Safety information
▶ Read and follow all safety instructions in this guide to understand the safe operating
conditions for the equipment and to avoid property damage and personal injury.
▶ For your safety, Warning and Caution information is provided below.
Warning
Caution
Indicates an imminently hazardous situation which, if not
avoided, may result in severe injury or death.
Indicates a potentially hazardous situation which, if not
avoided, may result in injury or damage to property.
 Do not open the inverter covers while it is energized or operating.
Doing so may cause the inverter to malfunction or result in electric shock.
Do not allow objects, such as metal filings or other debris inside the inverter.
Doing so may cause the inverter to malfunction or result in a fire.
Warning
 Ensure that cables are correctly specified for the inverter’s rated voltage, cable entry,
and terminal arrangement. Ensure that all wiring connections are installed correctly.
Incorrect cable specifications and connections may cause the inverter to malfunction or result
in a fire.
 Apply the correctly rated torque when tightening terminal screws.
Loose screws or over tightened screws may result in an electric shock or a fire.
 Do not install the inverter near flammable objects.
Doing so may cause a fire.
 Ensure that the inverter location or installation method is not affected by vibration.
Vibration may affect the inverter’s operation and result in an electric shock or fire.
 Ensure that the inverter is not serviced or repaired by unauthorized persons.
Unauthorized work may result in an electric shock or a fire and void the warranty.
 Ensure the inverter load does not exceed the product’s rated load and that the inverter is
installed in accordance with the environmental conditions specified in the User’s
Manual.
Exceeding the rated load or incorrectly installing the inverter may cause the inverter to
malfunction, overheat, or result in an electric shock or a fire.
