Table 3-1 “Available Power Options” describes the available
power options. It may be unusual to list Options 6 and 7 and not
1 and 2. The options listed are consistent with previous options
for earlier Superdome systems. Table 3-1 Available Power Options | Option | Source Type | Source Voltage (nominal) | PDCA
Required | Input Current Per Phase 200-240 VAC [1] | Power Receptacle Required |
|---|
| 6 | 3-phase | Voltage range 200-240 VAC, phase-to-phase,
50
Hz or 60 Hz | four-wire | 44A Maximum per phase | Connector and plug provided with a 2.5-meter power
cable. Electrician must hard-wire receptacle to 60A site power. | | 7 | 3-phase | Voltage range 200-240 VAC, phase-to-neutral,
50
Hz or 60 Hz | five-wire | 24A Maximum per phase | Connector and plug provided with a 2.5-meter power
cable. Electrician must hard-wire receptacle to 32A site power. |
Table 3-2 Option 6 and 7 Specifics PDCA
Part Number | Attached Power Cord | Attached Plug | Receptacle Required |

A5201-69023
(Option 6) | OLFLEX 190 (PN 600804) is a 2.5 meter
multi conductor, 600 volt, 90 degree C, UL and CSA approved, oil
resistant flexible cable. (8 AWG 60 A capacity) | Mennekes
ME 460P9
(60

ME 460R9
(60

(Option 7) | H07RN-F (OLFLEX PN 1600130) is a 2.5
meter heavy duty neoprene jacketed harmonized European flexible
cable. (4 mm2 32A capacity) | Mennekes
ME 532P6-14 (32A capacity) | Mennekes
ME 532R6-1500
(32

| | | |  | NOTE: A qualified electrician must wire the PDCA receptacle
to site power using copper wire and in compliance with all local
codes. | | | | |
Each branch circuit used within a complex must be
connected together to form a common ground.
When only one PDCA is to be installed in a system cabinet,
it must be installed as PDCA0. Refer to Figure 3-1 “PDCA Locations” for PDCA0 location. | | | | | NOTE: When wiring a PDCA, phase rotation is unimportant. When
using two PDCAs, however, the rotation must be consistent for both. | | | | |
Power Cords | |
This section discusses the different possibilities for PDCA
power cords. Some installations may either require or desire that the cabinet(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 3-5 “PDCA Cable Access (5-Wire Unit Shown)”. Then remove the bottom panel of the PDCA.
Retain the panel and screws for future use. | | | | | 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 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 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 3-7 “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 3-5 “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.
| | | | | 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 3-7 “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. | | | | |
