Power connector requirements
Ensure that the site where you plan to install the DS8000 storage units meets the
power connector requirements.
Table 55 provides the power cords and the inline connectors and receptacles types
that they support. Find the power cord row that is appropriate for your site.
Ensure that the site where you plan to install the DS8000 storage units meets the
power connector requirements that are shown in that row.
Phase rotation on 3-phase power-cable connectors is counterclockwise as you look
at the power cord plug. Phase rotation is clockwise as you look at the face of the
power receptacle at your installation site.
Attention:
v Low-voltage, three-phase installations (200-240 V) require wall circuit breakers
that have a rating of 50 to 60 A.
v
High-voltage, three-phase installations (380-480 V) require wall circuit breakers
that have a rating of 30 to 35 A.
Note: Special applications that use 30 A power cords must rely on 30 A wall
circuit breakers for power cord protection.
Do not exceed the wire rating of the facility.
