10. ON/OFF Control
(+ON/OFF, -ON/OFF terminal)
The CPFE1000FIxx is equipped with a ON/OFF control function.
Without turning the input supply on and off, the
output can be enabled and disabled using this function.
The ON/OFF control circuit is isolated from input circuit of the power supply by a photo-coupler.
The unit comes factory set for local ON/OFF control, via jumpers on the J4 connector. For external control, the J4
jumpers need to be removed.
Fig. 10-1 and Fig. 10-2 are examples of how to connect to the
ON/OFF control. When the external ON/OFF control is
not used, re-install jumpers onto J4 connector (J4-1 & J4-2 shorted, J4-3 & J4-4 shorted).
