In–Delta Connections For Delta connected motors, the Soft–Start can be connected inside the delta windings.
This connection method is shown in Figure 2-2.

Notes:
1. See “Protective Devices” described previously in this section.
2. Use same gauge wire for Earth ground as is used for L1, L2 and L3.
3. Metal conduit should be used. Connect conduits so the use of a Reactor or RC
Device does not interrupt EMI/RFI shielding.
4. Derating factor for soft–start is 57%.
5. Parameter P6– Firing Mode must be set to 1.
6. X1 and X2 control terminal power must be present or the logic circuits will not work.
Either 115VAC or 230VAC can be used. Be sure the 115/230VAC switch (Control
Voltage Selector Switch) is set to the proper voltage before you apply power.
7. The X1 and X2 control voltage input has different VA ratings depending on enclosure
size, see Table 2-3.
8. For reversing operation, L1 and L2 should be switched. Reversing any two of the
three input phases will reverse the motor rotation.
9. To protect the control, be sure to add MOV protection. Refer to Appendix D for
additional information.

Fan Connections – Size 3 and 4 only Size 1 and 2 controls do not have fan connections. For Size 3 controls make
the fan connections as shown in Figure 2-3.The Fan and Control voltages must be the
same (both must be 115VAC or both must be 230VAC). 150VA (minimum) required.
