Appendix 2 Standards
Caution for compliance with EC Directive
• Please use the FX5UC CPU modules while installed in conductive shielded control panels under a general industrial
environment.
• Programmable controllers are open-type devices that must be installed and used within conductive control panels. Please
secure the control box lid to the control box (for conduction). Installation within a control box greatly affects the safety of the
system and aids in shielding noise from the programmable controller.
• For the control panel, use the product having sufficient strength, fire protectiveness and shielding property to an installation
environment.
• 24 V DC of the power supply must be supplied from the circuit double/reinforced insulated from the main power supply
(MAINS).
[Caution for compliance with the LVD directive (EN61010-2-201:2013)]
*1
• To an external connection port other than AC power supply terminal and AC input/output terminal, connect the circuit
separated from a dangerous voltage by a double/reinforced insulation.
• Between the commons having the adjacent relay output terminals, if an external power supply is higher than 120 V AC, the
insulation is basic. Therefore, when using 120 V AC or higher external power supply and 30 V DC/AC or lower external
power supply between the adjacent commons, do not handle 30 V DC/ AC or lower external power supply as a touchable
part, (When handling 30 V DC/AC or lower external power supply as a touchable part, add a basic insulation.)
• Do not wire two or more crimp terminals to one terminal. (If the wiring with two or more wires is needed, take an appropriate
action such as adding an external terminal.)
• For crimp terminals to be used for the wiring applied with 30 V AC or higher, use the products with insulating sleeves.
• Cutoff device such as a breaker or a circuit protector should be installed in accordance with the following precautions.
- Use EN60947-1 or EN60947-3 standards.
- Place the cutoff device so that it can be operated easily.
- Specify that the cutoff device is for this equipment.
*1 For the time of compliance with the LVD directive (EN61010-2-201:2013), refer to  Page 151 Requirement for Compliance with LVD
directive.

Caution for when analog products are used
It is recommended to perform the following when precision of measuring and control is required.
As analog devices are sensitive by nature, their use should be considered carefully. For users of proprietary cables (dedicated
for sensors or actuators), these users should follow those manufacturers' installation requirements.
Mitsubishi Electric recommends that shielded cables be used. If no other EMC protection is provided, users may experience
temporary loss of accuracy b10%/-10% in very heavy industrial areas.
However, Mitsubishi Electric suggests that if adequate EMC precautions are followed with general good EMC practice for the
user's complete control system, users should expect normal errors as specified in this manual.
• Sensitive analog cables should not be laid in the same trunking or cable conduit as high voltage cabling. Where possible,
users should run analog cables separately.
• Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth loops are accidentally
created.
• When reading analog values, EMC induced errors can be smoothed out by averaging the readings. This can be achieved
either through functions on the analog special adapters/blocks or through a user's program in the FX5UC CPU module.
Perform the following when using the analog expansion adapter:
• Installation in Enclosure
Programmable controllers are open-type devices that must be installed and used within conductive control cabinets.
Please use the programmable controller while installed within a conductive shielded control cabinet. Installation within a
control cabinet greatly affects the safety of the system and aids in shielding noise from the programmable controller.
