The cus- tomer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards. Note Applicable EMC (Electromagnetic Compatibility) standards are as follows: EMS (Electromagnetic Susceptibility): EN61131-2 EMI (Electromagnetic Interference): EN61000-6-4 (Radiated emission: 10-m regulations) Low Voltage Directive Always ensure that devices operating at voltages of 50 to 1,000 VAC or 75 to 1,500 VDC meet the required safety standards for the PC (EN61131-2). 6-3 Conformance to EC Directives All CPM1A CPU Units with model numbers ending in “-V1” conform to EC direc-
