3.While operating the AC product you can check the level of the battery as detailed in Figure 2-2, “Battery level Indicator” on page 2–6.This will tell you the approximate charge level of the battery and whether you are approaching the point when recharging is required.
4.As the battery pack becomes nearly discharged, or “empty”, a low voltage warning will sound. This will give you time to shut down a computer, for example. If this warning is ignored, the inverter will switch off automatically a few minutes later to prevent battery damage. See below - Automatic Protection: Overload, Overheating and Low Battery for details.
5.Fully recharge XPower 1500’s battery pack as soon as possible after each use. See “Recharging XPower 1500” on page 2–16.
Automatic Protection: Overload, Overheating, and Low Battery
XPower 1500 has built-in protection against output overload and from overheating. If an AC product rated higher than 1350 watts (or which draws excessive surge power at start up) is connected, or if the inverter exceeds a safe temperature, it will automatically shutdown. The green POWER light will go off and the red FAULT light will switch on. To reset, unplug the product and turn the AC Outlets Switch off for 5 seconds, then turn it back on. Normal operation should resume. If not, turn the AC Outlets Switch off again and allow XPower 1500 to cool for several minutes. While AC power is off, press the Battery Status Switch to make sure the charge level is sufficient.
If the battery pack is allowed to discharge excessively, damage may occur. To prevent this, XPower 1500 has a built-in audible warning that alerts you when the battery pack is nearly discharged and that recharging is needed. If this warning is ignored, XPower 1500 will automatically switch off the AC Outlets and the red FAULT light will illuminate when the battery pack reaches “empty”. The FAULT light will remain on until the AC Outlet’s Switch is turned off. Promptly recharge XPower 1500 to help maintain the internal battery pack. See “Recharging XPower 1500” on page 2–16.
