Powtech frequency drive Installation introduction

vector inverter should be installed at a indoor place with good ventilation and used the wall-mounted method; moreover, there must be enough room between it and its surrounding article or baffle (wall). It is shown as the following chart.

 

Application site:

According to user's loading,the PT300 series inverter have three load type to choose: light load(P rated),heavy load(G rated),and heavy load(H rated).

The difference between the three rated loads:

application fields: metallurgy, petroleum, chemical, textile, electric power, building materials, coal, medicine, food, paper, plastics, printing and dyeing, lifting, cable, washing, water supply, heating and ventilation, sewage treatment and other industries, machinery and equipment for: Drawing machines, blenders, cutting machine, winding machinery, compressors, air pumps, grinders, conveyors, hoist, centrifuges and various speed control machinery.
