SAFETY INSTRUCTIONS
1. Electric Shock Prevention
WARNING
z
While power is on or when the inverter is running, do not open the front cover. You may get an electric
shock.
z
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.
z
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.
z
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 (check chapter 2 for further details.) etc.
z
Earth the inverter.
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.
z
Do not change the cooling fan while power is on. To do so will invite a hazardous condition.
2. Fire Prevention
CAUTION
z
Mount the inverter on an incombustible surface. 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 a 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.
