General Precautions
Be sure prior to installation, running, maintenance, and inspection, to thoroughly read this
manual and other affiliated materials, and to use the product properly. Use this product only
after familiarizing onesel f with al l sa fety i n forma tion and c autiona ry i tem s, and havi ng a t horough knowledge of the device.
Safety and cautionary items in this operator’s manual are classified by rank as “Warnings” or
“Cautions”.
WARNING
Mis-operation may result in a hazardous condition leading to death or serious
injury.
CAUTION
Mis-operation may result in a hazardous condition leading to medium or light
injury or physical damage to the device.
In addition, items marked with a “Caution” may lead to serious consequences depending on
the situation. Observe both as the content of either one is important.

Inspection Upon Receipt of this Product
CAUTION
• Do not install or operate a converter which is damaged or has parts missing
from it. This may result in injury.
Installation
WARNING
• Install this unit after verifying that the input power is OFF. Failure to do so
may lead to electric shock or fire.
• Wiring should be performed by a skilled electrician. Failure to do so may lead
to electric shock or fire.
• Be sure to ground the grounding terminal. Failure to do s o may lead to electric
shock or fire.
CAUTION
• Check that the rated voltage of the converter matches the AC source voltage.
Failure to do so may lead to injury or fire.
• Do not perform a withstand voltage test on the converter . This will lead to
damage on the semiconductor elements.
• Connect the input AC reactor, high-frequency filter reactor, and high-frequency filter capacitor exactly as shown in the operator’s manual. Failure to
do so may lead to fire.
• Check that the total load connected to the converter is within the rated output
capacity of the converter. Failure to do so may lead to fire.
• Check that the rated voltage of the converter and the rated voltage of the connected inverter match. Failure to do so may lead to fire.
• Fasten terminal screws securely. Failure to do so may lead to mis-operation,
damage to the device, or fire.

Running
• Be sure to turn input power ON only after installing the front cover and terminal cover. Do not remove the cover while power is applied. Removing any
cover duri ng operation, or operating devi ce with cover removed, may lead to
electric shock.
• Do not operate the digital operator or switches with wet hands. This may lead
to electric shock.
• Do not touch the converter terminals while power is being applied to the converter , even while stopped. This may lead to electric shock.
• Do not touch the cooling fin or input AC reactor as they become hot. This may
lead to burns.
• Do not perform signal checks during operation. This may damage the unit.
• This converter has been properly set at the factory at time of delivery. Do not
carelessly change these settings as it may damage the device.
WARNING
CAUTION
Maintenance/Testing
• Do not touch the terminals on the converter as they carry a high voltage . This
may lead to electric shock.
• Perform maintenance and testing after removing main power and verifying
that the CHARGE lamp has gone out. There is danger in that a char ge remains
in the capacitor. This may lead to electric shock. In any case, use a voltameter
to measure for high voltage prior to performing maintenance.
• Only designated persons should perform maintenance, testing, and parts
replacement. When performing maintenance, remove accessories (watches,
bracelets, etc.) prior to working. Use insulated tools. Failure to do so may lead
to electric shock or injury.
• Do not try to modify the unit. This may lead to electric shock, injury, or damage to the device.
• This converter uses semiconductor elements. Keep this in mind when handling. Damage to the converter may result from static electricity, etc.
• Do not modify the wiring, or install/remove the converter while power is
applied. This may result in electric shock, injury, or damage to the device.
