Caution
Do not install in close vicinity of inflammable substance.
It becomes a cause of fire if installed onto or attached close to combustible material.
Cut off the inverter input (solar cell) and output (AC system) power in the event of
inverter breakdown.
If it is not cut off, fire can breakout due to secondary accident.
Do not touch inverter for several minutes while the power is connected or cut off.
It becomes a cause of burn if it comes in contact with human body since it is very hot.
Do not input power into inverter with damaged product and components even if
installation is completed.
It becomes a cause of electrocution.
Make sure foreign matters including screw, metallic substance, water and oil do not
enter inverter.
It becomes a cause of fire.
Precautions in use
(1) Transportation
Transfer in proper method in accordance with the weight of the product.
Check for any abnormalities in the outer appearance of the product.
Do not pile up in multiple layers in excess of the stipulated regulation.
Do not open the front cover during product transportation
Do not drop or impart strong impact to the inverter since it is a precision device.
(2) Application method
If the automatic operation functions is set at basic value, it operates automatically if the operating
voltage is exceeded and stops automatically if the voltage falls below the operating voltage.
It can be started and stopped with Operation/Stop key on the keypad.
Since the inverter will be reinitiated after prescribed standard by time if the breakdown contents
are reset, manipulate the breakdown reset switch after having assessed the cause.
Do not remodel the internal aspects of the product.
In the case of initializing the parameter, set the parameter necessary prior to operation again. If
the parameter is initialized, the parameter values will be changed to those set at the time of
shipment from factory.
(3) Measures to prevent occurrence of abnormality
If the inverter becomes destroyed and uncontrollable, there are cases in which the mechanical
device is left unattended in hazardous situation. In order to prevent such situation, install additional
safety device such as circuit breaker, etc.
(4) Repair inspection and component replacement
Do not conduct meg-test (measurement of insulation resistance) for the control circuit of inverter.
Refer to Chapter 6 for inspection.
(5) Discard
Discard as ordinary industrial waste.
