Installation 2.0 Installation Review this section and all safety instructions before proceeding with the installation of your inverter. WARNING: Installations should be performed by qualified personnel, such as a licensed or certified electrician. The installer determines which safety codes apply and ensures all applicable installation requirements are followed. Applicable installation codes vary depending on the specific location and application.

Installation 2.3 Wiring the Inverter – General Requirements This section describes the requirements and recommendations for wiring a CMW Series inverter. Before wiring the inverter, carefully read all instructions. WARNING: Wiring should meet all local codes/standards and be performed by qualified personnel (i.e., licensed electrician). 2.3.1 • Wiring Requirements All conductors that are at risk for physical damage must be protected by tape or placed in a raceway.
Installation Refer to Figure 2-7 when connecting the DC wires to the battery, and to Figure 2-8 when connecting to the inverter. Also, consider the following requirements to ensure maximum performance: • The DC positive and negative cables connected to the inverter from the battery bank should be tied together with wire ties/straps or electrical tape approximately every 6 inches (15.3 cm).
Installation DC Wire Size Exception: In an OEM RV application, smaller DC wire (with appropriate overcurrent protection) may be used if the inverter will only be connected to a dedicated load (as shown in Figure 2-2), and the inverter and dedicated load have been thoroughly tested and sold together by the OEM as a complete system. Table 2-2, DC Wire/Overcurrent Device for Rated Use Inverter Model CMW412 CMW1012 CMW1512 Continuous Current (@12.
Installation amps), and has a time delay that allows for momentary current surges from the inverter without opening the fuse. In some installations, if the combined short-circuit current of all the batteries in the bank is determined to be 2,700 amps or less, then an ANL type of fuse may be used—if in doubt, use a Class-T fuse. See Table 2-2 for the fuse size (coordinated with the DC wire size) recommended for your CMW inverter. 2.4.
Installation Depending upon the voltage of the batteries (6 or 12 VDC), the batteries must be wired in series, parallel, or series-parallel to provide the correct voltage. The interconnecting DC wires must be sized and rated exactly the same as those used between the battery bank and the inverter. Place the batteries as close as practical to the inverter, preferably in an insulated and ventilated enclosure. Allow adequate space above the batteries to access the terminals and vent caps (as applicable).
Installation 4. 5. 6. 7. 8. 9. Connect a short wire (same rating as the DC wires) to the other side of the DC circuit breaker (or one end of the fuse/disconnect assembly) and the other end of that short wire to the positive terminal of the battery bank (see Figure 2-1 or Figure 2-2 for reference). This is essential to ensure even discharging across the entire battery bank.
Installation 2.5 Testing the Inverter Before proceeding, test whether the inverter was successfully installed. Use the functional test below to test the inverter, and then perform the GFCI test that follows to ensure the protection device is functioning properly (if applicable). 2.5.1 Inverter Functional Test After all electrical connections to the inverter and the batteries have been completed, plug a small AC load (e.g.
Operation 3.0 Operation When the inverter is properly connected to batteries and turned on, the direct current (DC) from the batteries is transformed into a modified sine wave alternating current (AC). This AC is similar to the voltage provided by your utility and is used to power any electrical appliances (i.e., AC loads) connected to the inverter’s output. 3.1 CMW412 Operation The CMW412 inverter has a front panel that contains a power on/off switch, two LED indicators, and two AC outlets.
Operation Status Indicator The Status LED indicator on the front panel may light green, amber, or red to indicate the inverter’s status. When the status indicator lights: • Green – the inverter is operating normally. • Amber – a warning has been detected. The inverter will shut down at any time. Check the error code on the digital display. • Red – an error has been detected and the unit has shut down. Check the error code on the digital display.
Operation Motor loads not starting – Some appliances, particularly those with induction motors, require a much higher start-up surge than they do when running. Pumps, freezers and refrigerators (compressors) are the most common. The inverter may not be able to start some of these appliances even though their rated current draw is within the inverter’s limits.
Operation 3.4 System Maintenance Battery Charging When possible, recharge your batteries when they are about 50% discharged or earlier. This gives them a much longer life cycle than recharging when they are almost completely discharged. WARNING: Prior to performing these checks, switch both the AC and DC circuits off. • • • • • • • • Visually inspect batteries for cracks, leaks, or swelling—replace if necessary.
Troubleshooting 4.0 Troubleshooting Use Table 4-1 to troubleshoot your inverter. For CMW1012 or CMW1512 inverters, also use Table 4-2 while viewing the unit’s digital display to determine what condition triggered the error/warning code, and what corrective action is needed. Table 4-1, Troubleshooting Guide Problem Symptom Solution The unit is off. Turn on the unit. See Operation instructions. No power to inverter. Check if DC fuse or disconnect switch (if installed) is either blown or turned off.
