PRECAUTIONS
To prevent personal injuries or accidents, be sure to
observe the following items.
It is divided into " DANGER" and " CAUTION" according to the risk degree in
this Installation Manual.
DANGER Indicates an imminent hazardous situation where incorrect operation
will result in serious personnel injury or death.
CAUTION Indicates a potentially hazardous situation where incorrect operation
will result in personnel injury or property damage.
CAUTION
• Install the inverter on non-flammable materials such as metal etc. Failure to do so
may lead to fire.
• Do not place the inverter neaar flammable materials. Failure to do so may lead to
fire.
• Do not hold the inverter by terminal cover while transporting it. Failure to do so may
result in personnel injury by its dropping.
• Do not let foreign matters such as metal sheet enter the inverter. Failure to do so
may lead to fire.
• Install the inverter on a place strong enough to support its weight according to the
Instruction Manual. Failure to do so may result in personnel injury by its dropping.
• Do not install or operate an inverter that is damaged or with part(s) missing. Failure
to do so may result in personnel injury.
• Do not connect an AC power supply to output terminals (U, V, W). Failure to do so
may result in personnel injury or fire.
• Make sure that the rated voltage of inverter matches with voltage of AC power
supply.Failure to do so may result in personnel injury or fire.
• Tighten terminal screws to the specified tightening torque. Failure to do so may
lead to fire.
• Do not connect resistor to DC terminals of P/DB+ and N-. Failure to do so may lead
to fire.
• The heat sinks and braking resistors are at high temperature, so do not touch them.
Otherwise it may result in burns.
• The inverter can easily be switched to high speed from low speed, so confirm the
allowable range of the motor and machine before making settings. Failure to do so
may result in personnel injury.
• Set separate holding brakes if required. Failure to do so may result in personnel
injury.
• Employ an electrical engineering company to periodically tighten terminal screws.
Loosen screws may lead to overheating even fire.
