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

DANGER

Hazardous voltage

The controller has high leakage current to ground. The output terminals marked “GND” or “ ” must be directly connected to the motor ground. Failure to properly ground the controller or motor will create an electrical shock hazard.

Input Power Connections

DANGER Make sure disconnect switches or circuit breakers are securely in the OFF position before making this connection. Run the input power wires from the fused disconnect through metal conduit to the bottom 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.

Danger

DANGER

Hazardous voltage

The controller has a high leakage current to ground. The input terminals marked “GND” must be directly connected to the service entrance ground. Failure to properly ground the controller or motor will create an electrical shock hazard.

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.

Note

Do not use GFCI protection with this controller. Nuisance tripping will result.

Danger

DANGER

Hazardous voltage

Status Code Indicator Light is not a voltage indicator! Always turn off disconnect switch and circuit breaker and wait 5 minutes before servicing.

Danger

DANGER

Hazardous voltage

The controller will remain electrically charged for 5 minutes after power is turned off. Wait 5 minutes after disconnecting power before opening controller access cover as there is a severe shock hazard.
