Fault Indicator – an at-a-glance LED that comes on to indicate an inverter fault (see Section 4.0 for troubleshooting). USB Port – allows USB-enabled devices to be powered and charged. ON/OFF Power Switch – a 2-position switch that turns the inverter on and off.
1.0 Introduction The back panel of the CSW412 inverter is equipped with the following features (see Figure 1-5): 8. Cooling Fan – an intake cooling fan that automatically turns on when the inverter’s internal temperature rises above 122 °F (50 °C). The fan turns off when the inverter’s internal temperature falls below 122 °F (50 °C). 9. DC Negative Terminal (black) – the inverter’s connection to the negative terminal on the 12 VDC battery bank. 10.
2.0 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.

2.0 Installation 2.2 Locating and Mounting the Inverter WARNINGS: • Do not mount the inverter near any flammable or combustible fluid or components. • Provide adequate clearance/ventilation to the inverter. Do not cover or obstruct any air vent openings and/or install in a zeroclearance compartment.
2.0 Installation For Indoor Use: Flat on a horizontal surface (right side up or upside down). DC terminals to the right, left or the top. Note: The CSW inverter cannot be mounted with the DC terminals facing down. For RV Installation: Mount flat on a horizontal surface only Figure 2-3, Approved Mounting Positions 6.3’’ (16.1 cm) Top 6.9’’ (17.5 cm) 5.8’’ (14.7 cm) 7.9’’ (20 cm) Front (AC Side) Back (DC Side) 3.4’’ (8.

2.0 Installation 2.3 Wiring the Inverter – General Requirements This section describes the requirements and recommendations for wiring the CSW 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 • • • • • All conductors that are at risk for physical damage must be protected by tape or placed in a raceway.
2.0 Installation 2.4 DC Wiring This section describes the inverter’s required DC wire sizes, the recommended disconnect/overcurrent protection, and how to make the DC connections to the inverter and the battery bank. WARNING: Even though DC voltage can be regarded as “low voltage”, significant hazards may be present, particularly from short circuits of the battery system.
2.0 Installation 2.4.1 DC Wire Sizing It is important to use the correct sized DC wire to achieve maximum efficiency from the system and to reduce fire hazards associated with overheating. Always keep your wire runs as short as practical to prevent low voltage shutdowns and to keep the DC breaker from nuisance tripping (or open fuses) because of increased current draw. See Table 2-2 to select the minimum DC wire size (and corresponding overcurrent device) required based on your inverter model.
2.0 Installation 2.4.2 DC Overcurrent Protection For safety reasons and to comply with electrical code regulations, DC overcurrent protection must be provided as part of the installation. The DC overcurrent protection device must be installed in the positive DC cable line, it can be a fuse (with a disconnect switch) or a circuit breaker and must be DC-rated.
2.0 Installation 2.4.5 Wiring the Battery Bank WARNING: Lethal currents will be present if the positive and negative cables attached to the battery bank touch each other. During the installation and wiring process, ensure the cable ends are insulated or covered to prevent touching/shorting the cables.
2.0 Installation 2.4.7 Wiring the Inverter to the Battery Bank CAUTION: The inverter is NOT reverse polarity protected—if the positive terminal of the battery is connected to the negative terminal of the inverter and vice versa, severe damage to the inverter will occur and this will void the warranty. Before connecting the DC wires from the batteries to the inverter, verify the correct battery voltage and polarity using a voltmeter.

2.0 Installation 2.5 Testing the Inverter Before proceeding, you must first 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. 2.5.1 Inverter Functional Test After all electrical connections to the inverter and batteries have been completed, plug a small AC load (e.g.
3.0 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 pure 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.
3.0 Operation 3.2 CSW1012 and CSW2012 Operation The CSW1012 and CSW2012 inverters use a front panel that contains a power/select button, a status indicator, a digital display for viewing system status, a remote port, a USB port, and a GFCI AC output receptacle. Turning the Inverter on and off The Power/Select button is used to turn the inverter on and off. To turn the unit on, press and hold the button for 1 second until you hear a “beep”.
3.0 Operation 3.3 Understanding Loads The inverter can power most loads within its power rating, however, there are special conditions that can cause a load to behave differently than expected. Following are some common problems encountered when using this inverter. USB loads – When using the USB connector, be sure that the device you will be connecting will accept 5 volts (≤ 750mA) and can be charged or powered using another power source.
4.0 Troubleshooting 4.0 Troubleshooting Use Table 4-1 to troubleshoot your inverter. For CSW1012 or CSW2012 inverters, also use Table 4-2 to view 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 No AC output. Status indicator is off. Solution The unit is off. Turn on the unit. See Operation instructions. No power to inverter.
