|
Electrical isolation |
See note 1 |
|
1 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 or 60 V. 2 In parallel operation, only 75% of the rated power can be assumed. Please ensure that all parallel operating power supplies are switched on and off simultaneously. |
|
Do not mount a Power Distribution Module (PDM) side-by-side with a Receiver module.
|
|
|
UNINTENDED EQUIPMENT OPERATION |
|
Do not mount a Power Distribution Module (PDM) next to any one of the following modules: oPower Distribution Module (PDM) oTransmitter module TM5SBET1 or TM5SBET7 oReceiver module TM5SBER2 oInterface Power Distribution Module TM5SPS3 (IPDM) oAnalog input module TM5SAI2H or TM5SAI4H oAnalog output module TM5SAO4L or TM5SAO4H |

Isolation between power segment and TM5 power and data buses |
See note 1 |
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.
