terminals (for models with communications). If reinforced insulation is required, provide additional insulation, such as spacial distance or
material insulation, as defined by IEC 60664 suitable for the maximum operating voltage.
• Consult with your OMRON representative before using the external power supply for the ES1B for any other purpose.
