42-position circuit breaker panel—Each PDU has a circuit breaker panel with 42 pole positions. Each pole provides power at 120 volts L-N or 208 volts L-L. The amperage each position provides depends on the size of the circuit breaker used.
Panel current sensors— Wires that feed the distribution panel pass through these current sensors, providing data to the PDU monitoring unit.
PDU monitoring unit—The PDU monitoring unit receives signals from several current and voltage monitoring boards that report to a central board assembly located in the PDU monitoring unit. The monitoring unit has one 10Base-T (Cat-5) connection to the Information Controller Hub (or switch), four (4) relay output connections, four (4) input contact connections, and one (1) EPO input connection. Make these connections at the user connection plate located on the roof of the PDU. See “PDU monitoring unit” on page 10 for a more detailed description.
Input transformer—The delta-wye transformer installed in your PDU is based on your input voltage (208V, 480V, or 600V input). The output of the transformer feeds the input circuit breaker of the maintenance bypass panel. (APC also offers a 208V PDU without a transformer.)
Load test ports—The load test ports are an available option on the PDU. The load test bank connector allows a UPS system to be load-tested to ensure that the system will operate according to specifications if a power outage occurs.
