SK-NIC Wiring Options
5.3.2 SK-NIC Installation
The SK-NIC is designed to mount on one of the SLC expander standoff sets inside the cabinet or remotely using the accessory cabinet.
Use the following steps to mount the SK-NIC inside the 6820.
1. Place the SK-NIC on one of the SLC expander standoff sets.
2. Use the 6-pin cable included with SK-NIC to connect the 6820 to the SK-NIC. Connect the SK-NIC to the pin connector on the control
panel labeled Data Network.
3. Each SK-NIC has the ability to monitor for earth ground faults on the twisted pairs connected to Port 1 of its terminal block TB2. Earth
fault detection for any wiring at Port 2 of TB2 is done at the next/previous -NIC due to these wiring connections being connected to Port
1 of TB2 at the next/previous SK-NIC.
4. Unused optic ports on fiber loop modules must have their dust caps placed on the port.
5. Based on the type of data medium chosen, run the twisted pair wiring/fiber optic cable to the next SK-NIC using a class B or class A
wiring method. A combination of both medium types can be used. See Figure 5.7, Figure 5.8, Figure 5.9, and Figure 5.10 for SK-NIC
wiring examples.
5.3.3 SK-NIC Remote Mounting
Follow the steps above except, the 6-pin cable that runs from the SK-NIC to the 6820 must be run in conduit. Refer to Figure 5.1.
