Installation and Storage
Do not store or use the product in the following places.
•Locations subject to direct sunlight.
•Locations subject to ambient temperature exceeding the specifications.
•Locations subject to relative humidity exceeding the specifications.
•Locations subject to condensation due to severe temperature fluctuations.
•Locations subject to corrosive or flammable gases.
•Locations subject to exposure to combustibles.
•Locations subject to dust (especially iron dust) or salts.
•Locations subject to exposure to water, oil, or chemicals.
•Locations subject to shock or vibration.
Turn off the power supply and implement wiring correctly. Not doing so may result in a serious injury
due to an electric shock.
Wiring work must be carried out only by qualified personnel. Not doing so may result in a serious
injury due to an electric shock.
Be sure to ground the unit. Not doing so may result in a serious injury due to an electric shock or fire.
(200-V class: type-D grounding, 400-V class: type-C grounding)
Do not connect resistors to the terminals (PD+1, P/+, N/-) directly.
Doing so might result in a small-scale fire, heat generation or damage to the unit.
Install a stop motion device to ensure safety. Not doing so might result in a minor injury. (A holding
brake is not a stop motion device designed to ensure safety.)
Be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking
resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result
in a moderate burn due to the heat generated in the braking resistor/regenerative braking unit.
Configure a sequence that enables the Inverter power to turn off when unusual overheating is
detected in the braking resistor/regenerative braking unit.
The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or
other property. Place covers on the openings or take other precautions to make sure that no metal
objects such as cutting bits or lead wire scraps go inside when installing and wiring.
