1. Output voltage will not exceed Input voltage, with the exception of 120 V models. All controllers produce 3 Φ output power, regardless of input phase.
2. The distance of the fan from the ceiling should be measured from the top of the winglets to the ceiling.
CAUTION: Big Ass Fans requires that the Powerfoil X2.0 fan be supplied from one of the following types of transformers:
575–600 V models: 575/330 V Wye secondary (neutral not utilized)
400–480 V models: 480/277 V Wye secondary (neutral not utilized)
200–250 V models: 208/120 V Wye secondary (neutral not utilized)
240/120 V Delta secondary (Wild/High Phase B)
Integration into any other power distribution scheme may result in improper fan operation or premature hardware failure! See
