1. INTRODUCTION 3. How an Inverter/Charger Works An inverter takes direct current (DC) from your batteries and turns it into alternating current (AC), exactly like you use at home. It also takes alternating current when your motor coach is connected to shore power and transforms it into direct current to recharge your batteries.

2. INSTALLATION 1. Unpacking and Inspection Carefully remove the ME Series inverter from its shipping container and inspect all contents. If items appear to be missing or damaged, contact Magnum Energy at (425) 353-8833 or your authorized Magnum Energy dealer. If at all possible, retain the shipping container in the event the unit ever needs to be returned for factory service. ATTENTION: Electrostatic Sensitive Devices. Observe precautions for handling. 2.
2. INSTALLATION 2. Pre-Installation, continued Hardware / Materials Required Conduit, strain-reliefs and appropriate fittings 1/4" mounting bolts and lock washers Electrical tape Wire ties Tools Required Misc screw drivers Drill and drill bits Level Level Pliers Pencil or Marker 1/2" wrench Wire strippers Multimeter Wiring Pre-plan the wire and conduit runs. For maximum safety, run both AC and DC wires/cabling in (separate) conduit.
2. INSTALLATION 2. Pre-Installation, continued Torque Requirements Torque all AC wiring connections to 16 inch pounds. Torque DC cable connections to 10-12 foot pounds. AC Main Panel If the installation will be powering a wide-range of appliances throughout the vehicle, an AC main panel is often recommended.

2. INSTALLATION 3. Installation NOTE: Read all instructions and cautionary markings located at the beginning of this manual and in the pre-installation section, before installing the inverter and batteries. CAUTION: Do not mount the inverter or the batteries near the vehicles gasoline or propane fuel tanks. Mount the inverter only on a non-combustable surfaces. Maximum abient temperature MUST NOT exceed 113 °F (45 °C). For Canadian installations, the inverters vents must face downward.
2. INSTALLATION 3. Installation, continued Battery Cables and Sizing Select the correct battery cables for the installation from the table. It is important to use the correct cable to achieve maximum efficiency from the system and reduce fire hazards associated with overheated cables. Undersized cables can also lower the inverters peak output voltage as well as reduce its surge power capability. Long cable runs also reduce efficiency due to resistance in the cable.
2. INSTALLATION 3. Installation, continued Battery Wiring WARNING: During the installation and wiring process, cover exposed battery cable ends with electrical tape to prevent shorting the cables. NOTE: DO NOT connect the positive cable to the inverter at this time. Depending upon the type of battery you use in the installation (6 or 12 VDC), the batteries must be wired in series, parallel or series/parallel to provide 12 VDC.

2. INSTALLATION 3. Installation, continued Series Connection (four 6 VDC batteries to create a 24 VDC bank) A series connection combines overall battery voltage by the number of batteries in the string. Even though there are multiple batteries, the capacity remains the same. In the example at the left (Figure 8), four 6 VDC, 100 AHr batteries are combined into a single string resulting in a 24 VDC, 200 AHr bank.

2. INSTALLATION 3. Installation, continued DC Fuse Block A fuse or circuit breaker must be located within 18 inches of the battery to protect the DC wiring system. The device must be rated to match the size of the cable, but can be rounded up to the next larger size (i.e., a cable rated at 150 amps can accept a 175 amp fuse) as necessary. Mount the fuse block (or circuit breaker assembly) as near as practical to the batteries.
