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). |
