3. Crimp an RJ45 connector to each cable end. To ensure reliability do not untwist the pairs any
more than necessary to complete the crimp connection. Use care to ensure that the cable
drain wire is securely connected to the shield of the RJ45 connector when the cable is
crimped. Reference the manufacturer’s instructions.
4.10. Electrical Considerations
All racks should be mounted in an appropriate metal enclosure. A diagram that shows recommended
wiring practice for the cabinet enclosure is given in Figure 33 – Cabinet Wiring, Single Chassis, and
Figure 34 – Cabinet Wiring, Multiple Chassis. When Redundant power supplies are used in Redundant
controller racks or I/O racks, separate line power sources are recommended to provide the highest level of
redundancy and system operation.
Deviations from the installation conditions specified in this manual may invalidate this product’s
conformity with Low Voltage and EMC.
Hazardous voltages exist in the equipment enclosure.
Identify and avoid contact with voltage sources.
Failure to comply with these instructions could result in death or serious injury.
Controller Grounding
PROTECTIVE BONDING (grounding) of this controller and the enclosure in which it is installed shall
be in accordance with National Electrical Code (ANSI/NFPA 70) and with local electrical codes.
