3. Connecting operator interface devices to the module communication
port.
4. Checking the module operation.
The PPX:505-2571 requires 5 watts of +5VDC power. Before inserting the
module into the I/O base, ensure that the power supply capacity is not
exceeded.
RS–232 communications cables should be no longer than 50 feet in length.

CAUTION
The components on the PPX:505-2571 module printed circuit card can be
damaged by static electricity discharge.
To prevent this damage, the module is shipped in a special anti-static bag.
Static control precautions should be followed when removing the module from
the bag, and when handling the printed circuit card during configuration
.
After discharging any static build–up, remove the module from the
anti-static bag. Do not discard the static bag. Always use this bag for
protection against static damage when the module is not inserted into the
I/O base.
