Field Supply

Observe the following requirements for the field supply:

• For non-hazardous active voltages per EN/UL/IEC 61010-1, use SELV/PELV power supplies.
• Use suitable overcurrent protection for each infeed. You can find detailed product information in the corresponding & Product Manual.

Additional supply modules are needed for:

• Higher power requirements
• Use of different reference voltages
• Use of different field voltages (e.g., 230 VAC, 120 VAC or 24 VDC)
• Switching to special applications and environments (e.g., Ex i)

Adding a supply module interrupts the field power supply that passes through the power jumper contacts. A new power infeed, which may also include a potential change, begins at that point.
