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. |
|
|
|
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 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 TM218 System Wiring Rules and Recommendation.

NOTICE |
|
INOPERABLE EQUIPMENT |
|
Verify that the physical wiring of the analog circuit is compatible with the software configuration for the analog channel. |
|
Failure to follow these instructions can result in equipment damage. |
