The supply voltage of the FSC system is 24 Vdc, which can be powered from the plant’s 24 Vdc supply system with battery back-up. The FSC system uses an internal 5 Vdc to power the FSC modules. The 10300/1/1 DC/DC converter provides the internal 5 Vdc with galvanic isolation between the two supply voltages.

Note: Keep 10300/1/1 modules off-line for at least 30 seconds after being on-line. 10300/1/1 modules have an NTC resistor as an inrush current limiter. Replacing (or repowering) the module within 30 seconds after removal (or power-off) may cause a supply voltage dip which may trip the system (because the NTC resistor did not yet cool down sufficiently).

Notes:

• • For 10300/1/1 modules without a suffix code, the output LED may remain on in redundant configurations with single I/O, even if the 10300/1/1 is switched off (LED is energized by a redundant 10300/1/1 unit).
• ** 10300/1/1 modules with suffix code 04602 or less are not CE-approved.
