Clipper Instructions The MNCLIPPER works alone or with the MidNite Solar Classic MPPT Charge Controller to provide the highest level of performance and protection possible. Features: Helps protect turbine from overspeed. Braking feature included. Convenient switching between run / turbine slowing. Settable voltage threshold for clipping. 50 Amp pass-through. D.C. or Three Phase AC models with heavy duty three phase bridge rectifier. Converts AC input to D.C.
Clipper Instructions (continued) IMPORTANT SAFETY INSTRUCTIONS SAVE THESE INSTRUCTIONS - These instructions contain important safety and operating instructions for the MidNite Solar MNClipper. If you do not fully understand any of the concepts, terminology, or hazards outlined in these instructions, please refer installation to a qualified dealer, electrician or installer. These instructions are not meant to be a complete explanation of a renewable energy system.
Clipper Instructions (continued) Theory of operation: The Clipper protects charge controllers and other electronics by sensing the incoming voltage from the turbine and using its internal loads as needed to hold down the incoming voltage to a value that you set. When used with a Classic MPPT charge controller, the Classic uses its auxiliary output to control the Clipper to provide optimum performance.
Clipper Instructions (continued) INSTALLATION: Mounting the MNClipper: Mounting the MNClipper is not a difficult task but a little planning now can save a lot of grief later. It is recommended that you read and fully understand all the installation instructions and safety precautions before proceeding. Parts Included are: 1 - MNClipper 2 - Mounting brackets 4 - 6mm Threadforming screws 1 - Instruction manual Tools required for mounting the MNClipper are: #2 Phillips screwdriver, stud finder and a level.
Clipper Instructions (continued) Use a level and hold the top mounting bracket on the wall in a horizontal position and mark on the wall where the mounting screw holes will be placed. If required, drill pilot holes using a #10 (0.193” diameter) drill bit. Drill appropriately sized holes for anchors (sold separately) when installing on non-wood surfaces. Secure the top mounting bracket to the wall using three ¼ X 1½ hex-head lag bolts. Make sure that the outer two lag bolts are securely fastened into a stud.
Clipper Instructions (continued) Clipper Bottom Knockout Location Clipper Side Knockout Location Clipper Dimensions: 25.411 Tall X 15.41 Wide 26.961 Tall including mounting brackets Shipping Weight 55 lbs.
Clipper Instructions (continued) AC Clippers: Connect phases 1, 2 and 3 from the turbine to the corresponding lugs on the large terminal block at the lower right of the Clipper. Knockouts are located on the sides and bottom of the Clipper. Three phase input from turbine Terminal block accepts 2/0-14 AWG wire.
Clipper Instructions (continued) DC Clippers: Connect the positive and negative output from the turbine to the positive and negative inputs on the PCB terminal block TB2. It is the two position terminal block marked “Bridge Rect”. Be sure to observe proper polarity. TB2 Connect DC output from turbine here. Terminal block accepts 6-20 AWG wire. Observe polarity.
Clipper Instructions (continued) Controlling the Clipper with a Classic Charge Controller. The Classic charge controller has a PWM (Pulse Width Modulation) output that can be used to control the Clipper’s output voltage. This will provide very precise control of the power being produced. Refer to the “Configuring Auxiliary Input/Output” section in the Classic manual for settings and connections for the Classic.
Clipper Instructions (continued) Exchanging the Resistor Module: The Clipper comes with a replaceable diversion load. The diversion load is a resistor module available with different resistor values and configurations to provide a variety of possible loads. To replace/exchange the resistor module first remove all power to the Clipper and allow it to cool. AC Models: AC models come with the load resistors for each phase wired either in series or parallel, there are also multiple values for resistors.
Clipper Instructions (continued) DC Models: DC models come prewired to provide various loads. Verify that the new module is of the desired resistance before beginning installation. Step 1. Remove the two wires to the temperature sensor on the side of the resistor module. Remove the terminals by pulling on the red handles. Do not pull on the wires. Step 2. Remove the two wires from the terminal block at the base of the resistor module. Do not remove the wires that go inside the module. Step 3.
