Wiring Diagram
The following figure shows the CPS41400 wiring diagram.
NOTE: 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.
NOTE: See (see page 731) for power and grounding wiring guidelines and
operational information.
Operating Curve and Timing Chart
The following figures show the CPS41400 operating curve (left) and the hold-up
capacitor timing chart (right).
NOTE: Tolerance to input interruptions may be increased by adding a ≥ 80 Vdc
electrolytic capacitor between 5 and 6 of the power terminal strip. Refer to the hold-
up capacitor timing chart (above) for capacitor values.
