Planning the I/O Wiring Routes
The following guidelines provide general information on how to wire the I/O connections to
Productivity3000 PAC's. For specific information on wiring a particular I/O module refer to
the module specifications in Chapter 2.
1. If using removable terminal blocks, follow the wire size guidelines in the I/O modules
specifications in Chapter 2.
2. Always use a continuous length of wire. Do not splice wires to attain a needed length.
3. Use the shortest possible wire length.
4. Use wire trays for routing where possible.
5. Avoid running wires near high energy wiring.
6. Avoid running input wiring close to output wiring where possible.
7. To minimize voltage drops when wires must run a long distance , consider using multiple
wires for the return line.
8. Avoid running DC wiring in close proximity to AC wiring where possible.
9. Avoid creating sharp bends in the wires.
10. When using P3-01DC power supplies, install the recommended powerline filter to reduce
power surges and EMI/RFI noise.
