Honeywell HVFD Smart Drive Tips and Notes READ MANUAL FIRST 1 Drive SELECTION tips Obtain motor nameplate information 1 Drives are sized by voltage and current not HP Verify the current capacity of the selected drive meets or exceeds the motor name plate It is acceptable to use a drive with higher amp amp HP rating than the motor name plate if needed If using single phase input in lieu of 3 phase power feed de rate the drive selection per recommendations Radio Frequency Interference RFI and drive chokes are required in most commercial applications When not provided as standard equipment purchase as an extra cost option HIGHLY recommended If existing cables are used and the drive to load distance exceeds 100 add an external dV dT output filter Verify physical space requirements Allow for minimum clearances for ventilation and service Select NEMA 1 chassis for most commercial applications Open chassis models should be installed in separate ventilated cabinets Select a NEMA 12 drive chassis when installed in harsh environments Select NEMA 3R enclosure for outside applications Verify ambient operating temperatures do not exceed drive specifications Allow for extended lead time Some drives and drive bypass combinations have extended delivery times 2 Drive INSTALLATION READ the installation instructions before proceeding 9 7 2 3 4 5 6 Verify drive matches the order Store and protect d
