General Precaution

1.2.1 Do not expose STM250 to dust, rain, snow or liquids of any type,it is designed
for indoor use. DO NOT block off ventilation, otherwise the INVERTER would
be overheating.
1.2.2 To avoid fire and electric shock, make sure all cables selected with right
gauge and being connected well. Smaller diameter and broken cable are not
allowed to use.
1.2.3 Please do not put any inflammable goods near to inverter.
