 Wiring Notes
The following guidelines provide general information on how to wire the I/O connections to DVP PLCs.
 Environment
1. DO NOT store the PLC in a dusty, smoky, or corrosive atmosphere.
2. DO NOT store the PLC in an environment with high temperature or high humidity.
3. DO NOT install PLC on a shelf or on an unstable surface.
 Construction
1. Some machine fabrication environments may accidentally cause conductive debris to fall through the DVP cooling
vents and into the unit. ALL DVP units come with a protective sheet wrapped round the unit, covering the cooling
vents. However, it must be removed before electrical operation.
2. There should be a 50mm or more distance between the PLC and other control components. Also, keep the PLC
away from high voltage lines & power equipment.
 Avoid creating sharp bends in the wires.
 Avoid running DC wiring in close proximity to AC wiring.
 To minimize voltage drops on long wire runs, consider using multiple wires for the return line.
 Avoid running input wiring close to output wiring where possible.
 Avoid running wires near high power lines.
 Use wire trays for routing where possible.
 Use the shortest possible wire length.
 Always use a continuous length of wire. Do not splice wires to attain a needed length.
 Recommended wire terminations.
