Assembly (Skipping this can lead to troubles ! )

Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

Make sure you have the right tools

A good quality soldering iron (25- 40W) with a small tip.
Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and en-ables you to make good connections. When solder rolls off the tip, it needs cleaning.
Thin raisin-core solder. Do not use any flux or grease.
A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot fly towards the eyes.
Needle nose pliers, for bending leads, or to hold components in place.
Small blade and Phillips screwdrivers. A basic range is fine.

For some projects, a basic multi-meter is required, or might be handy

Assembly Hints

Make sure the skill level matches your experience, to avoid disappointments.
Follow the instructions carefully. Read and understand the entire step before you perform each operation.
Perform the assembly in the correct order as stated in this manual
Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
Values on the circuit diagram are subject to changes.
Values in this assembly guide are correct*
Use the check-boxes to mark your progress.
Please read the included information on safety and customer service
Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

Soldering Hints

Mount the component against the PCB surface and carefully solder the leads

Make sure the solder joints are cone-shaped and shiny

Trim excess leads as close as possible to the solder joint

AXIAL COMPONENTS ARE TAPED IN THE CORRECT MOUNTING SEQUENCE !

Construction

Hook– up and use

Solder an AC cable to the SK1 pins (AC Power).
Solder the cables of the lampholder to the appropriate pins “SK2”(LOAD), use always min. ø 0,75mm² cable.
As this kit is shipped to different countries, their is no AC plug supplied. You will need to attach a plug that matches your electrical system. You can adjust the ON/OFF time by turning the trimmer RV1 “OFF” and RV2 “ON”. The ON/OFF LEDs indicate the LOAD status.
FThe connection cables should be equipped with a good strain relief when mounted in a movable housing. FOptional you can mount a heatsink on TR1 (e.g. ML73/25P) so that Max. power is 600W at 240VAC and 300W at 110VAC.

Inspect the complete assembly once more before applying power to the unit !
