1-1. General Safety Precautions
Warning! Before using the Inverter, read the safety instructions.
Do not expose the inverter to rain, snow, spray or dust. To reduce the risk of
fire hazard, do not cover or obstruct the ventilation openings and do not
install the inverter in a zero-clearance compartment.
To avoid the risk of fire and electric shock, make sure that the existing wiring
is in good electrical condition, and the wire size is not undersized.
This equipment contains components which can produce arcs or sparks. To
prevent fire or explosion do not install in compartments containing batteries
or flammable materials or in locations which require ignition protected
equipment. This includes any space containing gasoline-powered machinery,
fuel tanks, or joints, fittings, or other connection between components of the
fuel system.
Depending on the user scenario, the AC output of the inverter may require
user installed breaker or fuse. In AC output hardwire application, AC socket
will not be provided. The inverter incorporates standard AC short circuit
protection.
The following precautions should be taken when working on the inverter：
Step 1 Remove watches, rings, or other metal objects
Step 2 Use tools with insulated handles
Step 3 Wear rubber gloves and boots

1-2. Other Safety Notes
Upon receipt, examine the carton box for damage. Notify the carrier
immediately, before opening, if damage is evident.
Do not operate near water or in excessive humidity.
The DC side connections should be firm and tight.
Grounding：Reliable grounding should be maintained.
Do not drop a metal tool on the battery. The resulting spark or short-circuit
on the battery or on the other electrical part may cause an explosion.
Install the inverter in a well-ventilated area. Do not block the front air vents,
or the rear air exhausts of the unit.
Wiring：Adequate input power must be supplied to the inverter for proper use;
correct wiring sizes must be ensured.
Mount the inverter such that the fan axis is horizontal.
Do not operate the inverter close to combustible gas or open fire.
Do not operate appliances that may feed power back into the inverter.
Temperature：The inverter should be operated in an ambient temperature
range of -25℃to 40 ℃otherwise the output efficiency may be affected. Air
flow to the inverter must not be blocked.
