Appendix 5 EMC and Low Voltage Directives
Requirements for Low Voltage Directive compliance
Module
The module operates at the rated voltage of 24VDC. The Low Voltage Directive is not applied to the modules that operate at
the rated voltage of less than 50VAC and 75VDC.
External wiring
■
24VDC external power supply
To connect to the module, use the power supply that meets the following conditions:
• SELV (Safety Extra Low Voltage): Product with reinforced insulation from the hazardous potential part (60V or higher)
• LVD applicable product
• 24VDC (ripple ratio: 5% or less) (allowable voltage range: 20.4 to 28.8VDC)
■ External devices
For external devices connected to a module, use the one of which insulation between the interface circuit section to the
module and the dangerous voltage circuit section is reinforced (if the device internally has a dangerous voltage circuit
section).
■
Reinforced insulation
The reinforced insulation covers the withstand voltages shown in the table below.
