supplier or your warranty will be void.
•To prevent overheating of the battery bank, keep all
ventilation openings free from obstruction. Keep the
battery bank front/rear panel 20 cm away from the wall.
•Make sure the battery bank is installed within the
proper environment as specified. (0~40°C/32~104℉
and 30-90%RH non-condensing)
•Do not install the battery bank at outdoor sites; this
battery bank is designed for indoor use only.
•This battery bank is not designed for use in dusty,

•CAUTION –Risk of electric shock –Battery circuit is
not isolated from AC, hazardous Voltage may exist
between battery terminals and ground. Test before
touching with bare hands.
•CAUTION –A Battery can present a Risk of Electrical
Shock and High Short Circuit Current. The Following
Precaution Should be Observed When Working on
Batteries:
A. Remove watches, rings, or other metal wearing
objects.
B. Use tools with insulated handles and wear rubber
gloves and boots.
C. Do not lay any metal tools or parts on top of
batteries.
