I-WLD-1678C yokuvikela ugesi ongazimele iyisishintshi esibalulekile sezinhlelo zokuxhuma ugesi ovuselelekayo (njengamandla elanga, umoya, ukugcina amandla, njll.) ezinhlelweni zikagesi. Isetshenziswa ikakhulukazi ukuthola nokuhlukanisa "umphumela wokuzihlukanisa" - okungukuthi, lapho amanethiwekhi kagesi ephazamiseka ngenxa yokungasebenzi noma ukulungiswa, imithombo yamandla esabalalisiwe (njengama-inverter elanga) iyaqhubeka nokuhlinzeka ngogesi kumanethiwekhi endawo, okudala isimo esiyingozi sokusebenza ngokuzimele. Le divayisi iqinisekisa ukuphepha kwabasebenzi, ukuzinza kwemishini, kanye nekhwalithi yamandla kagesi ngokunqamula ngokushesha iphuzu lokuxhuma, futhi isetshenziswa kabanzi ezindaweni ezifana neziteshi zamandla elanga, amanethiwekhi amancane, kanye nokusabalalisa amandla ezimbonini.
