2. Fire Prevention
Install the inverter on an incombustible wall without holes, etc. Installing the inverter
directly on or near a combustible surface could lead to 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.
3. Injury Prevention
Apply only the voltage specified in the instruction manual to each terminal to
prevent damage, etc.
Always connect to the correct terminal to prevent damage, etc.
Always make sure that polarity is correct to prevent damage, etc.
While power is on or for some time after power-off, do not touch the inverter as it is
hot and you may get burnt.
4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock,
etc.
(1) Transportation and installation
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the instruction manual.
Do not install or operate if the inverter is damaged or has parts missing.
When carrying the inverter, do not hold it by the front cover or setting dial; it may
fall off or fail.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent other conductive bodies as screws and metal fragments or other
flammable substance as oil from entering the inverter.
As the inverter is a precision instrument, do not drop or subject it to impact.
Use the inverter under the following environmental conditions: This could cause
the inverter damage.
