(IBN) environment. Either of these environments may use a 1/0 AWG ground collector.

The following sections offer guidelines for each of these environments, with and without ground collectors. See local electrical codes or the appropriate IBDN standards for more information.

CBN Grounding Environment

In most facilities using the CBN environment, the bay containing the BitStorm 1900 shelf should be grounded to a frame ground bar (FGB) as the common ground point using a 6 AWG, stranded, ground conductor. In smaller facilities where no FGB exists, the building principal ground (BPG) must be used.

If the facility has a ground collector, the bay must be grounded to the connector using a 6 AWG (stranded) ground conductor to the collector. The collector must then be grounded to the common ground point (FGB or BPG) using a 2 AWG (stranded) ground conductor.

If the distance from the FGB, BPG or ground collector is greater than 53 ft (16 m), a 2 AWG (stranded) ground conductor must be used to ground the bay.

IBN Grounding Environment

In most facilities using the IBN environment, the bay containing the BitStorm 1900 shelf should be grounded using a 6 AWG, stranded, ground conductor to the building single-point ground (SPG) as the common ground point. In smaller facilities where no SPG exists, the building principal ground (BPG) must be used.

If the facility has a ground collector, the bay must be grounded to the connector using a 6 AWG (stranded) ground conductor to the collector. The collector must then be grounded to the common ground point (SPG or BPG) using a 2 AWG (stranded) ground conductor.

If the distance from the SPG, BPG or ground collector is greater than 53 ft (16 m), a 2 AWG (stranded) ground conductor must be used to ground the bay.
