    Utilization category is AC-53a or AC53b, Form 1. For further information, see Technical Specification. Warnings 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.

  • Page 4: General

    GENERAL 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.

  • Page 5: By- Pass

    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.

  • Page 6: Wiring Notes

    6 • Installation 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. INSTALLATION Do not interchange line and load connections WARNING! Prior to Installation Check that Motor’s Full Load Ampere (FLA) is lower than or equal to the starters Full Load Current (FLC).
