Table 49 on page 271 describes the electrical specifications for the
Symmetrix DMX-3 system bay and storage bays for systems installed
in North American, three-phase, Delta environments.

extension cords and
mating connectors
Each DMX-3 system bay and storage bay has two PDPs with a power
cable affixed to each PDP shown in Figure 61 on page 270. For a
North American, three-phase, four-wire configuration, affixed to each
PDP power cable is a 50A Hubbell CS8365C or an equivalent 8365
type connector (Delta). Table 50 on page 271 describes the optional
EMC extension cords that connect to this Hubbell connector and
mating connector options.

Power requirements at customer site (minimum) Two 50 A three-phase drops per bay
a. An imbalance of AC input currents may exist on the three-phase power source feeding the Symmetrix system, depending on configuration.
The customer's electrician must be alerted to this possible condition to balance the phase-by-phase loading within the customer's data
center.
