MountingSoft starter ventilationOn soft starters installed with a cooling fan, the fan is factory set to switch on automatically as soon as the heatsink temperature reaches46°C (114.8°F).It is switched off when the heatsink temperature falls back to 43°C (109.4°F). This behavior can be modified by adjusting the FAnparameter in IO menu on page 61.Fan flow ratesReferenceFrame Unit Standard With optional fan kitsize110 V 230 V 110 V 230 VATS22 D17, D32, D47 A m 3 /hour - - 28 31CFM (1) - - 16 18ATS22 D62, D75, D88 B m 3 /hour - - 28 31CFM (1) - - 16 18ATS22 C11, C14, C17 C m 3 /hour - - 108 108CFM (1) - - 64 64ATS22 C21, C25, C32, C41 D m 3 /hour 148 148 - -CFM (1) 87 87 - -ATS22 C48, C59 E m 3 /hour 148 148 - -CFM (1) 87 87 - -(1)Cubic Feet / MinuteMounting in a General Purpose Metal EnclosureObserve the mounting recommendations on the previous page.To help proper air circulation in the soft starter:• Install ventilation grilles.• Verify that ventilation is adequate: if not install a forced ventilation unit, with afilter if necessary.Derate the soft starter current IcL by 2.2% per °C for temperatures above 40°C upto 60°C (104°F up to 140°F).18 BBV51330 08/2012
