Pre-Installation Planning - Electrical Considerations

Controller rack connected via two Ethernet Hubs to I/O expansion racks (C50 CPU only)

Length of Ethernet cable, each segment: 328 feet (100 meters).

Note: The use of Ethernet cables in excess of 100 meters and/or devices other than approved Hubs

(2 Maximum) will cause transmission delays that could have adverse affects on Controller performance.

It is advantageous to minimize length of I/O wiring. However, it is also a good idea to locate racks (and wiring) away from adverse environmental conditions such as sources of RFI, EMI, and away from areas with high levels of moisture, dust, and corrosive materials.

Electrical Considerations

The HC900 Controller should be mounted in an appropriate metal enclosure. A diagram that shows recommended wiring practice for the cabinet enclosure is given in Figure 20 - Cabinet Wiring, Single Chassis, and Figure 21 - Cabinet Wiring, Multiple Chassis.

Deviations from the installation conditions specified in this manual may invalidate this product's conformity with Low Voltage and EMC Directives.

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.
