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). |

2 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 DO6RE:
1 Internal electronics
2 24 Vdc I/O power segment integrated into the bus bases
3 External isolated power supply 24 Vdc
4 External fuse type T slow-blow 2 A 250 Vac
5 Inductive load protection
6 2-wire load
7 External power supply 100...240 Vac
NOTE: The assigned fuse values have been specified for the maximum current characteristics of the controller or expansion I/O and associated commons. You may have other considerations that are applicable based on the unique types of input and output devices you connect, or conformance to local, national or applicable certification regulations and standards, and you should size your fuses accordingly.
NOTE: Connect the 0 Vdc power circuits together and to the functional ground (FE) of your system to meet the EMC requirements.

|
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OVERHEATING AND FIRE |
|
oDo not connect the modules directly to line voltage. oUse only isolating PELV systems according to IEC 61140 to supply power to the modules. oConnect the 0 Vdc of the external power supplies to FE (Functional Earth/ground). |

UNINTENDED EQUIPMENT OPERATION |
|
Do not connect wires to unused terminals and/or terminals indicated as “No Connection (N.C.)”. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |
