Electrical Specifications

This section provides electrical specifications for Superdomes.

Grounding

The site building shall provide a safety ground/protective earth for each AC service entrance to all Superdome cabinets.

This equipment is CLASS 1 and requires full implementation of the grounding scheme to all equipment connections. Failure to attach Protective Earth results in loss of regulatory compliance and creates a possible safety hazard.

Circuit Breaker

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

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




	NOTE: See Table E-1 “Typical Superdome Configurations” for systems that are configured with less than a full compliment of cell boards, memory, and I/O modules.When using the minimum sized breaker, always choose circuit breakers with the maximum allowed trip delay to avoid nuisance tripping.As of March, 2002, PDCA Options 4 and 5 are obsolete.

Detailed site power information is required to configure the system correctly and prevent delays in system installation. Collect the following information from the customer site electrician before selecting the appropriate PDCA.

Type of source available 4-wire_____ 5-wire_____
Source voltage phase-to-phase _____ Vac
Source voltage phase-to-neutral _____Vac

Using the above information, determine the appropriate power option from Table 1-6 “Available Power Options”.

Select the source type that matches the customer source.
Within the matching Source Type selection, select the matching voltage range to the customer's source voltage.
Select the appropriate PDCA.
The customer must either provide the correct mating in-line connector or order one from HP. See Table 1-8 “Options 006 and 007 Specifics” for details.

Example 1-1 The customer has a 3-phase source with a Source Voltage of 208 VAC measured phase-to-phase indicating that a 4-wire PDCA is required.

Example 1-2 The customer has a 3-phase source with a Source Voltage of 220 VAC measured phase-to-neutral indicating that a 5-wire PDCA is required.

Example 1-3 The customer has a 3-phase source with a Source Voltage of 230 VAC measured phase-to-phase indicating that a 4-wire PDCA is required.

Example 1-4 The customer has a 3-phase source with a source voltage of 415 VAC measure phase-to-phase and a measured phase-to-neutral source voltage of 240 VAC, indicating a 5-wire PDCA is required.

	NOTE: A qualified electrician must wire the PDCA in-line connector to site power using copper wire and in compliance with all local codes.

Each branch circuit used within a Superdome Complex must be connected together to form a common ground.

When only one PDCA is to be installed in a Superdome, it must be installed as PDCA 0. Refer to Figure 1-5 “PDCA Locations” for PDCA 0 location.




	WARNING! Do not install a PDCA that does not have one of the following set of labels attached.

Figure 1-5 PDCA Locations

Power Cords

This section discusses the different possibilities for Superdome PDCA power cords.

Pre-wired PDCAs Options 6 and 7

All Superdomes are delivered with the appropriate cable and plug. The mating in-line connector is not provided.




	IMPORTANT: Verify that the source power is correct for the appropriate PDCA wiring.




	NOTE: When installing the power connector, allow enough room for mating the connector with the plug.

Check the voltages at the connector prior to connecting the newly installed connector to the PDCA plug. Refer to Figure 1-7 “Four-Wire In-Line Connector (A4660A Opt 401)” and Figure 1-8 “Five-Wire In-Line Connector (A4660A Opt 501)” for pin locations.

To verify the proper wiring for a 4-wire PDCA, use a DVM to measure the voltage at the in-line connector. Voltage should read 200 - 240 Vac phase-to-phase as measured between the connector pins as follows: L1 to L2, L2 to L3, L1 to L3.
To verify the proper wiring for a 5-wire PDCA, use a DVM to measure the voltage at the connector. Voltage should read 200 - 240 Vac phase-to-neutral as measured between the connector pins as follows: L1 to N, L2 to N, L3 to N.

Figure 1-6 PDCA Assembly for Options 6 and 7 (4-Wire Unit Shown)




	IMPORTANT: Ensure that your DVM is capable of measuring AC voltages of at least 500VAC. A number of 5-wire power distribution systems may have phase-to-phase voltages in excess of 400VAC. Many hand-held volt meters are limited to 300VAC.

Figure 1-8 Five-Wire In-Line Connector (A4660A Opt 501)

Cable Removal

Some installations may either require or desire that the Superdome(s) be hardwired in lieu of using the standard plugs and connectors provided. In these cases, it is necessary to remove the installed power cable from the PDCA. The following procedures are used to remove and replace the existing power cable.

To remove the existing cable from the PDCA, begin be removing the five T-10 Torx screws detailed in Figure 1-9 “PDCA Cable Access (5-Wire Unit Shown)”. Then remove the bottom panel of the PDCA. Retain the panel and screws for future use.




	NOTE: The cable removal and installation requires only the bottom panel to be removed. For image clarity, Figure 1-9 “PDCA Cable Access (5-Wire Unit Shown)” does not show cable or cable strain relief.

Locate and remove the PDCAs.
Remove the five screws securing the bottom of the PDCA. Retain the screws. Refer to Figure 1-9 “PDCA Cable Access (5-Wire Unit Shown)” for details.
Disconnect the existing wires from the PDCA terminal lugs. Refer to Figure 1-9 “PDCA Cable Access (5-Wire Unit Shown)” for details.
NOTE: Loosen the cable side terminal lugs only. Do not loosen the PDCA side terminal lugs.For 5-wire cables, loosen four lugs. For 4-wire cables, loosen three lugs.
Using an 11-mm socket, remove the safety ground cable (green and yellow cable). Retain the attaching hardware.
Remove the cable from the PDCA. Keep all retaining hardware for use during installation of the new cable.

Cable Installation




	NOTE: These procedures may be used for early deliveries consisting of either option 1 or option 2 as well as those later systems delivered with PDCA cables attached.

Select the proper cable using the following criteria.

Each Superdome cabinet using a 3-phase, 4-wire input is required to have a four-conductor cable. The four-conductor cable selected by the facility electrician shall be in accordance with local electrical codes to support the selected circuit breaker for the maximum Product Label current of 44A per phase. The facility electrician and local electrical codes will determine proper power cord selection dependent upon desired application such as rigid conduit, flexible conduit, or cable bundle. Observe derating factors for multiple wires per cable.
Each Superdome cabinet using a 3-phase 5-wire input is required to have a five-conductor cable. The five-conductor cable selected by the facility electrician shall be in accordance with local electrical codes to support the selected circuit breaker for the maximum Product Label current of 24A per phase. The facility electrician and local electrical codes will determine proper power cord selection dependent upon desired application such as rigid conduit, flexible conduit, or cable bundle. Observe derating factors for multiple wires per cable.

Prepare the new cable as shown in Figure 1-11 “Cable Preparation Detail”.
Using the cable retaining hardware saved from the cable removal, route the new cable into the PDCA.
Route the cable into the PDCA terminal lugs and secure in position by tightening the lugs.
Using the hardware that was retained during the cable removal, attach the green and yellow ground cable.
Using the five screws retained from the removal procedure, replace the bottom panel on the PDCA. Refer to Figure 1-9 “PDCA Cable Access (5-Wire Unit Shown)” for panel installation details.

To verify the proper wiring to a 4-wire PDCA, use a DVM to measure the voltage at the test points. Voltage should read 200 - 240 Vac phase-to-phase as measured between the test points as follows: L1 to L2, L2 to L3, L1 to L3.




	IMPORTANT: In some electrical distributions around the world, it is possible to measure 415 VAC phase-to-phase. Ensure that your DVM is capable of measuring AC voltages of at least 500VAC. A number of 5-wire power distribution systems may have phase-to-phase voltages in excess of 400VAC. Many hand-held volt meters are limited to 300VAC.

To verify the proper wiring to a 5-wire PDCA, use a DVM to measure the voltage at the test points. Voltage should read 200-240VAC phase-to-neutral, as measured between the test points as follows: L1 to N, L2 to N, L3 to N.

Figure 1-11 Cable Preparation Detail




	NOTE: Dimensions shown are for a cable strain relief without an extension nipple. If an extension nipple is used, then the cable jacket must removed accordingly. Figure 1-11 “Cable Preparation Detail” shows a 4-wire cable for illustrative purposes only. 5-wire cable is dimensionally identical regarding insulation and jacket removal. The only exception is the number of conductors.

Customer Installation Options

Figure 1-14 “PDCA Conduit Connection” and Figure 1-15 “Conduit Required for PDCA Connection” detail a suggested configuration for connecting the PDCA when the use of rigid conduit is required or desired. Using a 2- to 4-inch nipple and a 90o elbow allows the conduit to pass through the raised floor at a point immediately past the cabinet. This prevents the conduit from extending beyond the cabinet.
