzindikira komanso nthawi yomweyo pazifukwa zomwe zingapangitse kuti malo olumikizirana masika alephere pang'onopang'ono komanso mosayembekezereka, njira yolumikizirana masika ndi yotetezeka kwambiri pakugwiritsa ntchito njanji..

Ma block a sitima a J-Guang a PCT-211 a DIN a masika agwiritsidwa ntchito m'mapulogalamu opitilira 30 a magalimoto a sitima padziko lonse lapansi, ndipo ntchito yathu yogwirira ntchito yopitilira maola 8 miliyoni ikugwira ntchito. Deta yathu yoyesera ya EN 50155, yomwe imapezeka kwa mainjiniya onse ogula zinthu akapemphedwa, ikuwonetsa kukhazikika kosalekeza kwa kukana kulumikizana m'ma axes onse atatu oyesera pa magawo a kugwedezeka kwa Gulu 1. Ngati mukufotokoza ma block a terminal a projekiti yatsopano ya sitima kapena kuwunika kukweza ku gulu lomwe lilipo, ndikulandila mwayi wokambirana zomwe mukufuna.
