3-Phase AC Cabling for USA
Connecting the External Power Supply Cord
Branch Circuit Requirements
Preparing for Installation
The DKU has two power supply cords. If one power source malfunctions,
the other power source will assume the total load, causing no data loss. It is
also good practice to put each power cord on a different electrical circuit, in
case of a circuit failure. Each power supply cord is supplied with an
attachment plug type R&S FS 3760. Be sure to prepare the following
socket receptacles between the power distribution board of the building and
the attachment plugs for the unit:
Socket receptacle: R&S FS 3754 or FS 3934 (or equivalent)
To protect your disk array, your building must be wired correctly. Each line
(R/S/T line) should be protected by a short circuit protective device and by
an overcurrent protective device rated 30 amp on building installation.
