DAD fans are equipped with a PTC thermis-
tor in the motor winding as standard.
For protection, connect a PTC thermistor trigger-
ing system. The triggering system must perman-
ently disconnect the fan from the power supply if
temperatures get too hot. For PTC thermistor trig-
gering systems from the Maico range of ac-
cessories → www.maico-ventilatoren.com.
