|
Parallel operation |
Yes 2 |

1 The isolation of the electronic module is 500 Vac RMS between the electronics powered by the TM5 bus and those 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 the TM5 power bus and the 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. 2 In parallel operation, only 75% of the rated power can be assumed. Ensure that all parallel operating power supplies are switched on and off simultaneously. |

The TM5SPS3 is subject to temperature restrictions depending on the current consumption on the TM5 power bus:
oup to 500 mA: 0...60°C (32...140°F)
oover 500 mA: 0...55°C (32...131°F)
