Safety & Warnings• 3
1. SAFETY & WARNINGS
1.1 Safety
1
Read this manual carefully before operating the equipment and follow its
instructions.
2
Installation, operation and maintenance should be in strict accordance with this
manual, national codes and good practice.
3
Installation or operation not performed in strict accordance with these
instructions will void manufacturer’s warranty.
4
Disconnect all power inputs before servicing the soft-starter and/or the motor.
5
After installation, check and verify that no parts (bolts, washers, etc) have fallen
into the starter.
1.2 Attention
1
This product was designed for compliance with IEC 947-4-2 for class A
equipment.
2
Use of the product in domestic environments may cause radio interference, in
which case, the user may be required to employ additional mitigation methods.
3
Utilization category is AC-53a or AC53b, Form 1.
4
For further information, see Technical Specification.
1.3 Warnings
1
Internal components and P.C.Bs are at mains potential when the SOLSTART-1P
is connected to mains. This voltage is extremely dangerous and will cause death
or severe injury if contacted.
2
When SOLSTART-1P is connected to mains, even if control voltage is
disconnected and motor is stopped, full voltage may appear on starter’s output
and motor’s terminals. Therefore, for isolation purposes it is required to connect
an isolating device (C/B, switch, etc) upstream to the SOLSTART-1P.
3
The starter must be grounded to ensure correct operation, safety and to prevent
damage.
4
Check that Power Factor capacitors are not connected to the output side of the
soft starter.
5
Do not interchange line and load connections
The company reserves the right to make any improvements or modifications to its products without prior notice and does not
guaranty any data in its preliminary publishments .

2. GENERAL
2.1 Introduction
The SOLSTART-1P is a Miniature Analogue soft starter which incorporates a thyristor to start a single phase squirrel cage
induction motor. By supplying a slowly increasing voltage, it provides soft start and smooth step-less acceleration, while drawing
the minimum current necessary to start the motor.
After the acceleration is completed a bypass is energized, supplying the motor its full voltage.

2.4 Starter Selection
The starter should be selected in accordance with the following criteria:
2.4.1 Motor current & Starting Conditions
Select the starter according to motor's Full Load Ampere (FLA) - as indicated on its nameplate (even if the motor will
not be fully loaded).
The SOLSTART-1P is designed to operate under the following maximum conditions:

For other starting conditions – consult factory
2.4.2 Mains Voltage (line to line)
220 – 240V (+10% - -15%)
Each starter is suitable for one of the above levels & for 50/60 Hz.
________________________________________________________________________________________________________
General. • 5
2.4.3 By- Pass
30A, 8310VA, 277VAC. (Maximum ratings)
The SOLSTART-1P incorporates a change-over internal by-pass. While starting, the by-pass allows current flow
through the thyristor. At the end of the starting process the by-pass closes and carries the current to the Motor.
The by-Pass is responsible for 2 functions at the end of acceleration:
1. The NO contact closes, shortens soft starter’s thyristor and bypasses it.
2. The NC contact opens and disconnecting the Starting booster (If exist – Consult factory for
utilizing a starter booster)
2.4.4 Starting Voltage adjustment
The SOLSTART-1P incorporates a potentiometer (P15) allows the user to adjust the starting voltage of the motor thus
controlling motor’s current and starting time.
2.4.5 Additional current limiting
In case of high starting current it is possible to add a starting buster to decrease the starting current.
Consult factory for additional information.

Shown below are signal readings with and without the
“SOLSTART-1P”
CAUTION!
Power factor correction capacitors, if any, must not be installed on starter's Load side.
When required, Install capacitors on the Line side.
WARNING!
When Mains voltage is connected to the starter, full voltage will appear on the starter’s
load terminals. Therefore, for isolation purposes it is required to connect an isolating
device (C/B, switch, etc) upstream to the SOLSTART-1P (on the Line Side).
6 • Installation
2.6 Wiring Notes
2.6.1 Short Circuit Protection
The SOLSTART-1P should be protected against a short circuit by Thyristor Protection fuses.
The recommended fuses are: FWP-25B by Bussmann or equivalent.
3. INSTALLATION
WARNING!
Do not interchange line and load connections
3.1 Prior to Installation
Check that Motor’s Full Load Ampere (FLA) is lower than or equal to the starters Full Load Current (FLC).
3.2 Mounting
The starter must be mounted with all four mounting holes.
It is recommended to mount the starter directly on the rear metal plate of the equipment for better heat dissipation.
Do not mount the starter near heat sources.
Protect the starter from dust and corrosive atmospheres
Surrounding air temperature in the cabinet should not exceed 40ºC
3.3 Temperature range & heat dissipation
The starter is rated to operate over a temperature range of 0ºC (32ºF) to + 40ºC(104ºF).
Relative non-condensed humidity inside the enclosure should not exceed 93%.
ATTENTION!
Operating at surrounding air temp. (Inside the cabinet) higher than 40ºC may cause
damage to the starter.
Starter’s heat dissipation while motor is running and the internal bypass is closed is typically less than 0.1 x In (in
watts)
Example
: For an 18A motor, heat dissipation is less than 2 watts while running.

6. SETTING AND STARTUP PROCEDURE
Start the motor and measure the
starting current by a recorder or
by
an oscilloscope
Starting current is
acceptable?
By-pass changes its
position after motor
ends starting?
Rotate potentiometer (P15) c.c.w
by 20º
Consult factory
