Starting the System
Section 7
(continued)
Consult motor manual to determine the wire size for the application. Ensure the ground connection to the motor
is continuous. Connect wires to the output terminal block labeled T1/U, T2/V, T3/W, and GND/ . Connect the
ground wire to the terminal labeled GND/ . Connect the other phase leads to T1/U, T2/V and T3/W.
For CentriPro Motors, connecting T1/U to Red, T2/V to Black and T3/W to Yellow will give the correct rotation.
Danger
The controller has high leakage current to ground. The output terminals marked

voltage
of the controller. Use metal conduit and metal conduit connectors. Size the conduits according to the
NEC, CEC or local codes. Use the wire sizing chart in the appendix to determine the size of the input power wires.
Connect the conduit and insert the wires into the far left opening on the controller. Connect wires to the "INPUT"
terminal block. Connect the ground wire to the terminal labeled GND. For three phase input, connect the input
phase wires to L1, L2 and L3. For single phase input, connect the input wires to L1 and L3. If single phase input is
used the motor overload switches must be set to 50% or lower.
Caution
The wire used for input power connections on models SPD20300 and SPD20300F must have a
temperature rating of 90ºC minimum.

Note
If single phase input power is used the Motor Overload switches must be set to 50% or lower or
nuisance input phase loss errors can result.
