Introduction For CE Compliance, the shield of an I/O Link Interface cable must be grounded to the card file’s metal chassis. FASTON terminals are used to provide the connection. 51195479-xxx I/O Link Interface cables The 51195479-xxx I/O Link Interface cables are used in both CE and Non-CE Compliant subsystems. This cable does not have a shield grounding lead or terminal. The shield is grounded through a grounding lead that is attached to the I/O Link protector module on the power cable. The end of the grounding lead has a FASTON terminal which must be connected to the appropriate FASTON terminal on the card file’s metal chassis. 51204042-xxx I/O Link Interface cables Prior to the introduction of the I/O Link protection feature, the CE Compliant subsystems used the 51204042-xxx I/O Link Interface cables. This cable can be identified by its shield wires with FASTON terminals. Upgrading If a system without I/O Link protector modules is being modified and the feature is desired, all power cables must be upgraded by adding a pair of CE Compliant I/O Link protector module adapter cables to each set of power cables. The 51204042-xxx adapter cables are a set of cables that are labeled Link A and Link B. The set of I/O Link Interface cables must then be replaced with a set 5195479-xxx I/O Link cables . DO NOT use the 51204042-xxx I/O Link Interface cables with the I/O Link protector modules. Parts list Table 7-10 lists the part numbers of I/O Link Interface cable sets. Two cables are provided when ordered by the part number.
