Installing the Octel Overture 200/300 With –48-Vdc Power Supply
Unit
The –48-Vdc powered server does not include a power cord. A terminal block is provided on the back of
the cabinet for field wiring to the d.c. power source. The installation must be performed as described
below, to comply with National Electrical Code (NEC) and UL regulations. In addition, use only those
materials mentioned, because they must also be controlled. Field-wiring material is not included with the
server, but it can be obtained from a local hardware store or qualified electrician.
List of Materials
The following materials are required for the installation:
- 1/2-inch diameter conduit.
- UL-approved, insulated, stranded wire to run through the conduit. Three separate wires must be
connected; therefore, use three different wire colors. The grounding conductor insulation should be
green and yellow.
- The wire size for the Octel Overture 200 must be 12-gauge (3 mm 2 ).
- The wire size for the Octel Overture 300 must be 10-gauge (5 mm 2 ).
The d.c. version of the Octel Overture 200/300 must be field-wired and connected to
a branch circuit equipped with a branch-circuit overcurrent-protection device, set at
the following:
- 20 A maximum, 60 Vdc for the Octel Overture 200.
- 25 A maximum, 60 Vdc for the Octel Overture 300.
.
The conduit and the UL-approved, insulated stranded wire can be obtained preassembled.
- Six forked, crimp-on terminals with upturned ends for the wire size and a #10 screw.
- Conduit strain relief to fit a 1.10-inch-diameter hole in the sheet metal.
