FIRE HAZARD |
|
oUse only the correct wire sizes for the maximum 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 (7 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). |

1 The isolation of the electronic module is 500 Vac RMS between the electronics powered by TM5 power bus and the part powered by 24 Vdc I/O power segment connected to the module. In practice, the TM5 electronic module is installed in the bus base, and there is a bridge between TM5 power bus and 24 Vdc I/O power segment. The two power circuits reference the same functional ground (FE) through specific components designed to reduce effects of electromagnetic interference. These components are rated at 30 Vdc or 60 Vdc. This effectively reduces isolation of the entire system from the 500 Vac RMS.
The following illustration describes the wiring diagram of the DI12DE:

POTENTIAL EXPLOSION OR FIRE |
|
Connect the returns from the devices to the same power source as the 24 Vdc I/O power segment serving the module. |
