3. Installation 3.1 Mounting The Mini-Mite Ferro Power Supply is designed to be wallmounted using the provided bracket. INSTALLATION PROCEDURE: 1. A minimum clearance of 1.75” should be allowed above, below, and along the sides and front of the unit for adequate cooling. 2. Attach mounting bracket in desired location. 3. Mount on the mounting bracket as required. Slide the Mini-Mite into position on the bracket.
3. Installation 3.2 Electrical Connections 1. Remove the front cover with the key provided. 2. Install the output cable connector in the chassis adapter provided on the bottom of the cabinet. 3. Plug the AC line cord into a 120Vac utility receptacle. 4. If desired, a direct earth ground may be connected using the small copper lug on the bottom of the unit. 5. Replace the cover. The Mini-Mite is now operational. 3.3 Disassembly DISCONNECTION PROCEDURE: 1. Unplug the unit from the utility outlet. 2.
4. Operation 4.1 Changing the output voltage (PSF-MMP-AXX only) The Lectro Mini-Mite Ferro Power Supply is designed to provide regulated 30V or 60V from the 120Vac power line. The power output is normally configured for 60V and can be changed to provide 30V via the following procedure. 60V – 30V CONVERSION PROCEDURE 1. Verify AC is disconnected. 2. Cut yellow wire 2” from end of heat shrink tubing, strip 1/ 2” from end. 3. Remove the wire nut from the blue wire, twist ends of Yellow, Blue wires together.
4. Operation 4.2 Service CAUTION Lethal voltages are present within the chassis when the unit is in operation. For safety, be certain to unplug the input cord and the output cable connector before attempting service. NOTE Part of the unit’s thermal design is heat conduction from the transformer brackets to the cabinet of the power supply. A thin coating of silicone grease is applied to the bracket contact area during manufacture.
4. Operation 4.3 Maintenance Proper operation and longer system life can be ensured by performing the following maintenance: 1. Before opening the cabinet, inspect it for external damage or tampering, including the grounding circuit. 2. Unlock and open the cabinet. 3. Inspect the air vents for obstructions 4. Inspect the connectors and cable for damage or corrosion. 5. Close and relock the cabinet. CM003101 Rev.
