3. Normal Running And Installation Conditions

3.1 Ambient air temperature: -5℃~ +40℃, the average value should not exceed +35℃ within 24 hours3.2 Elevation: at most 2000m.
3.3 Atmospheric conditions: When the temperature at 40, the relative humidity of atomsphere should beat the most 50%. When at relatively low temperatures, it could have higher relative humidity. Monthlymaximum relative humidity could be not more than 90%. Special measures should be taken due tooccurrence of dews.
3.4 Class of pollution: Class 3
3.5 Installation category: Ⅲ
3.6 lnstallation conditions: Degree of inclination between fiting surface and vertical surface should notexceed
3.7 lmpact shock: Product should be installed and used in the place where often shakes and impacts

4.Type Of Construction

Magnetic starter has a case with protection category lP65, jRS4 thermal overload relay connect with terminals through three wires, and fix together with CX2 contactor. There are two buttons on the case, green one is “tumn on”,red one is “turn off” or “reset”
