4, Mounting Mamiriro
1) Ambient tembiricha yemhepo
1) Tichifunga tembiricha yakawandisa yekumhanyisa kuchembera kwezvikamu zvepurasitiki, muganho wepamusoro haupfuuri +40 ℃.
Tichifunga kuti yakanyanyisa yakaderera ambient tembiricha zvakanyanyisa
inoshandura kukwana kwenhengo yezvimiro, muganho wepasi hauwanzo kuderera pane -5 ℃.
Tichifunga nezvehupenyu hwebasa remuchairi wedunhu, avhareji kukosha kwemaawa makumi maviri nemana haisi kupfuura +35 ℃.

Cherechedza:

① Mamiriro ekushanda eiyo yakaderera muganho kukosha ndeye -10 ℃ kana -25 ℃.Mushandisi anofanirwa kuzivisa kukambani kana achiodha.
②Mamiriro ekushanda emuganho wepamusoro unopfuura +40 ℃ kana iyo yakaderera muganho kukosha yakaderera pane -25 ℃, mushandisi anofanira kutaurirana nekambani.
2)Kuisa nzvimbo
Kukwirira hakupfuuri 2000m;
Dziviriro yedunhu zvinodiwa;
Iyo yekuisa poindi inoverengera pfupi redunhu ikozvino Ik haisi kupfuura 3000A;
Mutambo wedunhu uchaiswa maererano nezvinodiwa zvekushandiswa kwebhuku, vertical inclination yedunhu rinoputika haifaniri kudarika 5 °, Kudengenyeka kwezvakatipoteredza hakusi kupfuura 5g.
3) Atmospheric Conditions
Hunyoro hwemuchadenga haupfuuri 50% pane ambient air tembiricha +40 ° C. Inogona kuva nehunyoro hwepamusoro pane tembiricha yakaderera.Mwedzi wepakati wepakati hunyoro hunyoro hwemwedzi wakanyorova ndeye 90%, uye avhareji tembiricha yemwedzi ndeye +25 ° C uye funga nezve condensation pamusoro pechigadzirwa nekuda kwekushanduka kwekushisa.
4) Kusvibiswa kwemazinga
Chiyero chekusvibisa chinhanho chechitatu.
5) Installation Category
Iyo yedunhu inotyora yekudzivirira yedunhu yakaiswa muchikamu III.
6) Chikamu chemuchinjiro wewaya chinogadziriswa zvinoenderana neyakajairwa yakajairwa kupisa ikozvino Ith yedunhu breaker.
