This Installation Guideline provides handling information and precautions for use of the equipment.
Please forward this Installation Guideline to the end user.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the
inverter until you have read through the Installation Guideline
and appended documents 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 "WARNING" and "CAUTION".
Incorrect handling may cause
WARNING
hazardous conditions, resulting in death
or severe injury.
Incorrect handling may cause
CAUTION
hazardous conditions, resulting in
medium or slight injury, or may cause
only material damage.
CAUTION
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.
1. Electric Shock Prevention
WARNING
 While the inverter power is ON, do not remove the front
cover or the wiring cover. Do not run the inverter with the
front cover or the 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 or inspection, 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 or inspection 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 61140 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 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 or handle the cables
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.
2. Fire Prevention
CAUTION
 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.
 Be sure to perform daily and periodic inspections as specified
in the Instruction Manual. If a product is used without any
inspection, a burst, breakage, or a fire may occur.
3.Injury Prevention
CAUTION
 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 as they will be extremely hot. Doing so
can cause burns.
4. Additional Instructions
Also the following points must be noted to prevent an
accidental failure, injury, electric shock, etc.
(1) Transportation and Mounting
CAUTION
 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.
 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.
