If necessary the appropriate technical resources (lifting cart orcrane for large weights) and tools must be used. Improper handling or use ofthe wrong tools may cause damage to the soft starter.The Soft starter DS7 is only designed for use as built-in device.Take sufficient counter measures in the case of:• Contaminated cooling air, such as dust, fluff, grease:This can cause short-circuits on the cards(counter measures: installation of filters, separate ventilation circuit).• Aggressive gases:These can corrode circuit-board conductors(counter measures: flush mounting of filters, separate ventilation circuit).• Contaminated filters:These can cause overheating (counter measure: regular cleaning).To prevent overheating, observe the following points:• Ensure the free flow of the cooling air both to and from the device.• No devices that produce considerable amounts of heat in the proximity ofthe soft starter.• Observe the mounting clearance above and below the soft starter as thetemperature of the cooling air will otherwise reach impermissible valuesand the soft starter will switch off.Figure 39: Cooling air supply> ϑϑ = -5... +40 °C(ϑ = 23... +104 °F)
