The SSW07 Quick Start Guide is a supplement to help get the SSW07 started quickly using the most common installation
and configuration options. This SSW07 Quick Start Guide is not meant to replace the SSW07 User’s Manual. For detailed
instructions, safety precautions, proper mounting, installation, configuration, and operation please refer to the SSW07
User’s Guide. Warning: Only qualified personnel should plan or implement the installation, start-up, operation and
maintenance of this equipment. Personnel must read the entire SSW07 User’s Guide before attempting to install, operate
or troubleshoot the SSW07.

Basic Wiring:

1. Mount the SSW07 to a flat vertical surface.

2. Connect the three-phase incoming power leads to the R, S, and T connections on the power terminal (refer to
Figure 1). Connect the motor leads to the U, V, and W connections on the power terminal and connect the
GROUND lead to PE on the chassis (refer to Figure 1). Note: Only three-phase AC motors can be used.

3. Connect the control power line (L) and neutral (N) leads to the A1 and A2 connectors (refer to Figure 1).

Start-up by Voltage Ramp:

1. The soft starter should be powered up with a display of “RDY”.

2. Press the key to enter the programming mode.

3. Press the or key to select P000.

4. Press the key to change value of parameter.

5. Press the or key to set to “5” to allow access to parameters.

6. Press the key to save the selected option.

7. Press the or key to select P219.

8. Press the key to change value of parameter.

9. Press the or key to set to “0” for keypad programming.

10. Press the to save the selected option.

(most common configuration)

11. Press the or key to select P202.

12. Press the key to change value of parameter.

13. Press the or key to set to “0” for Voltage Ramp.

14. Press the key to save the selected option and exit the programming mode.

15. Press the or key to select P003 (Motor Current).

16. Press the key to read the Motor Current value (This is a read parameter).

17. Press the key to operate soft-start via HMI.

18. Press the start key. The motor accelerates to full voltage and the bypass contact engages.

Note: If the direction of rotation is not correct, switch off the soft starter and swap any two wires at the motor

output.

19. Press the stop key. The motor decelerates until stopping by coast to rest. Time to stop depends on load

inertia and friction.

Note: For a complete description of Parameters and Error codes refer to Chapters 6 and 7 in the SSW07

Programming Manual.
