SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
z While power is on or when the inverter is running, do not open the front door. You may get an electric
shock.
z Do not run the inverter with the front door opened. Contact with the exposed high-voltage terminals or
charging part of circuitry will cause an electric shock.
z If power is off, do not open the front door except for wiring or periodic inspection. You may access the
charged inverter circuits and get an electric shock.
z Before starting wiring or inspection, switch power off, wait for more at least 10 minutes and check for the
presence of any residual voltage with meter (see chapter 2 for-further details.) etc.
z Any person who is involved in the wiring or inspection of this equipment should be fully competent to do
the work.
z Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured.
z Operate the switches with dry hands to prevent an electric shock.
z Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise, you may
get an electric shock.
2. Fire Prevention
CAUTION
z Install the inverter on an incombustible cubicle. Installing the inverter directly on or near a combustible
surface could lead to a fire.
z If the inverter has become faulty, switch off the inverter power. A continuous flow of large current could
cause a fire.
z Do not connect the resistor directly to the DC terminals +(P), -(N). This could cause a fire.
3. Injury Prevention
CAUTION
z Apply only the voltage specified in the instruction manual to each terminal to prevent damage, etc.
z Ensure that the cables are connected to the correct terminals. Otherwise, damage, etc. may occur.
z Always make sure that polarity is correct to prevent damage, etc.
z After the inverter has been operating for a relatively long period of time, do not touch the inverter as it
may be hot and you may get burnt.
