6.4 External Wiring Example
Considerations on wiring external devices
The following shows the wiring considerations.
Installation precautions
• Safety extension modules fulfill the EMC requirements in accordance with the basic specification IEC 61000-6-2 and EN
61131-2 for industrial use.
• Mitsubishi industrial safety devices are designed only for DC power supply applications which have one power supply and
one power supply destination. For example, if the device is used in power supply networks that comply with IEC 61326-3-1
and use one power supply and multiple power supply destinations, additional protective measures have to be taken.
• When installing devices under the environment of overvoltage category
, an external protection element must be used.
Required protection levels based on EN 62305-1 can be achieved by constructing an external protection circuit. The
installed surge protective device (SPD) should meet the requirements according to EN 61643-11.
• The power supply as well as all signals connected have to fulfill the regulations for extra-low voltages with safe separation
(SELV, PELV) in accordance with IEC 60664 and EN 50178 (equipment of electrical power installation with electronic
devices).
• The installation must prevent common mode disturbances according to IEC 61000-4-16 in the frequency range from 0 Hz
to 150 kHz.
• When using the safety extension modules under the severe noise environment, attach a ferrite core to the cable of a safety
extension module and make 3 turns around the ferrite core. (Ferrite core used in our test: E04SR401938 manufactured by
SEIWA ELECTRIC MFG. CO., LTD). The features of the ferrite core E04SR401938.
• A safety extension module should be installed in a control panel with at least IP54 (IEC 60529) enclosure classification.
• To ensure full EMC compatibility, the DIN rail has to be connected to functional earth (FE).
• To meet the requirements of the relevant product standards (IEC 61496-1), the external power supply for the devices
(SELV) must, among other aspects, be able to bridge a momentary power failure lasting 20 ms.
• All safety related parts (cables, connected sensors and actuators, configuration settings, and EDM) must be according to
the relevant safety standards (IEC 62061 or ISO/EN 13849-1). This may mean that safety related signals need to be
redundant or that single channel signals need protected wiring or short-circuit detection by using test pulse outputs and/or
periodical function tests.
• Install a reset button on the outside of a hazardous area so that it cannot be actuated by a person in the area. When
pressing the reset button, the operator must have full visual command of the hazardous area.
