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.
