Installing Rectifier Modules into the Valere Power
Shelf
The ODC-3000 cabinet uses two Valere compact power systems to generate and distribute
-48 VDC bulk power. Each Valere power system consists of a 19-inch G-series power shelf
and a 23-inch DC distribution shelf. Valere system 1 (located at the top of the right bay when
viewed from the front) supports C7 shelves 1 and 2, heat exchangers 1 and 2, and battery
strings 1, 2, and 3. Valere system 2 (located at the top of the left bay when viewed from the
front) supports C7 shelves 3 and 4, heat exchangers 3 and 4, and battery strings 4, 5, and 6.
Each Valere power shelf supports up to four rectifier modules (20A or 30A options). Normal
operation for the ODC-3000 cabinet requires a minimum of two rectifier modules per Valere
shelf (one module per supported C7 shelf). Use additional rectifier modules to support high-
loaded systems, provide module redundancy, faster battery charging time, or powering for
third-party equipment. Each Valere power shelf is equipped with a controller module that
monitors power functions and alarm information and regulates voltage in response to battery
temperature. The master controller module (BC-2000) resides in shelf 1 and features a 16-
character front panel display for programming menu-driven system controls. A slave
controller module (EC-1000) resides in shelf 2. For a complete description of the Valere
power shelf, refer to the
Valere Compact DC Power System Installation and Maintenance
manual
.
The Valere DC distribution shelves provides distribution of -48 VDC power to equipment
and batteries. Each distribution shelf is equipped with six load breaker positions, 10 GMT
fuse positions, and six battery breaker positions. The typical configuration for an ODC-3000
cabinet includes four 30A load breakers (A and B power feeds to two C7 shelves), three 40A
battery breakers (three battery strings), and two 5A GMT fuses (heat exchangers). For a
complete description of the Valere DC distribution shelf, refer to the
Valere DC Distribution
Panel
manual

Install Valere modules into the power shelves as described below.
