4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric
shock, etc.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter until you
have read through this 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 (basic), the safety
instruction levels are classified into "WARNING" and "CAUTION".
Assumes that incorrect handling may cause hazardous
conditions, resulting in death or severe injury.
Assumes that incorrect handling may cause
hazardous conditions, resulting in medium or
slight injury, or may cause physical damage only.
Note that even the
level may lead to a serious consequence
according to conditions. Please follow the instructions of both levels
because they are important to personnel safety.
1. 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.m
•
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 access the charged inverter circuits and get an electric shock.
•
Before starting wiring or inspection, 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
grounded.
G
rounding must conform to the requirements
of national and local safety regulations and electrical codes. (JIS, 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 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 with wet hands. You may get an electric shock.
2. Fire Prevention
•
Mount the inverter to incombustible material. 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.
•
Do not connect a resistor directly to the DC terminals P/
+
, N/
−
. This could cause a fire.
3. 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 it is hot and you may get burnt.
(1) Transportation and installation
•
When carrying products, use correct lifting gear to prevent injury.
•
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.
*Temperature applicable for a short time, e.g. in transit.

(2) Wiring
•
Do not install a power factor correction capacitor or surge suppressor on the
inverter output side.
•
The connection orientation of the output cables U, V, W to the motor will affect
the direction of rotation of the motor.
(3) Test operation and adjustment
•
Before starting operation, confirm and adjust the parameters. A failure to do
so may cause some machines to make unexpected motions.
(4) Operation
•
When you have chosen the retry function, stay away from the equipment as it
will restart suddenly after an alarm stop.
•
The
key is valid only when the appropriate function setting has been
made. Prepare an emergency stop switch separately.
•
Make sure that the start signal is off before resetting the inverter alarm. A
failure to do so may restart the motor suddenly.
•
The load used should be a three-phase induction motor only. Connection of any
other electrical equipment to the inverter output may damage the equipment.
•
Do not modify the equipment.
•
Do not perform parts removal which is not instructed in this manual. Doing so
may lead to fault or damage of the inverter.
•
The electronic thermal relay function does not guarantee protection of the
motor from overheating.
•
Do not use a magnetic contactor on the inverter input for frequent starting/
stopping of the inverter.
•
Use a noise filter to reduce the effect of electromagnetic interference.
Otherwise nearby electronic equipment may be affected.
•
Take measures to suppress harmonics. Otherwise power supply harmonics
from the inverter may heat/damage the power factor correction capacitor and
generator.
•
When a 400V class motor is inverter-driven, please use an insulation-
enhanced motor or measures taken to suppress surge voltages. Surge
voltages attributable to the wiring constants may occur at the motor terminals,
deteriorating the insulation of the motor.
•
When parameter clear or all clear is performed, reset the required
parameters before starting operations. Each parameter returns to the initial
value.
•
The inverter can be easily set for high-speed operation. Before changing its
setting, fully examine the performances of the motor and machine.
•
In addition to the inverter's holding function, install a holding device to ensure
safety.
•
Before running an inverter which had been stored for a long period, always
perform inspection and test operation.
•
For prevention of damage due to static electricity, touch nearby metal before
touching this product to eliminate static electricity from your body.
(5) Emergency stop
•
Provide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
•
When the breaker on the inverter input side trips, check for the wiring fault
(short circuit), damage to internal parts of the inverter, etc. Identify the cause
of the trip, then remove the cause and power on the breaker.
•
When the protective function is activated, take the corresponding corrective
action, then reset the inverter, and resume operation.
(6) Maintenance, inspection and parts replacement
•
Do not carry out a megger (insulation resistance) test on the control circuit of
the inverter.
(7) Disposing of the inverter
•
Treat as industrial waste.
General instructions
