(1) For frame B and C drives only, a jumper is required between terminals SA and SB for 115V AC control input power. See PowerFlex DC Control Circuit Power Connections on page 87 for more information.
(2) An Isolation Transformer and/or 3…5% impedance Line Reactor is required. If the Isolation Transformer provides the required 3…5% impedance, a Line Reactor is not required. See Appendix A in the PowerFlex Digital DC Drive User Manual, publication 20P-
UM001, for recommendations.
(3) AC input fuses for the armature converter are customer supplied for frame A and B drives and are internally mounted on frame C and D drives. See PowerFlex DC Drives Circuit Protection on page 139
for fuse recommendations.
(4) Par 140 [Digital In8 Sel] set to 31 “Contactor”
(5) If using the +24V internal power supply, terminal 18 (24V common) must be jumpered to terminal 35 (digital input common).
(6) Customer supplied armature output fuses are required on four quadrant and are recommended on two quadrant Frame A and B drives. See PowerFlex DC Drives Circuit Protection on page 139
for fuse recommendations.
(7) Par 1391 [ContactorControl] = 3 “DC Cntctr” and Par 1392 [Relay Out 1 Sel] = 25 “Contactor”. Important: Terminal 35 and 36 are on the Control Power / Relay Terminal block, NOT the I/O terminal blocks. See PowerFlex DC I/O Signal and Control Wiring on
page 118 for locations.
(8) Frame C & D drives only require an external power supply for the heatsink cooling fan. See PowerFlex DC Frame C Heatsink Cooling Fans Power Supply Terminals on page 91
and PowerFlex DC Frame D Heatsink Cooling Fans Power Supply Terminals on page 92 for
more information.
(9) See PowerFlex DC Field Converter Connections on page 84
