1. Important Safety Information
1-1. General Safety Precautions
Warning! Before using the Inverter, read the safety
instructions.
zDo not expose the transfer switch 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.
zTo 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.
zThis 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.
zThe following precautions should be taken when working on the
transfer switch:
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
zUpon 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.
zDo not operate near water or in excessive humidity.
zInstall the transfer switch in a well-ventilated area. Do not block
the front air vents, or the rear air exhausts of the unit.
zDo not operate the transfer switch close to combustible gas or
open fire.
