Instruction ManuaI

Thank you for choosing this Mitsubishi Inverter.
This manual gives handling, safety and operating instructions.
Th is section is specifica Ily about safety matters
Read this manual carefully and become familiar with the
inverterbefore operation, pay special attention to the safety
information marked Warning.
This warning symbol indicates the presence of
LtWARNING
dangerous voltage. It informs you of high
HIGH VOLTAG voltage conditions,
situations and locations
that may cause death or serious injury if you
do
not follow precautions.
&WARNING
This symbol indicates ageneral warning.
Serious injury may occur if precautions are not
followed.
Where these Wamings
are written,
pay special attention to the
precautions detailed.

Operator Safety
1. Electric shock prevention
it WARNING HIGH VOLTAGE
&. Do not remove th,e front cover while there is power supplied to
the inverter, there are high voltage terminals which can be
accessed. Please check
the wiring when the inverter is not
powered.
&. There are high voltage capacitors in the main circuit which
remain
charged after the inverter has been turned off, wait 10
minutes after the Power Lamp has gone out and check for no
residual voltage
actoss terminals "P!+" and <:: ("P" and
"N") before touching wires.
&. Use good earthing. Earth the inverter before wiring the Power
circuits and control circuits.
&. Do not operate with wet hands.
&. Do not damage, cut, trap, or degrade the cables.

2. Fire Prevention it. WARNING
6Do not mount on or near combustible material (such as wood)
6Use a circuit breaker on the supply side of the inverter to
prevent high current flow in the case of afault.
6Do not connect a resistor directly to terminals "P" and "N".
3. I njury Prevention it. WARNING
6 Only supply the inverter with the voltage on the nameplate and
in the Manual Specification section.
6 Other voltages may cause the inverter to fail.
6 Care should be taken when wiring to ensure correct terminals
are used. Check polarity etc ...
6Do not touch the inverter while it is powered as certain parts
become hot.

4. Other points
To prevent injury. damage.
or product failure please note the
following points.
(1) Transportation and mounting
~WARNING
& Take care when carrying products. use correct lifting gear.
&Do not stack the inverter boxes higher than the number
recommended.
& Ensure the installation position and material can with stand
the weight of the inverter. Install according to the information
in the I nstruction Manual.
&Do not operate if the inverter is damaged or has parts missing.
&Do not life the inverter with the front cover attached. it may
falloff.
&Do not stand or rest heavy objects on the inverter.
&Check the inverter mounting orientation is correct.
& Prevent any dust. wire fragments or other foreign bodies from
dropping into the inverter during wiring up and commissioning.

LhWARNING
Lt:. Do not drop the inverter. or subject it to impacts.
Lt:. Environmental limitations. Check the ambient temperature.
humidity. storage temperature. atmosphere, altitude. vibration.
-10°C to +50°C (without freezing) -10"C to +40°C for
enclosed specification.
Less than 90% Relative Humidity without condensation.
Ensure the environment is -20°C to +65°C (short time storage
temperature). no corrosive or flammable gasses, altitude less
than 1000m above sea level, vibration is less than 5.9m/s 2 {0.6

(2) Wiring LhWARNING
Lt:. Do not fit power factor correction capacitor. or RFI filter to
the output of the inverter.
Lt:. The connection orientation of the output cables U. V. W to the
motor will effect the direction of rotation of the motor.
A-5

(3) Trial run LhWARNING
.& Check all parameters. and ensure that the machine will not be
dameged by sudden start-up.
(4) Operation LhWARNING
.& When retry function is selected the inverter will try to restart
the machine up to 10 times over a 1 hour period. Ensure
operator safety with other devices.
.& The stop key can only be used at all times to stop the inverter
when a
parameter has been set. therefore use an external
emergency stop button. Switch off start signal when resetting
the inverter. failure to do so may start the motor immediately
after reset.
.& The Electronic motor thermal protection does not guarantee
to prevent motor burn out.
A-6

LhWARNING
.6'; Do not use a contactor in the inverter input for frequent start
/stopping of the inverter. use control signals .
.6'; To reduce the effect of mains conducted electromagnetic
interference use a RFI noise filter.
.6'; Take care to ensure electromagnetic radiation from the
inverter does not damage or effect the operation of nearby
electrical equipment.
.6'; Use an input line reactor when the power supply capacity is
large.
or where harmonics from the inverter will cause
problems .
.6'; Take countermeasures to prevent motor insulation damage
from micro surge voltages in the supply cable.
.6'; Reset the inverter before starting set-up. initialises the
parameters to factory set values.
.6'; Do not use the inverter and motor at high speed until the
machine has been checked.
.6'; The inverter does not have a holding stop facility. For
emergency stop another circuit must be used.
A-7

(5) Emergency stop
~WARNING
.&. Use a circuit and mechanical brake etc. which will protect the
operator of the machine should the inverter fail.
(6) Maintenance and inspection
~WARNING
.&. Do not carry out a megga (insulation resistance) test on the
control circuit of the inverter.
(7) Disposing of the inverter.
~WARNING
.&. Treat as industrial waste.
