Cabling
This section shows how to cable the device. Intra-building connections of the device
require the use of shielded cables grounded at both ends.
Caution:
The intra-building ports of the equipment are suitable for connection to intra-
building or unexposed wiring or cabling only. The intra-building ports of the equipment
must not be metallically connected to interfaces that connect to the Outside Plant
(OSP) or its wiring. These interfaces are designed for use as intra-building interfaces
only (Type 2 or Type 4 ports, as described in GR-1089–CORE, Issue 4) and requires
isolation from the exposed OSP cabling. The addition of primary protectors is not
sufficient protection to connect these interfaces metallically to OSP wiring.
4.1
Grounding
The device is intended for use in both common bonding networks and isolated bonding
networks. Grounding must comply with local, national, and other applicable government
codes and regulations. Dedicated safety grounds are implemented on both the AC and DC
versions of the product. The AC product uses a standard three wire cord that includes a
safety ground for each power supply. The DC product has a dedicated ground screw on
each power supply.
Warning:
To ensure the safety ground, at least one power supply with an
appropriately terminated ground lead must be installed at all times.
Tip:
To ensure the safety ground, at least one power supply with an appropriately
terminated ground lead must be installed at all times.
