WARNING
zWhile power is on or when the inverter is running, do not open the front cover. You
may get an electric shock.
zDo 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. Also, the inverter’s ability to withstand earthquakes will deteriorate.
zEven 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.
zBefore starting wiring or inspection, check to make sure that the 3-digit LED inverter
monitor is off, wait for at least 10 minutes after the power supply has been switched off,
and check to make sure that there are no residual voltage using a tester or the like.
zThis inverter must be earthed (grounded). Earthing (grounding) must conform to
the requirements of national and local safety regulations and electrical codes.
(NEC section 250, IEC 536 class 1 and other applicable standards)
zAny person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
zAlways install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
zPerform setting dial and key operations with dry hands to prevent an electric shock.
You may get an electric shock.
zDo not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise you may get an electric shock.
zDo not change the cooling fan while power is on. It is dangerous to change the
cooling fan while power is on.
