Attention: Ensure that there is a local site disconnect and/or isolation means
(such as a service branch circuit breaker, power feed switch, and/or wall socket
outlet to an industrial style plug) for each AC main power cord to a system. The
internal rack (system side) appliance cord coupler is NOT intended to be
connected or disconnected live. Follow local electrical authority site regulations for
proper isolation practices such as Lock Out Tag Out (LOTO) and/or approved
procedures.
DANGER
Appliance coupler connector is not intended for AC (Alternating Current -
Voltage) electrically live plugging nor for interrupting current. Remove and/or
isolate input power from the wall end (service branch circuit) to the power
cord before attaching or disconnecting the machine end (appliance coupler).
Input voltage requirements
When you plan for the power requirements of the storage system, consider the
input voltage requirements.
The following table provides the input voltages and frequencies that the storage
system supports.
Table 77. Single-phase input voltages and frequencies
Characteristic Voltage (single-phase)
Nominal input voltages 200-240 RMS V AC
Minimum tolerated input voltage 180 RMS V AC
Maximum tolerated input voltage 256 RMS V AC
System maximum current rating DS8886 40 Amps
DS8884 24 Amps
Wall breaker rating (1 ph)
1
DS8886 US, Canada, and regions that require
20% derating factor 50 - 63 Amps
DS8886 Geos with no derating requirement 40 -
63 Amps
DS8884 All regions 30 - 63 Amps
