Mini Meter Installation Manual 3. Installation Instructions The following section contains installation and wiring instructions for the Leviton Mini Meter™. If technical assistance is required at any point during the installation, contact information can be found at the end of this manual. Leviton is not responsible for damage to the meter caused by incorrect wiring. 3.1. Explanation of Warning Symbols Indicates the need to consult the operation manual due to the presence of a potential risk.
Mini Meter Installation Manual 3.3 Preparation 1. Verify the model number and electrical specifications of the device being installed to confirm they are appropriate for the intended electrical service (see Section 2). 2. Consult local codes for any possible permits or inspections required before beginning electrical work. 3. Ensure the conduit for the installation is flexible and non-metallic. For outdoor applications conduit and conduit fittings must be rated for UL Type 4x outdoor enclosures.
Mini Meter Installation Manual 3.5.2 Drilling Conduit Holes The bottom panel and lower half of the side panels work best for conduit opening locations in outdoor single meter enclosures. Select the location the makes wire installation easiest for the given environment. If the side panels are used, holes should be centered approximately half an inch from the bottom of the enclosure. Hole sizes must be appropriate to fittings, and large enough to fit all voltage and CT wiring (4-7 18 AWG min.
Mini Meter Installation Manual 3.6 Installation of Voltage Lines 1. Field wired voltage connections are made to the Mini Meter terminal block. The rated torque for these terminal blocks is 4.4 in-lb, and can be used with solid and stranded copper wires, at 12-18 AWG. 2. Verify that branch circuit fuse specifications meet local electric codes. 3. Connect 18 AWG min., 300 V min.
Mini Meter Installation Manual General Requirements: Splices on the CT leads must be within the meter enclosure, not inside the conduit. Leviton provided CT leads are 24 inches minimum. Wire insulation should be stripped so that the bare conductor length that connects to the meter terminal block does not exceed 0.300 inches. CTs should be securely fastened such that they will not slide down to live terminals.

Mini Meter Installation Manual 3.9 Testing the Installation Testing Voltage The power LED illuminates when the Mini Meter or Epoxy Encapsulated Module has a proper power supply. Voltage should also be tested using an AC Voltmeter to verify that the voltage across voltage line terminals (L1 to Neutral and L2 to Neutral) is not in excess of the maximum rated voltage. CT Reverse Phase Indicator Mini Meters and EE Modules have a red reverse phase indicator LED as described in section 2.3.
Mini Meter Installation Manual 4. Maintenance Properly installed meters with sound connections and secure conduit fittings should not require user maintenance. If the meter is functioning abnormally, consult the FAQ/Troubleshooting guide. If the answer cannot be found there, contact Leviton technical support. 5. Troubleshooting/FAQ Problem Solution 1. Power LED not illuminated 2. Load LED not flashing 3. Registered consumption low 4.
