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.
Even 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, 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.
This inverter must be earthed (grounded). Earthing (grounding) must conform to
the requirements of national and local safety regulations and electrical codes. (JIS,
NEC section 250, IEC 536 class 1 and other applicable standards)
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.
Perform setting dial and key operations with dry hands to prevent an electric
shock. You may get 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 while power is on. It is dangerous to change the
cooling fan while power is on.
When you have removed the front cover, do not touch the connector above the 3-
digit monitor LED display. Otherwise, you get an electrick shock.
