D700 QUICK START MANUAL

1. INTRODUCTION

This Quick Start Manual provides instructions for advanced use of
the FR-D700 series inverters. Incorrect handling might cause an
unexpected fault. Before using the inverter, always read this Manual
carefully to use the equipment to its optimum performance. Please
forward this Manual to the end user.

NOTE: Many of the diagrams and drawings in this Manual show the
inverter without a cover, or partially open. Never operate the inverter
in this manner. Always replace the cover and follow this Manual when
operating the inverter.

1.1 SAFETY

Do not attempt to install, operate, maintain or inspect the inverter until
you have read through the Quick Start Manual carefully and can use
the equipment correctly. Do not use this product until you have a full
knowledge of the equipment, safety information and instructions. In
this Installation Guideline, the safety instruction levels are classified
into “

DANGER

” and “

CAUTION”

DANGER

Indicates that incorrect handling may cause

hazardous conditions, resulting in death or severe injury.

CAUTION

Indicates that incorrect handling may cause

hazardous conditions, resulting in medium or slight personal injury
or physical damage.

Depending on the circumstances, procedures indicated by

CAUTION

may also cause severe injury. It is important to follow all precautions for
personal safety.

DANGER

ELECTRIC SHOCK PREVENTION

• While power is on or when the inverter is running, do not open the

front cover. Otherwise you may get an electric shock.

• Do not run the inverter with the front cover or wiring cover removed.

Otherwise, you may access the exposed highvoltage terminals or
the charging part of the circuitry and get an electric shock.

• Even if power is off, do not remove the front cover except for wiring

or periodic inspection. You may access the charged inverter circuits
and get an electric shock.

• Before starting wiring or inspection, switch off power, check to make

sure that the operation panel indicator is off, wait for at least 10
minutes after the power supply has been switched off, and check
that there are no residual voltage using a tester or the like. The
capacitor is charged with high voltage for some time after power off
and it is dangerous.

• This inverter must be earthed (grounded). Earthing (grounding) must

conform to the requirements of national and local safety regulations
and electrical code. (NEC section 250, IEC 536 class 1 and other
applicable standards)

• Any person who is involved in the wiring or inspection of this

equipment should be fully competent to do the work.

• Always install the inverter before wiring. Otherwise, you may get an

electric shock or be injured.

• Perform setting dial and key operations with dry hands to prevent an

electric shock. Otherwise you may get an electric shock.

• Do not subject the cables to scratches, excessive stress, heavy

loads or pinching. Otherwise, you may get an electric shock.

• Do not change the cooling fan while power is on. It is dangerous to

change the cooling fan while power is on.

• Do not touch the printed circuit board with wet hands. Otherwise,

you may get an electric shock.

• When measuring the main circuit capacitor capacity, the DC voltage

is applied to the motor for 1s at powering off. Never touch the motor
terminal, etc. right after powering off to prevent an electric shock.

CAUTION

FIRE PREVENTION

• Install the inverter on a nonflammable wall without holes (so that

nobody can touch the inverter heatsink on the rear side, etc.).
Mounting it to or near combustible material can cause a fire.

• If the inverter has become faulty, switch off the inverter power. A

continuous flow of large current could cause a fire.

• When using a brake resistor, make up a sequence that will turn off

power when an alarm signal is output. Otherwise, the brake resistor
may excessively overheat due to damage of the brake transistor and
such, causing a fire.

• Do not connect a resistor directly to the DC terminals P/+ and N/-.

This could cause a fire.

CAUTION

INJURY PREVENTION

• Apply only the voltage specified in the instruction manual to each

terminal. Otherwise, burst, damage, etc. may occur.

• Ensure that the cables are connected to the correct terminals.

Otherwise, burst, damage, etc. may occur.

• Always make sure that polarity is correct to prevent damage, etc.

Otherwise, burst, damage, etc. may occur.

• While power is on or for some time after power-off, do not touch the

inverter as they will be extremely hot. Doing so can cause burns.

CAUTION

INJURY PREVENTION

• Also note the following points to prevent an accidental failure, injury,

electric shock, etc.

• Transport the product using the correct method that corresponds to

the weight. Failure to observe this could lead to injuries.

• Do not stack the inverter boxes higher than the number

recommended.

• Ensure that installation position and material can withstand the

weight of the inverter. Install according to the information in the
instruction manual.

• Do not install or operate the inverter if it is damaged or has parts

missing.

• When carrying the inverter, do not hold it by the front cover or setting

dial; it may fall off or fail.

• Do not stand or rest heavy objects on the product.
• Check the inverter mounting orientation is correct.
• Prevent other conductive bodies such as screws and metal

fragments or other flammable substance such as oil from entering
the inverter.

• As the inverter is a precision instrument, do not drop or subject it to

impact.

• Use the inverter under the following environmental conditions:

Otherwise, the inverter may be damaged.
