Minimum power cycling time
The variable speed drive is equipped with an inrush circuit, limiting the starting (inrush) current when the system is
powered up.
CAUTION
Frequent cycling of power to the drive can damage the drive! Wait at least 5 minutes between cycles (connecting and
disconnecting power to the drive).
The OEM must place an equivalent notice on the unit!
Internal cooling fan
High performance variable speed cooling fan, supply voltage 16 V. Nominal operating point 74 CFM (126 m3/h) @ 89Pa
static pressure.
