HP Integrity Superdome and 9000 Superdome sx2000 manual Grounding, Circuit Breaker, Power Options

Grounding

The site building must provide a safety ground or protective earth for each ac service entrance to all cabinets.

WARNING! This equipment is Class 1 and requires full implementation of the grounding scheme to all equipment connections. Failure to attach to protective earth results in loss of regulatory compliance and creates a possible safety hazard.

Circuit Breaker

Each cabinet using a 3-phase, 4-wire input requires a dedicated circuit breaker to support the Marked Electrical current of 44 A per phase. The facility electrician and local service codes determine proper circuit breaker selection.

Each cabinet using a 3-phase, 5-wire input requires a dedicated circuit breaker to support the Marked Electrical current of 24 A per phase. The facility electrician and local service codes determine proper circuit breaker selection.

NOTE: When using the minimum-size breaker, always choose circuit breakers with the maximum allowed trip delay to avoid nuisance tripping.

Power Options

Table 2-6describes the available power options. Table 2-7provides details about the available options. The options listed are consistent with options for earlier Superdome systems.
