    3-4. Installation Where to install. The power inverter should be installed in a location that meets the following requirements: 3-4-1. Dry － Do not allow water to drip or splash on the inverter. 3-4-2. Cool － Ambient air temperature should be between 0˚C 3-4-3.
  • Page 13 The longer or narrower the cables, the greater the voltage drop. Increasing your DC cable size will help improve the situation. Model No Wire AWG Inline Fuse SA-1500-112 200A SA-1500-124 130A WARNING! The installation of a fuse must be on positive cable.
  • Page 14 Also, use only high quality copper wiring and keep cable length short, a maximum of 3- 6 feet.

  • Page 15: Ac Safety Grounding

    3-6. AC Safety Grounding During the AC wiring installation, AC input and output ground wires are connected to the inverter. The AC input ground wire must connect to the incoming ground from your AC utility source. The AC output ground wire should go to the grounding point for your loads (for example, a distribution panel ground bus).

  • Page 16: Inverter Operation

    3-7. Inverter Operation To operate the power inverter, turn it on by using the ON/OFF switch on the front panel. The power inverter is now ready to deliver AC power to your loads. If you are operating several loads from the power inverter, turn them on separately after the inverter has been turned on.
  • Page 17 WARNING! You may observe a spark when you make this connection since current may flow to charge capacitors in the power inverter. Do not make this connection in the presence of flammable fumes Explosion or fire may result. 3-7-5. Set the power switch to the ON position. Check the meters and indicators on the front panel of the inverter.

  • Page 18: Power Output

    3-8. Power output: The inverter will operate most AC loads within its power rating. When deeming whether a microwave oven can be operated by the inverter, remember that the power commonly advertised for microwave ovens are the cooking power (the power delivered to the food) not the power actually consumed by the microwave oven.

  • Page 19: Troubleshooting Guide

    4. Troubleshooting guide WARNING! Do not open or disassemble the Inverter. Attempting to service the unit yourself may result in a risk of electrical shock or fire. Problems and Symptoms Possible Cause Solutions Low output voltage Using average reading Use true RMS reading meter and cable.

  • Page 20: Maintenance

    5. Maintenance Very little maintenance is required to keep your inverter operating properly. You should clean the exterior of the unit periodically with a damp cloth to prevent accumulation of dust and dirt. At the same time, tighten the screws on the DC input terminals. 6.
