Safety Precautions
§
Confirmations upon Delivery
•
Never install an Inverter that is damaged or missing components. Doing so can result in injury.
§
Installation
•
Always hold the case when carrying the Inverter. If the Inverter is held by the front cover, the main body of the Inverter
may fall, possibly resulting in injury.
•
Attach the Inverter to a metal or other noncombustible material.
combustible material.
•
Install a cooling fan or other cooling device when installing more than one Inverter in the same enclosure so that the
temperature of the air entering the Inverters is below 45°C. Overheating can result in fires or other accidents.
§
Wiring
•
Always turn OFF the input power supply before wiring terminals. Otherwise, an electric shock or fire can occur.
•
Wiring must be performed by an authorized person qualified in electrical work. Otherwise, an electric shock or fire can
occur.
•
Be sure to ground the ground terminal. (200 V class: Ground to 100 × or less, 400 V class: Ground to 10 × or less)
Otherwise, an electric shock or fire can occur.
•
Always check the operation of any emergency stop circuits after they are wired. Otherwise, there is the possibility of
injury. (Wiring is the responsibility of the user.)
•
Never touch the output terminals directly with your hands or allow the output lines to come into contact with the Inverter
case. Never short the output circuits. Otherwise, electrical shock or grounding can occur.
•
Check to be sure that the voltage of the main AC power supply satisfies the rated voltage of the Inverter. Injury or fire
can occur if the voltage is not correct.
•
Do not perform voltage withstand tests on the Inverter. Otherwise, semiconductor elements and other devices can be
damaged.
•
Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the I/O wiring examples. Otherwise, a
fire can occur.
•
Tighten all terminal screws to the specified tightening torque. Otherwise, a fire may occur.
•
Do not connect AC power to output Terminal T1, T2, and T3 (U, V, and W). The interior parts of the Inverter will be
damaged if voltage is applied to the output terminals.
