Soft starter ventilation<br />
On soft starters installed with a cooling fan, the fan is factory set to switch on automatically as soon as the heatsink temperature reaches<br />
46°C (114.8°F).<br />
It is switched off when the heatsink temperature falls back to 43°C (109.4°F). This behavior can be mo dified by adjusting the FAn parameter<br />
in IO menu on page 61.<br />

Mounting in a General Purpose Metal Enclosure<br />
Observe the mounting recommendations on the previous page.<br />
To help proper air circulation in the soft starter:<br />
• Install ventilation grilles.<br />
• Verify that ventilation is adequate: if not install a forced ventilation unit, with a<br />
filter if necessary.<br />
Derate the soft starter current IcL by 2.2% per °C for temperatures above 40°C up to<br />
60°C (104°F up to 140°F).<br />
