HDS650 (HDS 650) Karcher Pressure Washer

Hi Greg, thank you for contacting us. We have found some relevant instructions for you to wire the inlet contractor. They may not be of the exact same model, but they will help you with the process. You may follow the following steps: 1. Make sure that the contacts of the contactor are rated in both voltage and current to handle the expected load that will be required by the equipment being powered. 2. The manufacturer information will identify the 2 input pins for 120 volts of AC control. They may be 2 or more sets of output contacts identified. These contacts may be indicated on the label as normally open (NO) and normally closed (NC). 3. Some contractors provide an auxiliary output contact as a signal to the isolated part of the circuit where the contactor has been energized. This auxiliary contact will not be rated at the higher voltage. Instead, it should be rated at 120 volts AC. 4. Remove all power to the wires. Run all input and output wires to the contactor. These wires should be rated in the manufacturer's information. Use wire strippers to cut the excess length off of the ends of the wire, making sure that the wires are long enough to reach the intended contact. 5. Use the wire strippers to strip a half inch (13 mm) from the ends of each wire. If the wire is stranded, twist the exposed wire to ensure that no strands are left hanging. Stray strands may make unintended contact with a piece of equipment and cause damage. 6. Use a screwdriver to loosen the holding screws in the contact blocks for the wires. Insert the wires only so far that no insulation is pushed into the contact area of the block. Make sure that no stray strands are jutting out from the contact block. Tighten the screws on the contact blocks. 7. Apply the control voltage to the input. Listen for the contactor to click as it engages. De-energize the contactor. 8. Put the stripped end of each wire into the appropriate contact block after loosening the screw of the block. Make sure that no stray strands of wire are jutting from the contact blocks. Tighten down the screws of the contact blocks. We hope this information is useful!
