This Instruction Manual (Basic) provides handling information and precautions for use of the equipment.
Please forward this Instruction Manual (Basic) to the end user.
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.
(1) Transportation and Mounting
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the
inverter until you have read through the Instruction Manual
(Basic) 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 Instruction Manual (Basic), 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.
z While power is ON or when the inverter is running, do not
open the front cover. Otherwise you may get an electric
shock.
z 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.
z 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.
z 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.
z
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.
z Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
z The inverter must be installed before wiring. Otherwise you
may get an electric shock or be injured.
z Setting dial and key operations must be performed with dry
hands to prevent an electric shock. Otherwise you may get
an electric shock.
z Do not subject the cables to scratches, excessive stress,
heavy loads or pinching. Otherwise you may get an electric
shock.
z Do not change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
z Do not touch the printed circuit board or handle the cables
with wet hands. Otherwise you may get an electric shock.
z 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.
WARNING
CAUTION
CAUTION
WARNING
zInverter 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.
zIf the inverter has become faulty, the inverter power must
be switched OFF. A continuous flow of large current could
cause a fire.
z
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.
zDo not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
zThe voltage applied to each terminal must be the ones
specified in the Instruction Manual. Otherwise burst,
damage, etc. may occur.
zThe cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
zPolarity must be correct. Otherwise burst, damage, etc.
may occur.
zWhile 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.
zThe product must be transported in correct method that
corresponds to the weight. Failure to do so may lead to
injuries.
zDo not stack the boxes containing inverters higher than the
number recommended.
zThe product must be installed to the position where
withstands the weight of the product according to the
information in the Instruction Manual.
zDo not install or operate the inverter if it is damaged or has
parts missing.
zWhen carrying the inverter, do not hold it by the front cover
or setting dial; it may fall off or fail.
zDo not stand or rest heavy objects on the product.
zThe inverter mounting orientation must be correct.
zForeign conductive objects must be prevented from
entering the inverter. That includes screws and metal
fragments or other flammable substance such as oil.
zAs the inverter is a precision instrument, do not drop or
subject it to impact.
zThe inverter must be used under the following
environment: Otherwise the inverter may be damaged.
