The P24/48 external power supply can be powered by 20 to 60 VDC. It must
be a dedicated fused feed. Refer to the following wiring diagram:
Using Custom Cables with I/O Expansion Boards
When using Expansion Board A with a custom connecting cable longer than
the standard 3 feet (0.9m), you cannot use any analog I/O modules unless
you use an external power supply. The power supply options available are
the same as those listed for Expansion Board B.
When using an external power supply with Expansion Board A, you must
remove the jumper (JMPR) on the board (see the diagram on page 2).
Failure to do so will void the 9700 Power Meter warranty.
To install an I/O device, simply plug it in to an appropriate slot and tighten
the fastening screw.
There are several restrictions governing the use of the Expansion I/O
Boards. Read the section below detailing I/O device restrictions before
connecting any devices to the expansion boards. Further details are
provided in the section "I/O Expansion Boards" in the 9700 Power Meter
User's Guide .
