Application
• The EQ7 drive is designed to drive a three-phase induction motor. Do not use it for single-phase
motors or for other purposes.
Fire or an accident could occur.
• The EQ7 drive may not be used for a life-support system or other purposes directly related to the
human safety.
• Though the EQ7 drive is manufactured under strict quality control, install safety devices for
applications where serious accidents or property damages are foreseen in relation to the failure of
it.
An accident could occur.
Installation
• Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• Inverters with a capacity of 50 HP or above, whose protective structure is IP00 (Open Chassis),
involve a possibility that a human body may touch the live conductors of the main circuit terminal
block. Inverters to which an optional DC reactor is connected also involve the same. Install such
inverters in an inaccessible place.
Otherwise, electric shock or injuries could occur.
• Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into
the inverter or from accumulating on the heat sink.
• When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or an accident might result.
• Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.
