Installing the Hardware Hardware Installation

For safety, observe all of the following conditions for DC power connections.

Table 3-3 DC power safety conditions

All power connection wiring should conform to the rules and regulations in the National Electrical Code

(NEC), as well as any local codes.

Each DC-input power supply connection is rated at 60A maximum. A dedicated, commensurately-rated DC

power source is required for each power entry module connection.

For DC power cables, Riverstone recommends that you use commensurately rated, high-strand-count

copper wire cable. Connection to the DC-input power supply requires one earth ground cable for the power

supply and two cable leads (a DC source and a DC return) for each power supply. The length of the cables

depends on your RS 32000 location. These cables are not available from Riverstone. They are available

from any commercial cable vendor.

DC power cables must be terminated by cable lugs at the power supply end. The lugs should be able to fit

over 1/4-20 terminal studs.

The source of power for the DC power supplies must be a reliably grounded SELV source.

Branch circuit overcurrent protection must be rated a maximum of 60A.

A readily accessible disconnect device that is suitably approved and rated should be incorporated in the

field wiring.
