Wiring Diagram and Timing Chart

The following figures show the CPS214 wiring diagram (left) and the 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. 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 for capacitor values.

NOTE: See Power and Grounding Considerations for AC and DC Powered

Systems, page 731 for power and grounding wiring guidelines and operational

information.
