Installation： Where to install.
3-4-6. Close to batteries – Avoid excessive cable lengths but do not install the Inverter in the same compartment as batteries. Use the recommended wire lengths and sizes (see section 3-5). Also do not mount the Inverter where it will be exposed to the gases produced by the battery. These gases are very corrosive and prolonged exposure also will damage the Inverter. WARNING! Shock Hazard.
3-6. AC Safety Grounding： The AC output ground wire should go to the grounding point for your loads ( for example, a distribution panel ground bus ). 3-6-1. Neutral Grounding (GFCI'S)： 3-6-1-1. 110V models：The neutral conductor of the AC output circuit of the Inverter is automatically connected to the safety ground during inverter operation.
Ground Fault Circuit Interrupters (GFCI)： Installations in Recreational Vehicles (for North American approvals) will require GFCI protection of all branch circuit connected to the AC output of the hardwire terminal equipped Inverter.In addition, electrical codes require GFCI protection of certain receptacles in residential installations.
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 a. Blinking fast Over input voltage. ( OVP ) Check input voltage. Reduce input voltage. b. Blinking slow. Low input voltage. ( UVP ) Recharge battery. Check connections and cable. c. Blinking Intermittently. Thermal shutdown. ( OTP ) Improve ventilation.
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. Warranty： We warrant this product against defects in materials and workmanship for a period of 36 months from the date of purchase and will repair or replace any defective Power Inverter when directly returned, postage paid, to us.
