Branch circuit requirements

Electrical Specifications
cord have a separate electrical circuit as its source, in case of a circuit
failure. Each power-supply cord is supplied with an attachment plug type
Russellstoll 3760PDG.
Be sure to install Russellstoll 3934 (alternate, 9C34U0) or 3754 (alternate,
39R34U0W) socket receptacles between the power distribution panel of the
building and the power plugs for the unit.
The power cords provided with the disk array are nonshielded, type ST or
equivalent with four #8 AWG (minimum) conductors terminated at one end
with an assembled plug connector.
To protect the disk array, your building must be wired correctly. Each
supply ("hot") conductor must be protected by a short-circuit protective
device and by an overcurrent protective device. Table 25
Table 28 (page 72) provide specifications for the overcurrent protective
devices required for three-phase operation.
All protective devices must comply with national standards of the country
where the units are to be installed. If a protective device interrupts any
supply conductor, it must also interrupt all other supply conductors.
Overcurrent protection is not required for the neutral conductor of this unit.
Only 50 Hz, three-phase configurations have a neutral conductor.
