Instructions for wiring an electric motor

Choose the correct motor:
1. Phase (Single or Three phase)
2. Cycle (60hz or 50hz)
3. Horsepower (.75 – 1.0 – 2.0 – 5.0)
4. RPM (revolutions perminute)
5. Operator type and speed (important because the motor / gearpump per operator should match)

When it comes to wiring an electric motor you should know that the leads that come out of theelectric motor are called “T” leads (i.e.; T1, T2, T3----T8). These leads come from the motor windings and protrude into the motor’s J box. The “J” box is where the wiring connections are made, inside theJ box you can actually see the “T” leads come out of the motor body. To avoid confusion line leads (incoming power to the operator) look like this – L1, L2, and L3.

Single Phase Motor

NameplateData Look:
VOLTS 115/208-230

* Choose the correct wiring voltage either “High” or “Low”

Six “T” lead motor -- Choose the correct wiring voltage either “High” or “Low”
|Low - 115v|Connect L1 to T1, T3 and T8 |
| |Connect L2 to T4, T5 and T2 |
|High – 208-230v|Connect L1 to T1 |
| |Connect L2 to T4 and T5 |
| |Connect T3, T8and T2 together. |

Four “T” lead motor (current model) -- Choose the correct wiring voltage either “High” or “Low”
|Low - 115v |Connect L1 to T1 and T3|
| |Connect L2 to T2 and T4 |
|High – 208-230v |Connect L1 to T1|
| |Connect L2 to T4 |
| |Connect T3 and T2 together. |
