Specifications Test Item Test Description Standard Values 30M-230 M Hz QP: 30dBμ...
3.1.2 Installation instructions for EMC Directive The programmable controller is open equipment and must be installed within a control cabinet for use.* This not only ensures safety but also ensues effective shielding of programmable controller-generated electromagnetic noise. * : Also, each network remote station needs to be installed inside the control panel.
3.1.3 Cables The cables pulled out of the control panel contain a high frequency noise component. On the outside of the control panel, therefore, they serve as antennas to emit noise. Ensure to use shielded cables for the cables, which are connected to the I/O modules, special modules and those pulled out to outside of the control panel.
(2) MELSECNET (II) and MELSECNET/10 units (a) Use a double-shielded coaxial cable for the MELSECNET unit which uses coaxial cables. Noise in the range of 30 MHz or higher in radiation noise can be suppressed by the use of double-shielded coaxial cables (Mitsubishi Cable: 5C-2V-CCY).
(c) Always use double-shielded coaxial cables as the coaxial cables*2 connected to the 10BASE2 connectors. Earth the double-shielded coaxial cable by connecting its outer shield to the ground. Shield Earth here Refer to (1) for the earthing of the shield. *2: Make sure to install a ferrite core for the cable.
(5) Positioning Modules Precautions to be followed when the machinery conforming to the EMC Directive is configured using the A1SD75P -S3 are described below. (a) When wiring with a 2 m (6.56 ft.) or less cable • Ground the shield section of the external wiring cable with the cable clamp.
(c) Ferrite core and cable clamp types and required quantities • Cable clamp Type : AD75CK (Mitsubishi Electric) • Ferrite core Type : ZCAT3035-1330 (TDK ferrite core) • Required quantity Required Qty Cable length Prepared part 1 axis 2 axes 3 axes Within 2 m (6.56 ft.)
[Simplified diagram] Local module Remote module Master module (Blue) (White) Terminal (Yellow) Terminal resistor resistor CC-Link CC-Link dedicated dedicated cable cable (d) Power line connecting to the external power supply terminal (compliant with I/O power port of CE standard) should be 30m (98.43 ft.) or less. Power line connecting to module power supply terminal (compliant with main power port of CE standard) should be 10m (32.81 ft.) or less.
3.1.5 Ferrite core A ferrite core has the effect of reducing radiated noise in the 30 M Hz to 100 M Hz band. With the exception of some models, it is not required to fit ferrite cores to cables, but it is recommended to fit ferrite cores if shield cables pulled out of the enclosure do not provide sufficient shielding effects.*1 The ferrite cores used in our tests are TDK's ZCAT3035.
3.1.6 Noise filter (power supply line filter) A noise filter is a component which has an effect on conducted noise. With the exception of some models, it is not required to fit the noise filter to the power supply line, but fitting it can further suppress noise. (The noise filter has the effect of reducing conducted noise of 10 M Hz or less.) Use any of the following noise filters (double type filters) or equivalent.
3.2 Requirements for Compliance with Low Voltage Directives The Low Voltage Directives apply to the electrical equipment operating from 50 to 1000VAC or 75 to 1500VDC; the manufacturer must ensure the adequate safety of the equipment. Guidelines for installation and wiring of MELSEC-AnS series programmable controller are provided in Section 3.2.1 to 3.2.7 for the purpose of compliance with the EMC Directives.
3.2.3 Power supply The insulation specification of the power module was designed assuming installation category II. Be sure to use the installation category II power supply to the programmable controller. The installation category indicates the durability level against surge voltage generated by a thunderbolt.
3.2.5 Module installation (1) Installing modules contiguously In Q2AS series programmable controllers, the left side of each I/O module is left open. When installing an I/O module to the base, do not make any open slots between any two modules. If there is an open slot on the left side of a module with 100/200 VAC rating, the printed board which contains the hazardous voltage circuit becomes bare.

(6) Keep the following distance between the programmable controller and other devices (such as a contactor and a relay) in order to avoid the influence of radiated noise and heat: a device installed in front of the programmable controller...
4.2 Fail-Safe Circuit Concept When the programmable controller is powered ON and then OFF, improper outputs may be generated temporarily depending on the delay time and start-up time differences between the programmable controller power supply and the external power supply for the control target (especially, DC). For example, if the external power supply for the control target is powered ON and then the programmable controller is powered ON, the DC output module may generate incorrect outputs temporarily upon the programmable controller...
Create a safety circuit outside the programmable controller to DANGER ensure the whole system will operate safely even if an external power failure or a programmable controller failure occurs. Install the emergency stop switch outside the controlpanel so that workers can operate it easily. Otherwise, incorrect output or malfunction may cause an accident.
When controlling a running programmable controller (data DANGER modification) by connecting a peripheral device to the CPU module or a PC to a special function module, create an interlock circuit on sequence programs so that the whole system functions safely all the time.
