In this instruction manual, the safety instruction levels are classified into "WARNING"
and "CAUTION".
WARNING
CAUTION
Note that even the
according to conditions. Please follow the instructions of both levels as they are
important to personnel safety.
1. Electric Shock Prevention
! ! ! ! While power is on or when the inverter is running, do not open the front cover. You
may get an electric shock.
! ! ! ! Do not run the inverter with the front cover removed. Otherwise, you may access
the exposed high-voltage terminals or the charging part of the circuitry and get an
electric shock.
! ! ! ! If power is off, do not remove the front cover except for wiring or periodic inspection.
You may access the charged inverter circuits and get an electric shock.
! ! ! ! Before starting wiring or inspection, switch power off, wait for more than at least 10
minutes and check for the presence of any residual voltage with a meter, etc.
! ! ! ! Earth (ground) the inverter in a class D or higher protective earthing (grounding)
method.
! ! ! ! Any person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
! ! ! ! Always install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
! ! ! ! Operate the switches with dry hands to prevent an electric shock.
! ! ! ! Do not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise, you may get an electric shock.
! ! ! ! Do not change the cooling fan with power on. It is dangerous to change the cooling
fan while power is on.
2. Fire Prevention
! ! ! ! Mount the inverter on incombustible material. Mounting it to or near combustible
material can cause a fire.
! ! ! ! If the inverter has become faulty, switch off the inverter power. A continuous flow of
large current could cause a fire.
! ! ! ! Do not connect a resistor directly to the DC terminals P(+), N(+). This could cause a fire.
