Precautions for Safety
Always read the specifications issued by the machine maker, this manual, related
manuals and enclosed documents before starting installation, operation, programming,
maintenance or inspection to ensure correct usage. Thoroughly understand the basics,
safety information and precautions of this numerical controller before using the unit.
This manual ranks the safety precautions into "DANGER", "WARNING" and "CAUTION".
DANGER When there is a great risk that the user could be subject to
fatalities or serious injuries if handling is mistaken.
WARNING When the user could be subject to fatalities or serious injuries if
handling is mistaken.
CAUTION When the user could be subject to injuries or when physical
damage
Note that even if the items is ranked as " CAUTION", incorrect handling could lead to
serious results. Important information is described in all cases, so please observe the items.
DANGER
Not applicable in this manual.
WARNING
1. Items related to prevention of electric shocks
Do not operate the switches with wet hands, as this may lead to electric shocks.
Do not damage, apply excessive stress, place heavy things on or sandwich the
cables, as this may lead to electric shocks.

ii
CAUTION
1. Items related to noise
Always treat the shield cables indicated in this manual with grounding measures
such as cable clamps.
Separate the signal wire from the drive line/power line when wiring.
2. Items related to installation
Install the control unit and operation board on noncombustible material. Installation
directly on or near combustible material may lead to fires.
Always observe the installation direction.
Do not install or operate a control unit or operation board that is damaged or that
have missing parts.
Do not allow conductive foreign matter such as screws or metal chips or combustible
foreign matter such as oil enter the control unit and operation board.
The control unit and operation board are precision devices so do not drop or apply
strong impacts on them.
Do not install the operation board where it may be subject to cutting oil.
3. Items related to connection
Do not apply voltages other than those indicated in this manual on the connector.
Doing so may lead to destruction or damage.
Incorrect connections may damage the devices, so connect the cables to the
specified connectors.
When using an inductive load such as relays, always connect a diode in parallel to
the load as a noise measure.
When using a capacitive load such as a lamp, always connect a protective resistor
serially to the load to suppress rush currents.
Do not connect or disconnect the connection cables between each unit while the
power is ON.
When using an RS-232-C device as a peripheral devices, caution will be required
when connecting and disconnecting the connector.
Always use a double-OFF type AC power supply switch on the device side, and
connect/disconnect the connector with the AC power supply on the device side
OFF.

3.2.2 Operation Box Heat Radiation Countermeasures
Please refer to following method for heat radiation countermeasures method.
<Hypothetical conditions>
(1) Average temperature in cabinet : 55°C
(2) Cabinet peripheral temperature : Ta ≤0°C~45°C
(3) Internal temperature rise value : ∆T = T −Ta (max) = 10°C
<Supplement>
(1) Refer to "3.1 General Specification" for
the heat generated by each unit.
(2) Enclosed cabinet (thin steel plate)

W1 = U ×A ×∆T
U : 6W/m2×°C

A : Effective heat radiation area (m2)
∆T : Internal temperature rise value

(Area where heat can be radiated from
cabinet)
<Caution>
When calculating the effective heat
radiation area, do not include the parts
that contact other objects.
(3) Points of caution for heat radiation
countermeasures when designing
mounting state
∗Consider convection in cabinet
(eliminate heat spots)
∗Collect hot air at suction port in heat
exchanger panel.
(4) Evaluation standards for internal
temperature rise distribution data
∆T (average value) ≤10°C
∆Tmax (maximum value) ≤15°C
R (inconsistency ∆Tmax −∆Tmin) ≤6°C
(Evaluate existence of heat spots)
Refer to "Section 3.1 General Specifications" for the heating value of each unit.
With the operation box, heat could accumulate at the top of the control unit, so install a circulation fan.
Install a circulation fan in the panel when the following conditions are not satisfied.

3.3.2 Shield Clamping of Cables
The shield cable connected to the control unit, servo amplifier and spindle amplifier must be connected
to the grounding plate to stabilize operation while preventing malfunctioning due to noise.
The shield can be connected to the grounding plate with lead wires, with clamp fittings or with the
connector GNP plate. Refer to the following drawings to treat the shield cable.

Press the exposed part against the grounding plate with
the cable clamp fittings.
(2) If the cable is thin, clamp several together in a bunch.
(3) Use adequate force when tightening the cable so that
the wire material is not damaged.
(4) Connect each grounding plate together and ground
them at one point.

3.3.4 Protective Measures against Lightning Surge
Generally, lightning surge infiltrates the control power supply from the power supply line. Then the
internal circuit is damaged by this control power supply, or via this control power supply.
The Mitsubishi NC unit has a surge absorber on the control power supply for the NC control section and
NC control section. However, this measure is not taken through the control panel, as shown in Fig. 1, so
the lightning surface could flow over the signal line and damage the other devices.

Install the surge absorber on the power supply line for the separately prepared power supply units,
etc., as shown in Fig. 2 and Fig. 3.
The following two measures are required as protection against general damage.
