Wiring Diagram
and Timing Chart
The following figures show the 140CPS22400 wiring diagram (left) and the
140CPS22400 hold-up capacitor timing chart (right).
Note:
1. A normally closed relay contact rated at 220 Vac, 6A / 30 Vdc, 5A is available
on terminals 1 and 2 of the power terminal strip. This contact set may be used
to signal input power OFF, or a power supply failure. The relay will de-energize
when input power drops below 8 Vdc.
2. Tolerance to input interruptions may be increased by adding a 50 Vdc
electrolytic capacitor between 5 and 6 of the power terminal strip. Refer to the
hold-up capacitor timing chart (above) for capacitor values.
Note: See Power and Grounding Considerations for AC and DC Powered
Systems, p. 776 for power and grounding wiring guidelines and operational
information.
