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.
Figure 1 - Power and Grounding Connections
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).

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.
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.

Local/Remote Modes (Optional HMI):
In the previous section the soft starter was operated from the keypad (Local Mode). Note the green local indicator LED on
the bottom right of the keypad. For the factory default programming, the selection of the operation mode (Local/Remote)
is made via the “Local/Remote” key (default is Remote). Pressing of the “Local/Remote” will alternate operation between
local & remote. Notice the indicator switches from the green to the red indicator LED when “Local/Remote” is pressed.
If you wish to use an external Local/Remote switch set P220=4, connect the switch to one of the Digital Inputs (DI1-DI3),
and set the corresponding parameter (P263 to 265=2).
To always run in Local mode set P220=0.
To always run in Remote mode set P220=1.
Control and Signal Connections:
Control and signal connections (digital inputs and relay outputs) are made through the terminals (see Figure 2).

2. Set P230 = 1 Digital Inputs
3. Set P263 = 1 DI1 Start (three wires)
4. Set P264 = 1 DI2 Stop (three wires)
Programming via dipswitches and trim pots:
To program DI2 for 3-wire control, refer to Figure 5 and perform the following:
1. Press and hold the reset button on the front of the SSW07 for 5 seconds to enter the programming mode.
Note: The reset button must remain pressed during programming.
2. When the programming mode is entered, two LED’s will illuminate (over-current and phase loss), indicating
that DI2 is programmed for fault reset.
3. To re-program for 3-wire control, switch the over-current dip-switch and return to the previous position. Three
LED’s will illuminate (over-current, phase loss, and phase sequence), indicating that DI2 is now programmed
for 3-wire control.
4. To change DI2 programming back to fault reset, switch the kick start dip-switch and return to the previous
position. Two LED’s will illuminate (over-current and phase loss), indicating that the DI2 is programmed for
fault reset.
5. Release the reset button to complete the programming.

Minimum Trim-Pots and Dip Switches to Set (P219 = 0):
Soft Starters are shipped with factory default values. If Trim-Pots and Dip Switches have been changed, it is advisable to
reset to factory default positions prior to a new installation by aligning all trim-pots and dip switches with the red factory
default dots. By default the control type is Voltage Ramp Starting. This control type is very easy to setup and is the most
commonly used starting method. Current Limit Starting is the second control type and is described below.
Motor Current Trim-Pot Setting - Factory default position is 100%
and is marked with a red dot. To protect the motor from overload,
obtain the full load amperage (FLA) off the motor and soft-starter
name plates. Using the following formula, calculate the percentage of
current that the motor will draw from the soft-starter and set the Motor
Current Trim-Pot accordingly.

of the soft-starter = 170A

N

N
of the switch = 140A / 170A = 0.823
– Motor Current Trim-Pot = 82.3%
Figure 6 – Motor Current Trim-Pot Location
Thermal Class Dip Switch Setting – Set to factory default of 30 if
not specified on the motor name plate. (Note: Factory default
positions are marked with red dots).
Note: These are the minimum settings for a perfect adaptation
between soft starter and motor. For a complete description of Trim-
Pot and Dip Switch settings refer to Chapter 4 in the SSW07 User’s
Guide.
Figure 7 – Thermal Class Dip Switch Location
Current Limiting for Loads with High or Constant Starting Torque:
Current limiting control is used to adapt the Soft Starter to the capacity limits of the power supply. It is often used with
power generators with limited output but may also be used to keep current draw to a minimum on loads with high or
constant starting torque.
Optional HMI:
1. Set P202 = 1 Type of control = Current Limit
2. Set P110 to % of current you wish to limit using example below.
3. Set P102 to desired acceleration.

Trim-Pot and Dip Switch Settings (Figure 8):
1. Set the Voltage Ramp/Current Limit dip switch to the Current Limit position.
2. Set the Current Limit Trim-Pot using the following example.

Figure 8 – Current Limiting
Notes: (1) The Current limitation must be set at a level that permits the motor to accelerate otherwise the motor will not
start. (2) If the full voltage is not reached at the end of the acceleration ramp time an E62 error will occur and the motor
will be disabled. For details on Fault Codes please refer to Chapter 6 in the SSW07 User’s Guide. (3) For details on
Current Limiting please refer to Chapter 5 in the SSW07 User’s Guide.

Soft Starter Operation:
The Soft Starter is now ready to operate via the 2-Wire or 3-Wire Control that was set up in the previous steps.
To start the motor, press the “Start Button” and the Soft Starter will accelerate up to speed (default acceleration time is
20sec). When full voltage is reached the internal bypass contactors will engage and switch the motor to the supply line.
To stop the motor, press the “Stop Button” and the Soft Starter will decelerate to the stop position (default deceleration
time is “Off” so the motor will coast to rest). For details on setting deceleration time and other trim-pots refer to Chapter 4
in the SSW07 User’s Guide.
Fault Codes:
Optional HMI:
When a fault is detected, the soft starter is disabled and the Fault Code is displayed (example E03). To restart the soft
starter after a fault has occurred, the soft starter must be reset. Resetting the soft starter can be done by disconnecting
and reapplying AC power (power-off reset), by pressing the “O/RESET” key (manual reset), automatic reset, or via digital
inputs. For details on Reset and a full list and description of Fault Codes, please read Chapter 6 in the SSW07 User’s
Guide.
Trim-pots and DIP switches:
When a fault is detected, the soft starter is disabled and the Fault Code is displayed by flashing LED’s. To restart the soft
starter after a fault has occurred, the soft starter must be reset. Resetting the soft starter can be done by disconnecting
and reapplying AC power (power-on reset), by pressing the “RESET” button on the front panel (manual reset), automatic
reset, or via digital inputs. For details on Reset and a full list and description of Fault Codes please read Chapter 6 in the
SSW07 User’s Guide.
