FIRE HAZARD |
|
oUse only the correct wire sizes for the current capacity of the I/O channels and power supplies. oFor relay output (2 A) wiring, use conductors of at least 0.5 mm2 (AWG 20) with a temperature rating of at least 80 °C (176 °F). oFor common conductors of relay output wiring (4 A), or relay output wiring greater than 2 A, use conductors of at least 1.0 mm2 (AWG 16) with a temperature rating of at least 80 °C (176 °F). |

UNINTENDED EQUIPMENT OPERATION |
|
oUse shielded cables for all fast I/O, analog I/O, and communication signals. oGround cable shields for all fast I/O, analog I/O, and communication signals at a single point1. oRoute communications and I/O cables separately from power cables. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
1Multipoint grounding is permissible if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.
For more information, refer to the TM2...N System Wiring Rules and Recommendation.
If you have physically wired the analog channel for a voltage signal and you configure the channel for a current signal in EcoStruxure Machine Expert, you may damage the analog circuit.
