1. Safety Instructions
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 compartment
containing batteries or flammable materials or in location 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 been provided. The inverter
incorporates standard AC short circuit protection.
An over current protection at the time of installation shall be
provided by others for the AC output circuit.
Additional breakers suitable for 20A(SE200 & SE350) /
10A(SE400) branch circuit protection shall be provided for the
GFCI receptacles.
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

EN
1-2. Other Safety Notes
Upon receipt, examine the carton box for damage. If you have
found any damage on the carton box please notify the company
you purchased this unit from.
Do not operate near water or in excessive humidity.
Do not open or disassemble the inverter, and warranty may be
voided.
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 air
vents at the front AC output side, or the air exhausts at the rear
DC input side.
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.
The inverter should be operated in an ambient temperature
range：-20℃to 60℃.
Otherwise the output efficiency may be affected. Air flow to the
inverter must not be blocked.

The DC cables should be as short as possible (less than 6 feet / 1.8
meters ideally)
The size of the cable should be thick enough to limit the voltage
drop to less than 2% when carrying the maximum input current to
prevent frequent low-input voltage warnings, and shutdown.
The following sizes of cables and fuses are recommended distance
(<6 ft.) between the batteries and the inverter.
