Use an appropriate crimping toolor solder the wires directly into the provided insunsulatedfastons. Use minimal 10mm spacersbetween the PCB and the mounting plate and keep a minimum distance of 10mm aroundthe PCB.Prevent accidental touching of the PCB (solder side). Make sure the mains is disconnectedwhen working on the Softstart.WarningTO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSETHIS PRODUCT TO RAIN OR MOISTURE.DescriptionTransformer inrush current is limited by means of a triac switching heavy-duty resistors inseries with AC mains prior to relay switching. With an optional (bicolour) LED the status“On” or “Standby” can be indicated. In “Standby” the power-consumption will be less then1.2W. The Softstart can operate with either a pushbutton or a switch (jumper selectable). Ifadditional thermal protection is required a PTC-option is selectable. The Softstart canswitch multiple transformers up to a total maximum of 1500VA. Maximum continuouscurrent must not exceed 6A.R3 1

Softstartmodule will switch on right after the mains power isapplied. The Softstart will switch off after mains power isswitched off.Two LED’s (connected anti-parallel) indicate the state ofthe Sofstart depending on the position of the switch.Switch closed: Softstart is in standby. LED1 is lit.Switch opened: Softstart is switched on. LED2 is lit.Fig4bThis switch can be a low voltage, low current type.Jumper set to pushbutton/LED indication mode with PTCtemperature monitoring. Depending on the type of PTCused the Softstart will switch off in case of anovertemperature.Under normal conditions PTC monitoring is not necessaryFig4cR3 2
