diameter of the battery cables are appropriate. Check that the battery connections are good and that the battery is fully charged. If the cables are sized correctly, the connections are good, and the battery is charged, but the voltage still drops below 11 volts, you may need to use a larger battery.

USB Loads

Alot of USB-powered devices such as portable music (MP3) players, mobile phones, and video game players can be charged and powered safely via the standard USB port. However, some devices such as portable GPS receivers and certain cameras may not work and even cause damage even if you use the USB cable that came with the product. Be sure that the device only accepts 5 volts and can be charged or powered using other sources of power. See the device’s owner’s guide under specifications for information.

Exceptional Loads

Some induction motors used in freezers, pumps, and other motor- operated equipment need high surge currents to start. The PROwatt SW Inverter may not be able to start some of these motors even though their rated current draw is within the inverter’s limits.

If a motor refuses to start, observe the VOLTS indicator while you are trying to start the motor. If the indicator drops below 11 volts while the PROwatt SW Inverter is trying to start the motor, this may explain why the motor won’t start. Make sure the length and

Battery Charging Frequency

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. For information about battery chargers, see our web site at www.xantrex.com.

Maintenance

Routine maintenance is required to keep your PROwatt SW Inverter operating properly. Periodically you should:

•Clean the exterior of the unit with a damp cloth to prevent the accumulation of dust and dirt.

•Tighten the screws on the DC input terminals.
