Thank you for choosing this Mitsubishi Inverter.
1. Electric Shock Prevention
2. Fire Prevention
3. Injury Prevention
4. Additional Instructions
Also the following points must be noted to prevent an accidental failure, injury,
electric shock, etc.
This Instruction Manual provides instructions for advanced use of the FR-A700 series inverters.
Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction Manual and the Instruction Manual
(basic) [IB-0600225ENG] packed with the product carefully to use the equipment to its optimum.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter
until you have read through Instruction Manual (Basic) and
appended documents carefully and can use the equipment
correctly. Do not use the inverter until you have a full knowledge
of the equipment, safety information and instructions. In this
Instruction Manual, the safety instruction levels are classified into
"WARNING" and "CAUTION".
Incorrect handling may cause hazardous
conditions, resulting in death or severe
injury.
Incorrect handling may cause hazardous
conditions, resulting in medium or slight
injury, or may cause only material damage.
The level may even lead to a serious consequence
according to conditions. Both instruction levels must be followed
because these are important to personal safety.
• 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 high-voltage 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 accidentally touch the
charged inverter circuits and get an electric shock.
• Before wiring, inspection or switching EMC filter ON/OFF
connector, power must be switched OFF. To confirm that, LED
indication of the operation panel must be checked. (It must be
OFF.) Any person who is involved in wiring, inspection or
switching EMC filter ON/OFF connector shall 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).
A neutral-point earthed (grounded) power supply for 400V
class inverter in compliance with EN standard must be used.
• Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
• The inverter must be installed before wiring. Otherwise you
may get an electric shock or be injured.
• Setting dial and key operations must be performed 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 replace the cooling fan while power is on. It is
dangerous to replace the cooling fan while power is on.
• Do not touch the printed circuit board or handle the cables with
wet hands. Otherwise you may get an electric shock.
• When measuring the main circuit capacitor capacity (Pr. 259
Main circuit capacitor life measuring = "1"), 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.
WARNING
CAUTION
CAUTION
WARNING
• Inverter must be installed on a nonflammable wall without
holes (so that nobody touches the inverter heatsink on the rear
side, etc.). Mounting it to or near flammable material can cause
a fire.
• If the inverter has become faulty, the inverter power must be
switched OFF. A continuous flow of large current could cause a
fire.
• When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage of
the brake transistor and possibly cause a fire.
• Do not connect a resistor directly to the DC terminals P/+ and
N/-. Doing so could cause a fire.
• The voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst, damage,
etc. may occur.
• The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
• Polarity must be correct. Otherwise burst, damage, etc. may
occur.
• While power is ON or for some time after power-OFF, do not
touch the inverter since the inverter will be extremely hot.
Doing so can cause burns.
(1) Transportation and installation
• The product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to injuries.
• Do not stack the boxes containing inverters higher than the
number recommended.
• The product must be installed to the position where withstands
the weight of the product according to the information in the
Instruction Manual.
• Do not install or operate the inverter if it is damaged or has
parts missing. This can result in breakdowns.
• 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.
• The inverter mounting orientation must be correct.
• Foreign conductive objects must be prevented from entering
the inverter. That includes screws and metal fragments or
other flammable substance such as oil.
• As the inverter is a precision instrument, do not drop or subject
it to impact.
• The inverter must be used under the following environment:
Otherwise the inverter may be damaged.
