Confirmations upon Delivery
CAUTION
Page
D
Never install an Inverter that is damaged or missing components.
Doing so can result in injury.
NO TAG

Installation
CAUTION
Page
D
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 result-
ing in injury.
NO TAG
D
Attach the Inverter to a metal or other noncombustible material.
Fire can result if the Inverter is attached to a combustible material.
NO TAG
D
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
WARNING
Page
D
Always turn OFF the input power supply before wiring terminals.
Otherwise, an electric shock or fire can occur.
NO TAG
D
Wiring must be performed by an authorized person qualified in electrical work.
Otherwise, an electric shock or fire can occur.
NO TAG
D
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.
NO TAG
D
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.)
NO TAG
D
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.
NO TAG
CAUTION
Page
D
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.
NO TAG
D
Do not perform voltage withstand tests on the Inverter.
Otherwise, semiconductor elements and other devices can be damaged.
NO TAG
D
Connect braking resistors, Braking Resistor Units, and Braking Units as shown in the
I/O wiring examples.
Otherwise, a fire can occur.
NO TAG
D
Tighten all terminal screws to the specified tightening torque.
Otherwise, a fire may occur.
NO TAG
D
Do not connect AC power to output terminals U, V, and W.
The interior parts of the Inverter will be damaged if voltage is applied to the output terminals.
