Concepts
EMC Directive
The SmartSlice I/O Terminals are electrical devices which are installed in a machine in application.
The Terminals comply with the EMC Directive. This makes it easier for the machine in which a Ter-
minal is installed to more easily comply with the EMC directive. (See note.)
The EMC-related performance of the OMRON devices which comply with EC Directives changes
with the machine in which they are installed. This includes the configuration, connections, and other
conditions of the machine. The customer must do the checks to make sure that the devices and the
machine conform to EMC standards.
Note:
The applicable EMC (electro-magnetic compatibility) standards are EN 61131-2 and EN 61000-6-2
for EMS (electro-magnetic susceptibility) and EN 61131-2 and EN 61000-6-4 for electro-magnetic
interference. The 10-m regulations apply for radiated emissions.
Low Voltage Directive
Devices which operate at voltages from 50 to 1,000 VAC or 75 to 1,500 VDC must comply with the
related safety requirements. The applicable standard is EN 61131-2.
Complying with EC Directives
The SmartSlice I/O Units comply with EC Directives. These measures are necessary for the ma-
chine containing a SmartSlice I/O Units to comply with the EC Directives.
1. You must install the SmartSlice I/O Units in a control panel.
2. You must use reinforced insulation or double insulation for the DC power supplies used for the
Unit power supplies, and the I/O power supplies. Make sure that the outputs are stable if a 10-ms
interruption occurs at the input.
We recommend the S82J Power Supply which is made by OMRON. (See note.)
3. The SmartSlice I/O Units which conform to EC Directives conform to the EMI standards (EN
61131-2 (Immunity Zone A), EN 61000-6-2, and EN 61000-6-4). The radiated emission proper-
ties (10-m regulations) can change with the configuration of the control panel, other devices
which are connected to the control panel, connections, and other conditions.
You must make sure that the completed machine complies with EC Directives.
4. Compliance tests were done with I/O wires of a maximum length of 30 m.
Note:
Compliance tests for EMC standards were done with the recommended power supply.
