1.1. Notes on Safety
(1) Installation
The inverter must not be installed at places with combustibles or in the vicinity of
combustibles; otherwise there may cause fire.
The inverter must not be installed in an environment exposed to flammable gases;
otherwise There may cause explosion.
(2) Wiring
Confirm that the HV indicator lamp is thoroughly extinguished and the positive/negative
busbar voltage is below 36V; otherwise there may be a risk of electric shock.
Confirm that no wiring operation is permitted unless the power supply is thoroughly
disconnected; otherwise there may be an electric shock hazard.
Don’t try to connect the DC terminals (P+/N-) directly with a dynamic braking resistor;
otherwise there may be a fire hazard.
The terminal voltage of the power supply must not exceed the rated voltage; otherwise
there may be inverter damage.
The earth terminal of the inverter must be properly and reliably earthed in compliance
with the applicable national technical specifications; otherwise there may be an electric
shock hazard;
(3) Inspection Prior to Connection to Power Supply
Prior to connection to the power supply, remember to check that proper wiring is provided
for the electrical peripherals, especially electrical circuits related to the safety of air circuit
breakers and fault alarm devices.
Prior to connection to the power supply, remember to close the cover of the inverter;
otherwise there may be an electrical shock or explosion.
The inverter provides control for high-speed operation of electric motors. If you intend to
apply the inverter to a frequency above the rated motor frequency, you must confirm that
the motor and the electrical parts can support high-speed operation.
(4) Notes on Connection to Power Supply and Operation
Prior to a trial operation, check that all parameters are correctly set.
The front cover must not be opened when the power supply is available, for the high
voltage within may cause an electrical shock.
Do not try to operate an inverter with wet hands; otherwise there may be an electrical
shock.
