C. Two power supplies where one supply is on continuously when AC
Control Power is present (circuits 2 and 3), and the other supply is
on only when Hazardous Power is present in the Main Area (circuit
1). See schematic below.
D. Two power supplies where one supply is on continuously when AC
Control Power is present (circuit 1), and the other supply is on only
when Hazardous Power is present in the Main Area (circuit 2 and
3). See schematic below.

Design Note: Use 14 AWG wire with a temperature rating of 90°C or
greater or 12AWGwhen fabricating AC wiring to any connected 24V
power supply. 12 AWG or larger wire if it has insulation rated at or above
70 degrees C). Note: Your 24VDC supplies should have an internal fuse
or other current limiting device to protect against catastrophic failure of
the supply itself (this is typical of most commercially available drives).
Refer to Appendix C for a typical cable diagram for connecting the
24VDC supply to the eF-785.

(P9-P11)
There are 3 circuits for the distribution of 24VDC power which are rated
up to 10A each, for a total of 30A. Each 24V-distribution circuit includes
two distribution connectors on the rear panel: P9A-P9B, P10A-P10B and
P11A-P11B. Each of these three 24V circuits has its own dedicated front
panel fuse (F8, F9, and F10, respectively.) Each fuse has a dedicated a
blown fuse indicator LED.
