Warning_Color.gifWARNING

UNINTENDED EQUIPMENT OPERATION

oUse shielded cables for all fast I/O, analog I/O, and communication signals.

oGround cable shields for all fast I/O, analog I/O, and communication signals at a single point1.

oRoute communications and I/O cables separately from power cables.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

1Multipoint grounding is permissible (and in some cases inevitable) if connections are made to an equipotential ground plane dimensioned to help avoid cable shield damage in the event of power system short-circuit currents.

For more information, refer to the TM5 System Wiring Rules and Recommendation.

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.
