1 Introduction Thank you for purchasing the PowerBright® XR400/750 Connected to the 12 volt outlet in your vehicle, the XR400/XR750 efficiently and reliably powers a widevariety of loads through both the AC outlet and USB port. Read this guide before connecting or using the XR400/750 and save it for future reference. We hope you enjoy using your XR400 / XR750 and if you require any assistance, please contact our help desk: www.PowerBright.com or toll free: 1.866.295.
Warnings and Cautions The XR400 / XR750 housing may become uncomfortably warm, reaching 140° F (60° C) under extended high power operation. During operation, keep it away from materials that may be affected by high temperatures. Do not use the XR400 / XR750 in the presence of flammable fumes or gases, such as in the bilge of a gasoline powered boat, or near propane tanks. Do not use the XR400 / XR750 in an enclosure containing automotive-type, lead-acid batteries.
CAUTION: Risk of Fire. Do not replace any vehicle fuse with a rating higher than recommended by the Vehicle Manufacturer. Ensure that the electrical system in your vehicle can supply this product without causing the vehicle fusing to open. This can be determined by making sure the fuse in the vehicle which protects the outlet is rated higher than 8 amperes. Information on the vehicle fuse rating is typically found in the vehicle operator’s manual.
CAUTION: Output non-sinusoidal Some chargers for small nickel-cadmium batteries can be damaged if connected to the XR400 / XR750 Do not use the inverter with the following appliances: • Small battery-operated appliances like rechargeable flashlights, some rechargeable shavers, and night lights that are plugged directly into an AC receptacle to recharge. • Battery chargers used in hand power tools.
Additional Safety Guidelines • Do not insert foreign objects in the XR400/750 outlets or other openings. • Never connect the inverter to power utility AC distribution wiring. • Do not use the XR400/750 in temperatures over 100° F (40° C). • Do not expose the XR400/750 to water, rain, snow, or spray. Failure to follow these safety guidelines may cause personal injury and/or damage to the XR400/750 It may also void your product warranty.

5 Using the Inverter Through its AC outlet, theXR400/750 is capable of powering most 120V AC products that use 400W/750W or less. The XR400/750 can also power or charge most consumer electronics that have USB power ports. The XR400/750 AC output waveform, called “modified sine wave” is designed to function similarly to the sine wave shape of utility power.
CAUTION: Reverse polarity damage When plugging in the DC cable, ensure that the plug aligns with the DC cable port. Failure to do so will result in reverse polarity and a blown fuse. 1. Plug a DC cable into the DC cable port on the XR400/750 and connect to a 12V battery. Observe correct polarity. 2. Plug the device you want to operate into the XR400/750 When the inverter is not in use, unplug it from the 12V outlet to prevent slight discharge of the battery. 3.
6 Inverter Operation 1. 2. When properly connected to a 12V outlet, and when the ON /OFF switch is in the ON position, the light will glow BLUE, indicating the inverter is ready. Plug the product(s) you want to operate into the AC outlet or USB port and switch them on (if necessary). Operating Guidelines • 8 As the battery is used, its voltage begins to fall. When the XR400/750 senses that the voltage at its DC input has dropped to 10.
Important: Vehicle batteries are designed to provide brief periods of very high current needed for engine starting. They are not intended for constant deep discharge. Regularly operating the XR400/750 from a vehicle battery until low-voltage shutdown occurs will shorten the life of the battery. • • • If an AC product rated higher than 400/750 is plugged into the XR400/750, the inverter will shut down. The RED FAULT light comes on.
CAUTION Although the XR400/750 incorporates protection against over-voltage, it may still be damaged if the inputvoltage exceeds 16 V. • In the event of an overload, low battery voltage or overheating, the XR400 / XR750 automatically shuts down. Battery Operating Time Operating time will vary depending on the charge level of the battery, its capacity and the power level drawn by the particular AC load, USB load, or combination of both.
Interference with Electronic Equipment Generally, most AC products operate with XR400/750 just as they would with household AC power. Below is information concerning two possible exceptions. Buzzing sound in audio systems and radios Some inexpensive stereo systems and AM-FM radios have inadequate internal power supply filtering and will “buzz” slightly when powered by the XR400 /750. Generally, the only solution is an audio product with a higher quality filter.
7 Troubleshooting PROBLEM: AC product will not operate, no inverter lights are ON. Possible cause Solution Battery is defective. Check battery and replace if required. Loose connections. Check connections. PROBLEM: Measured inverter output is too low. Possible cause Solution Standard “averagereading” AC voltmeter used to measure output voltage, resulting in an apparent reading 5 to 15 V too low. Inverter’s “modified sine wave” output requires “true RMS” voltmeter for accurate measurements.
Possible cause Solution Battery voltage is too low. Recharge battery. PROBLEM: AC product will not operate, RED FAULT light ON. Possible cause Solution AC product(s) connected are rated at more than the inverter’s continuous power rating; overload shutdown has occurred. Use a product with a power rating less than the inverter’s continuous power rating. AC product is rated less than the inverter’s continuous power rating; high starting surge has caused overload shutdown.
